These two photos depict two wolf hybrids.
The animal on the left, with its floppy ears and black-and-tan coat, is an F1 wolfdog from Wildlife Park Kadzidlowo in Poland. He was intentionally bred from a “Polish spaniel” dog and a European wolf bitch. I am not sure what breed of spaniel the father was, but this hybrid reminds me very much of the Gråwachtel, a German spaniel (“wachtelhund”)/Norwegian gray elkhound cross. The dog features predominate. It looks like nothing more than a really feral-looking retriever type dog.
The animal on the right is a first generation cross between a West Siberian laika dog and a female wolf. Breeding West Siberian laikas to wolves is really nothing new, and the practice continues in Russia to this day. Knowing the politics of wolf hybrids in the United States, it might not be wise to discuss this feature in the West Siberian laika. There is a certain politically correct movement that views any sort of wolf hybrid as a skittish, dangerous animal, when in reality, the animals vary quite a bit. Having been around a West Siberian laika, I can attest that they are less wild and skittish than many other Nordic breeds.
The truth is you can’t tell a wolf hybrid by just looking at it. If the dog in the cross has floppy ears, it’s not going to look like a wolf at all. It may act more like a wolf.
Or maybe not.
The differences between wolves and dogs are more complex than you might think.
Unfortunately, this problem gets worse when certain people make absolute claims about wolves, dogs, and wolf hybrids.
The one absolute claim one should follow is always be leery of absolutes!
When someone says “never” or “always,” they are setting themselves up for error. All it takes is one example that goes counter to the claim to make it false.
And that’s what happens.
There are pure wolves that are as docile as golden retrievers when they are brought up imprinted upon people.
There are also dogs that are very reactive and nervous and only bond to a few people– just as most captive wolves do. There are pure wolves that have made decent hunting and working dogs.
There are wolf hybrids that have killed people, and there are wolf hybrids that have been the perfect pets.
Because of the complexity of the wolf and dog question, I cannot consider dogs and wolves distinct species. There is just too much overlap between dog and wolf to make such absolute distinctions.
I will use Canis lupus familiaris to describe the dog.
I think one of the biggest obstacles to getting people to understand why wolves are dogs is that the only wolves people seem to know about are the big wolves from northern ranges. What they don’t realize is that these wolves are not the totality of their species. They are actually a fairly specialized variant that evolved in the northern parts of Eurasia and North America to hunt things like moose, caribou, elk/wapiti, bison, aurochs, and muskoxen.
There are also wolves that are much smaller in the Middle East, South Asia, and yes, Africa, that are much more dog-like, and at least one study points to Middle Eastern wolves as being the primary source for most of the genetic diversity in the dogs we have today.
Wolves are actually a very diverse species, and historically, they were even more so. Dogs are just a reflection of their ancestral species diversity. Once removed from the rigors of natural selection, humans can play with that ancestral wolf genome to produce what is really the most morphologically diverse population in the world.
One cannot tell a wolf hybrid just by its appearance.
And one cannot always tell a wolf by its appearance either.
The facility that bred it actually said it was actually 1/8 Great Pyrenees!
Wolves and dogs are wild and domestic populations of the same species.
The wolf itself is really a vestige of what was once a very diverse species.
Wolves managed to range over almost all of Eurasia and all of North America from the Valley of Mexico to Greenland. Their range in Africa has only recently been revealed through genetic studies.
And this species became successful because it could adapt its morphology– perhaps rather rapidy– to fit new ecosystems and prey sources.
To live in the same places, humans adapted new technologies. Wolves adapted their bodies through evolution.
A domestic dog is just a wolf that has evolved to live with humans. It’s a different niche, and humans did quite a bit of selective breeding to produce unusual body types.
But the body template and the vast majority of the genome are still those of a wolf.
Dogs are wolves in terms of their phylogeny and genes.
They may look very different now.
And dogs may be much better adapted to living with people.
But dogs and wolves haven’t diverged that much.
And when a floppy-eared dog mates with a wolf, the results can be somewhat disconcerting.
We expect the wolf dogs that result from the mating to look like wolves and not Labrador crosses.
It takes us aback.
And it makes us wonder.
The top image comes from this recent study that confirmed hybridization between male wolves and female dogs in the Baltic states.
