Ok well for the last few weeks I noticed my new puppy has been scraching and bitinh her self alot. Righ now she has black fur but I can see a new redish colored coat coming in. She has patches of fur missing on her ears. Is her fur coming out so the new coat can come in? OH! Last night I was petting her and I kind of took a little of her fur by her ears and pulled, the fur came right out. I didn't pull hard and she didn't yelp or anything else to indicate I had just pulled a toft of fur from her head. Could you please help? I cannot take her to the vet until next week (when we go to get her final shots).
