I have unfortunately had a yorkie puppy born grey, and it had "Colour Dilution Alopecia", all the hair that the puppy had left by 6 months old was the tans on the head. I didn't know it, at the time of mating, but my bitch was a carrier and also the stud dog.
What lines do you have in the pedigree of your puppy? Is the hair coarse and sparse? How old is your puppy? I hope your puppy does not have the same condition. |