Previous “naturally occuring” wolf dogs in Europe have all been between male dogs and female wolves, which is one reason why the studies that one cannot use mtDNA studies on European wolves to confirm or deny the introgression of dog genes into the wolf population.
There will be more on this study in a future post.
Recessive black is most commonly found in German and Belgian shepherds. It can also be found in pulik, Samoyeds, schipperkes. Shetland sheepdogs, and the so-called “American Eskimo dog,” which is actually an American variant of the German spitz.
It’s one of two ways that a dog can be solid black, but it’s far less common than dominant black.
The mutation that causes dominant black originated either in dogs or the wolf population that became dogs, because the mutation is older in domestic dog populations than in wolves. This black coloration wasthen transmitted to Italian and New World wolves through cross-breeding with domestic dogs. All wolves that have been examined in North America thus far have turned out to be dominant blacks, as have those in Italy.
However, there was at least one case of a wolf carrying recessive black in the literature.
The Soviet zoologist and dog expert N.A. Iljin carried out several experiments crossing various dogs with wolves. In 1941, he reported on the progeny of a male wolf that was bred to a female mongrel sheepdog. In the first litter, there were black and “zonar gray” (wild wolf gray puppies). If the dog in question were a dominant black, then the entire litter would have been black, but getting gray puppies suggested a very different conclusion.
After breeding from the offspring for several generations, Iljin discovered that the black was being inherited as a recessive allele, which means the dog in question was a recessive black– and the wolf was a carrier!
Now, results of Iljin’s study have been used to show that wolves carried recessive black from the beginning.
However, since the time of Iljin’s work, no one has found a recessive black wolf. The team of geneticists at UCLA have found only dominant black in wolves.
So it’s possible that this wolf was not actually “pure,” and at some point, one of its ancestors was a recessive black dog. I would not be surprised if someone had crossed a recessive black German shepherd into captive Russian wolves at some point. Iljin himself was very much into breeding German shepherds to wolves, and his studies on wolf and German shepherd morphology are pretty much classic literature for those interested in wolves and dogs.
So maybe recessive black did exist in certain Old World wolves from the beginning, but it’s just not been confirmed in the genetic literature in the same way that dominant black has.
I don’t know of another species besides Canis lupus that has two separate genetic variants for melanism. Coyotes have inherited dominant black from breeding with either dogs or wolves, and golden jackals and Ethiopian wolves could also inherit both types of melanism through similar hybridization.
So it’s very interesting that we have this one case of a wolf carrying recessive black, but we need more information to see where this color came from.

The Kentucky frontier wasn’t the only place that wolves were used as hunting dogs. Wolves were also commonly used as hunting dogs on the Pennsylvania frontier. They were also crossbred with “improved” Western dogs to make superior working animals, but the practice was largely discontinued when it was decided that every farm ought to have a “purebred” collie or shepherd.
Henry Wharton Shoemaker was a polymath of sorts. He was a Columbia graduate, who worked on Wall Street and for the US foreign service before moving to Pennylvania to work as a newspaper publisher. He became well-versed in the folklore and local history of the mountainous regions of Central and Western Pennsylvania, and it is from his writings on this subjects that we can find out what the original settlers thought of different animals. He was an ardent conservationist, and he worked as writer for Gifford Pinchot’s campaigns for the US Senate and for governor of Pennsylvania.
His interests as an historian, conservationist, and folklorist brought him to write two volumes on the history of the extinct animals in Pennsylvania. One volume would cover wolves and “panthers” (the creatures also known as cougars/pumas/mountain lions/catamounts), and another would cover the other extirpated species. These two volumes are often compiled into a single volume called Extinct Pennsylvania Animals, which is traditionally the name for the second volume. The second section of the first volume is called Wolf Days in Pennsylvania, and it was originally published in 1914.
Through his research and interviews with those who had first hand accounts with these animals, he found that the settlers believed that there were three kinds of wolf in Pennsylvania. There was a large gray wolf and a large black wolf, but these appeared to breed true, even though it wasn’t unusual for a black wolf to whelp a gray pup. And there was a small brown wolf, which sounds suspiciously like an account of the existence of an eastern population of coyotes. I think the corpus of the evidence– particularly the genetic evidence–suggests that coyotes did exist in the East, but they were extirpated with the wolves. As the larger wolves were removed from other parts of their range, the smaller coyotes were able to file back into the East again. (The so-called red wolf is largely a fictional animal.)
