interesting. at what age do they turn the more typical red color? The color change is more typical of say, “fawn” (ay gene) color changes than what I’ve heard about the red/liver (e gene) in dogs. It would be interesting to know if the genes are the same or different or if the same gene has different expression in this species (some of the color genes seem to be very consistent in very different animals such as red/black in cattle, and some seem to be specific to canis. The different colors in less related canids is interesting — for example, I don’t think there’s ever been a fox colored wolf (complete with tail tip, etc) and the “wild dog” calico clearly isn’t merle.
Scott, do you know whether canids of any species have any thermal-influenced colorations, such as is found in Siamese-patterned cats? I have researched this and have not found any references to canids with this type of coloration, although thermal-restricted color patterns appear in mice, guinea pigs, rabbits, and some other species. Many coat colors and patterns in canids change as the animals mature, but as far as I can find, none of those changes are thermal-influenced.
I don’t know of any colors in dogs that are like that. That particular type that you mention is very common in different species of domesticated rodents, guinea pigs, and mice have it. Domestic rabbits have it, too, though they are not rodents.
