I have had pick puppy also. Not an issue, but just seeing ALOT more in pictures than we ever have. Coming down from something we are all using. Seeing more in blacks, can't tell yellows and not lately in choc. No big deal.
I just kept a yellow pup; who has some white on her rear toes. she has awesome conformation, temperament, moves like a dream, and a perfect eye clearance, EIC/PRA clear by parentage. a few white hairs no big deal!