The settlers in Central and Western Pennsylvania considered the black wolf to be a separate species from the gray. The gray and “small brown wolves” were easily killed, but the black ones were much more cunning and wary. In what might sound like a contradiction, it was very common for these black wolves to be socialized to people and then used as hunting or working dogs.
As far as intelligence went, the black wolf was far the superior of the others. It was susceptible of domestication, and would have made the ideal hunting dog of Pennsylvania….Dr. W. J. McKnight, in his “Pioneer Outline history of Northwestern Pennsylvania,” states “the pioneer hunter would sometimes raise a wolf pup. This pup would be a dog in every sense of the word until about two years old, and then would be a wolf in all his acts.” Audubon in his “Quadrupeds of North America” says: “Once when we were traveling on foot not far from the Southern boundary of Kentucky, we fell in with a black wolf, following a man with his rifle on his shoulder. On speaking with him about this animal, he assured us that it was as tame and gentle as a dog, anr) that he had never met a dog that could trail a deer better. We were so much struck with this account and the noble appearance of the wolf, that we offered him one hundred dollars for it, but the owner said he would not part with it for any price.” What was the case in the West, was equally true in the Seven Mountains and in Clearfield and Jefferson Counties. One or two of the earliest hunters trained black wolves to act as hunting dogs and companions. These and wild black wolves bred with dogs owned by pioneers, producing a really worthy progeny. St. George Mivart has said “hybrids between the dog and the wolf have proved to be fertile, though for no long period.” The writer remembers that in his early boyhood about twenty years ago he saw several of these wolf-dogs. They were intelligent and kindly, and highly prized by their owners, farmers in some of the valleys adjacent, to the Seven Mountains. The craze for handsome sheep dogs or collies which struck the valleys about this time resulted in ending the breeding of the wolfish clogs, which to those not in sympathy with them, were technically mongrels, and they eventually disappeared. There are probably few of them now in existence. Their owners declared that they never showed the slightest tendency to revert to a wild state. In September, 1898, the writer visited a farmer, who tilled some back lots at the foot of the mountains on the South side of Brush Valley not far from Minnick’s Gap. This old fellow, Abe Royer by name, kept some turkeys, half wild, which were the result of his tame turkey hens crossing with wild gobblers which lived on the mountain back of his cabin. He had preserved several wild pigeons until 1895, to be used as “stool pigeons” in the event of the great flocks “returning.”
He also kept several wolf-dogs. These animals had dun and grey coloring not unlike collies, but had the shorter hair and longer legs of wolves. There was no trace of black in their coloring, although their owner stated that their grand-sire had been a black wolf which coupled with a shepherd bitch some ten years before when he was lumbering for Ario Pardee in High Valley. He said that neither turkeys nor dogs had the least inclination to revert to the savage proclivities of their ancestors. If the grey wolves and the brown wolves had any of the admirable characteristics of their black relatives, the old hunters sayeth not. “Crafty and mean” is the general verdict expressed about the grey wolves, “nasty like little cur dogs,” is the general run of remarks relative to the brown wolves. Doubtless these uncomplimentary characterizations are unjust to the animals, but they were certainly not up to the standard of the black wolves. If all are of one variety these attempts at specialization are hardly worth the time to read. At the same time it may show that color in animals has much to do with habitation, character and disposition. It may help to reveal the secret of why some men are blonde and others dark (pg. 24-25).
The black coloration in North American wolves is thought to have originated through crossbreeding with Native American dogs, but the dog ancestry in these wolves probably wouldn’t have been a high enough percentage to have affected their temperament. Modern black wolves are, for all intents and purposes, very much wolves.
The black coloration is a simple dominant trait, so it is possible that certain populations of wolf in the Eastern United States were consisted of almost of nothing but melanistic individuals. This dominant black trait in dogs, wolves, and coyotes comes from a mutation that controls the protein beta-defensin 3. This protein does regulate the amount of melanin that appears on the dog, wolf, or coyote’s coat, but it also is associated with immune response. Having this particular mutation might provide the wolves with some advantages in fighting off viral and bacterial infections, which may have been more common in the temperate and subtropical forests of North America.
