The dogs above are two purebred Labradors, and the white spots you see on the coats are not the result of the distortion or aging of the photo.
They actually are black dogs with what might be called “reverse Dalmatian spots.”
This coloration is quite rare in Labradors, and because of its rarity, no one knows its genetic basis. It just occasionally pops up in Labrador litters.
Countess Howe, one of the major forces behind the modern Labrador retriever breed, called this color “hailstone.”
A very similar color also pops up in greyhounds, where it is much more common.
I have tongue-in-cheek called this coloration “ich” (pronounced “ick.”)
If you don’t know what “ich” refers to, well, there is a condition that occurs in freshwater fish called “ich.”
The official name for the disease is called Ichthyophthirius multifiliis, but most aquarists shorten it to “ich.” It is also called “white spot disease,” because it is easily recognized when one sees small white flecks on the gills and body of an aquarium fish.
The disease is caused by a protozoan called Ichthyopthirius that establishes itself on the body of the fish. Each white fleck is actually where a protozoan has set up a residence. These parasites wind up damaging so much of the skin and gill tissue that the mortality rate from fish affected by the disorder is quite high.
Of course, these dogs aren’t affected by anything other than some novel color phase.
It just happens to remind me of the deadly fish disease.
However, looking at these Labradors, I’m sure many will be reminded of the old cartoon 101 Dalmatians, where at one point, the Dalmatians try to sneak past Cruella de Vil and her minions, Horace and Jasper, by rolling themselves in soot and trying to pass themselves off as Labradors. Everything goes according to plan, until melting snow hits the dogs’ coats, revealing that they are Dalmatians and not Labradors.
(BTW, if you can’t tell the difference between a Labrador and a Dalmatian that is dyed black, there is no hope for you!).
