Amberleah goes for her 3rd shot today and I am having her right back leg looked at and her ears, also I notice her fur on her back is blotchy. She has a long dark patch of fur going down her spine and is spreading out and blotchy now. Maybe she is losing her baby fur. I am having it check out anyway while I am there. Since I am only giving 1/2 doses the vet wants her to have 1 extra shot. What do you think.