I don’t think these black wolves were a different species at all, but for whatever reason, this particular type of wolf was easily domesticated. It may have been that this was a sort of intermediary animal that included the genetics of both wolves and domestic dogs, and there was some continual hybridization between the two forms. And that might be why these wolves were so easily domesticated.
It is possible that the black coloration could have been associated with a tendency toward domestication. A very similar finding was found with black deer mice, which were found to be more docile than the more common agouti deer mice.
But black deer mice have a different genetic basis than black wolves or dominant black dogs, so one should be careful about making generalizations from that study and trying to apply them to the tame wolves of the Pennsylvania.
These domesticated wolves appear to have been very much a part of life in America in the early days of settlement. These settlers of the Pennsylvania mountains didn’t have access to the best lines of Western hunting dogs, so they improvised. They found that the black wolves were a good outcross to their curs and shepherds.
So here we have another account of modern people keeping wolves as working and hunting dogs.
See earlier posts
This dog’s image comes from a site that says it is 40 percent “Timberwolf” and 60 percent “Norwegian elkhound.”
I don’t know if those percentages are accurate or if this dog has any recent wolf ancestry at all.
But it is said to howl. Norwegian elkhounds really don’t howl. They are know for their barks. I remember my grandpa’s elkhound would rake his back on the lower rung of a split-rail fence in the front yard, and he would bark each time he raked his back against the rail.
I don’t know why anyone would puff an elkhound as being part wolf.
I am skeptical that this particular dog is of recent wolf ancestry. It might be. It looks more like a wolf than the F1 poodle/wolf crosses that Erik Zimen bred.
The dog on the right is a cross between a low content wolf dog and a Labrador. The dog on the left is his son, produced through mating with a black Labrador mix.
Here is the low content wolfdog with his grandson and “daughter-in-law.”
My guess is the majority of the litter were black, but this one wasn’t. There also had to be a gene for the black mask in the Labrador mix mother.
NB: I use the term “wolfdog,” rather than wolf hybrid. Dogs and wolves are part of the same species, Canis lupus, and can’t technically be hybrids. However, crosses between dogs and coyotes and crosses between wolves and coyote would be hybrids.
Garry was registered with the Kennel Club as an “Esquimaux dog” and was exhibited at the Alexandra Palace Exhibition and the “Birmingham dog show” (Crufts?) in 1876. He was said to be an “Eskimaux [dog] bred in the far north of Lombardy.”
This depiction of him comes from Hugh Dalziel’s British Dogs (c. 1880). Dalziel was of the opinion that he was not a wolf or wolf hybrid. However, I have a certain amount of skepticism about Dalziel’s reasons for assuming that Garry was a pure dog, which I shall get to in good order.
Dalziel reports the description of Garry from his own C.E. Fryer:
Mr. C. E. Fryer, whose notice of Garry we reproduce from The Country, entitled him a “North American wolf dog,” and we find the idea that these dogs, or at least special varieties of them, are produced by a cross with the wolf rather commonly entertained, but there is no better reason for it than his general wolfish appearance. Garry is decidedly typical of the Esquimaux family of dogs, and on the subject of his breeding we have little to add to our sub-note to Mr. Fryer’s letter at the time it first appeared.
Mr. Fryer says: “The accompanying engraving represents one of these curious dogs, which are so much prized by the natives and inhabitants of North America, and so difficult to obtain in this country. The cut is taken from a photograph of a dog lately owned by a member of Oxford University, who gave me the following account of it: Garry, the dog in question, is about eighteen months old, and has been in this country seven months. He was brought from the Saskatchewan Mountains, Manitoba, in the far north-west of Canada.
Fryer’s geography is a bit off. Manitoba is in the middle of Canada, and I have never heard of any “Saskatchewan Mountains” in Saskatchewan or Manitoba.
Dalziel describes Garry’s origin:
The Indians take great pride in rearing a pure white wolf dog, and when they manage to secure one they have a feast in his honour, called the ‘ Feast of the White Dog.’ I refrain from attempting the native names, lest I should display my own ignorance and do some damage to my readers’ jaws. Garry is said to be the produce of an Esquimaux bitch, crossed nine times by a prairie wolf. The Indians chain up the Esquimaux mothers in the neighbourhood of the wolves, to whose kind attentions they leave them. The dog Garry has travelled many thousand miles over the snow, drawing a sleigh, and is quite tame, following his master closely through the streets without chain or muzzle. Sometimes he is treated to this latter sign of ‘civilisation,’ under which he is very patient, though he continually endeavours to free himself from it. His food is plain dog biscuit, which he eats without complaint, though at first he ate raw meat ravenously. His master, however, finding his blood was getting too hot, gradually reduced him to one meal per day of dog biscuits. He is very tractable and docile, and but for his enormous size would not give any idea of ferocity.
