I don't know if this is actually a "Vet" question, but Lizzie has white hairs scattered around in her coat. Not in clumps, just one hair here and there. The hairs seem to not be strongly attached to her skin. If I am able to single out one of them, I can pull it out with my fingers. I wonder if they could be the result of scar tissue, maybe from fleas or bites from another dog. Has anyone seen this before?
