 I am not a member, but I know much about dogs and wolves and am in training to be a vet. I don't think that the black pelt gene ""migrated"" into the wolf from dogs at all. I would say that it instead was a mutation by natural selection that appeared suddenly in wolves, and is now growing more common through wolves that have that gene mating with other wolves who have the same gene and the pups ending up with two of the black pelt genes, therefore making them black-pelted instead of the usual grey, red, or white pelts. I hope more people will see from my point of vision and try to understand that not everything that happens unnaturally in wolves comes from the dog."