This would have made Garry a very high content wolfdog, and judging from this depiction of him, I would have no reason to doubt that he was either a high content wolfdog or even a possible pure wolf.
His behavior appeared to have been quite wolf-like:
His owner tells me he does not bark, but utters a low growl when enraged, and at night howls piteously.
And his teeth sound as if they were those of a wolf, not a domestic dog:
His mouth would easily take in a man’s leg, and his teeth are a caution to dentists. Whether he feels flattered by being told that we are possessors of developed ‘ canine ‘ teeth I can’t say.
Wolves and coyotes have much more robust teeth than domestic dogs do. The big game hunting specialist wolves have particularly large teeth, and if Garry were a wolf or a wolf hybrid, he would have been of this type.
Of course, Hugh Dalziel didn’t think that Garry was any kind of wolf or wolf hybrid:
The mystic story of Garry’s birth and parentage is very charming, but I fear the talismanic number nine would alone be fatal to it, as it is decidedly suspicious; and in these days of Kennel Stud Books we get awfully sceptical of unauthenticated pedigrees, and in such matters positively refuse as evidence the traditions of the Red Man, however pretty and romantic. I saw Garry in the flesh at Birmingham – where, by the way, he took a £5 prize – and I must pronounce him the very finest specimen of an Esquimaux dog I have seen, but I must differ from our esteemed correspondent when he says there is unmistakeable evidence of wolf blood in the dog. Dogs appear to approach nearer to the wolf type the farther they are removed from the higher civilised life of man, and that, I think, is the case with Garry, and, besides that, hybrids do not breed.
Actually, there have been wolves that have been imprinted upon people are quite docile animals. There is the story of Wags, Adolph Murie’s pet wolf, who was so gentle that he trusted her to play with his children. And she was not the only one. There are many accounts of socialized wolves that were very gentle with people. Not all imprinted wolves are extremely emotionally reactive and predatory animals. It is true that most imprinted wolves exhibit these behaviors, which is why we are so strongly warned against keeping them. But there have always been very docile wolves.
Dalziel is merely showing his Victorian racial views. The “Red Man” of Canada couldn’t domesticate a wolf. Only Westerners could ever do such a thing.
But he really shows his error in that last line when he says that hybrids between wolves and dogs cannot breed. Of course, wolf and dog hybrids can reproduce. The two animals are now considered to be the same species, and as such, calling them wolf hybrids is no longer valid. The word hybrid denotes the breeding of two distinct species, and that is no longer the case when one discusses the breedings between wolves and dogs. This blog calls wolves “wild Canis lupus” and dogs “domestic Canis lupus.”
Dalziel also though Garry’s proportions all wrong, simply because they are all wrong for a sled dog.
But let’s look at what Garry’s proportions actually say:
Height at shoulder, 2ft. 6in.; length from centre between shoulder blades to centre between ears, 1ft.; from latter point to end of nose, 11in.; length from shoulders to setting on of tail, 2ft. 7in.; length of tail, lft. 4in.; measurement round head just behind ears, 2ft.; just above eyes, lft. 8in.; at point of nose, 10in.; his girth measured fairly tight, not outside the hair, 3ft.; his weight is 8st. 8 lb. His hair is long, straight, and pure white, which is his chief beauty.
Garry stood 30 inches at the shoulder and weighed 120 pounds (that’s how you convert from stones to pounds!)
That would make him a large wolf, not unlike an arctic wolf or perhaps an unusually large “Buffalo wolf” of the Canadian prairies.
No Canadian Eskimo dog (qimmiq) has these proportions. According to the breed standard, they are not to exceed 88 pounds and 28 inches at the shoulder. Qimmiq do look like wolves superfically, but because they have been bred for hauling, they are built very differently– much more bone and much broader chests.
W.D. Drury depicts anther “Esquimaux dog” that was a contemporary of Garry in British Dogs, Their Points, Selection, And Show Preparation (1903). Myouk was derived from dogs brought over by Sir John Franklin, and it is very obvious that he was a genuine article qimmiq:
Drury also takes exception with the notion that Garry could not have been a wolf or wolf hybrid:
Garry…was of a different type from many other Esquimaux that have been exhibited. He was sometimes called a North American Wolfdog, and was said to be a cross between a wolf and an Esquimaux bitch. It is a perfectly well-known fact that the wolf and dog will breed freely together, and the late Mr. Bartlett, of the Zoological Gardens, told the writer that the offspring will continue to breed – a fact that has been doubted by some [like Hugh Dalziel].
In addition to his different proportions from the qimmiq, Garry also appears to have larger feet in proportion to his body size than one typically sees in a dog. Northern wolves have large feet, which they use as snowshoes. They distribute the weight of the wolf out over the snow more evenly, preventing them from breaking through the crust and becoming encumbered. Sled dogs have similar feet, but they are not nearly as well-developed as those of wolves, which also have no sweat glands to produce moisture that will collect snow as the animal traverses snowy ground.
There is also quite a bit of evidence of indigenous people keeping wolves as pets. As a young boy traveling to the Canadian arctic as an assistant to his renowned ornithologist uncle to the artic of Manitoba, Farley Mowat encountered a native trapper with a live wolf pup. He implored his uncle to buy it, but he refused. The trappers wanted the bounty value for the pup– only $5– but his uncle seemed to think that such an animal would only cause trouble. It is possible that Garry or his ancestors had been collected in the same fashion.
Everything about Garry suggests that he was a wolf or high content wolf hybrid that was exhibited as an “Esquimaux dog.” Compare the depiction of Garry with these arctic wolves:
The resemblance is uncanny.
Garry was a show wolf or high content wolfdog.
From the LA Unleashed Blog:
Mexican researchers said Wednesday they have identified jawbones found in the pre-Hispanic ruins of Teotihuacan as those of wolf-dogs that were apparently crossbred as a symbol of the city’s warriors.
The National Institute of Anthropology and History said the jawbones were found during excavations in 2004 and are the first physical evidence of what appears to be intentional crossbreeding in ancient Mexican cultures.
The jawbones were found in a warrior’s burial at a Teotihuacan pyramid. Anthropological studies performed at Mexico’s National Autonomous University indicate the animal was a wolf-dog.
“In oral traditions and old chronicles, dog-like animals appear with symbols of power or divinity,” said institute spokesman Francisco De Anda. “But we did not have skeletal evidence … this is the first time we have proof.”
Wolf- or dog-like creatures appear in paintings at Teotihuacan, but had long been thought to be depictions of coyotes, which also inhabit the region. But archaeologists are now reevaluating that interpretation.
Several jawbones were made into a sort of decorative garment found on the warrior’s skeleton at the 2,000-year-old site north of Mexico City.
The wolf-dog apparently served as a symbol of strength and power.
Dogs and wolves are very similar genetically, and there has been evidence of ancient remains that may show natural crossbreeding.
But archaeologist Raul Valadez said the animal was the result of intentional selection. While the inhabitants of Teotihuacan had dogs, wolves and coyotes, they almost exclusively used wolf-dog bones in the ceremonial arrangement.
Of the bones found, eight were wolf-dog, three were dogs and two were crosses of coyotes and wolf-dogs.
These wolves would have likely been Canis lupus baileyi, which is now extinct in the wild in Mexico. They were actually known to hybridize with domestic dogs as the subspecies became rare in the wild. A whole line of these wolves that was kept at Carlsbad Caverns was euthanized under the suspicion that they were “contaminated” with dog blood. However, it was later found that these wolves had no evidence of dog hybridization in their MtDNA sequences.
This is yet another example of a gene flow between wild and domestic populations of Canis lupus, although the exact wild nature of these wolves is certainly in question. It is possible that these wolves lived in a state of semi-domestication. Historically, it hasn’t been very hard to habituate wolves to people, and it wouldn’t be very hard to breed an habituated wolf to a dog.
Or maybe they were urban wolves, like this one in Romania. Because there is no evidence of these people persecuting the wolves, they would have had more reason to hang around the city and have opportunities to breed with dogs.
The people of Teotihuacan were fairly good animal keepers. There is evidence that they were adept at keeping pumas and jaguars in captivity, so it would not be all that strange that they kept both wolves and coyotes in this manner.
Throughout their long history, dogs have retained some of their genetic diversity through wild blood. Now that wolves have been pushed very far from human societies,and dogs have undergone extensive selective breeding, these differences seem much more extreme than they once were.
But through much of that history, dog and wolf have bred with each other–sometimes intentionally, as seems to be the case here, and sometimes accidentally, as is likely the case with the evolution of black wolves in North America.
These ancient Mexicans worshiped the dog and the wolf. The hybrid was likely much like the character they lauded in the warrior. The warrior was civilized in his manner during times of peace and as savage as a wild animal in times of war. That dichotomy was celebrated when these hybrids were used for these ceremonial arrangements.
Perhaps one could find evidence ancient North American dogs were actually hybrids. It was suggested that the domestic dogs kept by various peoples of the Southeast were nothing more than tamed red wolves. Black red wolves were very common, which is why they had the archaic scientific name Canis niger.
However, all the studies I’ve seen suggest that New World domestic dogs from both the Pre-Columbian and modern era have predominantly or entirely Old World ancestry.
More work needs to be performed in examining the genetics of these New World dogs.
The intentional hybridization of Mexican wolves and domestic dogs at Teotihuacan shouldn’t be a surprise to anyone. We have evidence of wolf hybridization in the origin of certain Finnish and Scandinavian breeds. To find archeological evidence of hybridization in Mexico is just more evidence that dogs and wolves do not represent distinct species.
They represent the beautiful and wondrous diversity that is the species we call Canis lupus. From two-pound chihuahuas that fit nicely in handbags to giant bone crushing wolves that lived in Alaska during the Pleistocene, this species has had the ability to occur in some many different shapes and sizes.
The people of Teotihuacan were probably a little amazed when their domestic bitches bred wolves and produced puppies. Such a crossbreeding from such different looking animals would have been fascinating– almost to the point that it would have required a divine explanation.
And once that explanation would have been put in place, it wouldn’t have been very long before some priesthood would come up with a need to use them for ceremonial purposes.
According to Art Daily, some of the remains are from dog-coyote hybrids and to crosses with wolfdogs and coyotes, so intentional wolf and dog crosses were not the only Canis hybrids these people were creating for this purpose.
I strongly disagree with the suggestion in the Art Daily piece that pumas (cougars) are more easily domesticated than wolves. We have no domesticated cougars, but we have hundreds of millions of domestic dogs throughout the world. Not all wolves become status seeking machines in captive situations. Adolph Murie had one named Wags that was basically a golden retriever in wolf form.
The dog in “identify the canid” query from a few days ago is a Saarloos wolfhond. (In Dutch, it is “Saarlooswolfhond.” In English, it is sometimes called “Saarloos Wolfhound.”)
It is not a “wolf hybrid” or “wolf dog,” as we typically understand them. Most wolf hybrids and wolf dogs are the result of rather haphazard crossing wolves with GSD’s, huskies, and Malamutes.
This particular dog is part wolf, but it has been selectively bred to be a relatively tractable animal. Saarloos wolfhonds have even been used as guide dogs for the blind, and they are known for having relatively low levels of aggression towards people.
They are the result of a Dutch German shepherd dog fancier named Leendert Saarloos thought the GSD was a doomed breed. Many of the dogs were dying of distemper, and they were losing their guarding abilities.
To solve this problem, Saaloos began breeding his GSD’s with wolves, including some Canadian wolves. He then began to breed them to be more like dogs.
However, most of the dogs were very susceptible to distemper. Most of the original dogs in his breeding program died.
And the dogs were useless as guard dogs.
However, fanciers became interested in them in Germany and the Netherlands, because people thought it was awesome to own a dog that had some wolf in it. It was believed that German shepherds were very close to wolves, and owning a dog that was part wolf and shepherd was a way of reconnecting to those “wolf dogs of the Rhine” that Tacitus wrote lived among the Germanic tribes.
Although I am opposed to keeping casually bred wolfdogs, I am not opposed to keeping this breed or the similar Czechoslovakian wolfdog. These animals do have wolf in them, but they have been selected to be more like dogs. They are not as unpredictable as casually bred wolf-hybrids can be.
However, I don’t think either of these breeds should be kept by owners who don’t understand dogs very well. These dogs need mental and physical exercise and respect as “canine beings.”
