My male yorkie recently has a bald patch just under his neck on his back. I noticed it the other night after his bath. It is about the size of a half dolloar and it down to the skin. It is the same spot that I generally give him his flea meds but I haven't started that this year yet. I took him to the vet Wed, and the vet was perplexed as well. He plucked some hair samples from Sammie and said he wouldn't have any results back for a week. Other wise he was healthy. I haven't seen him sratching but have seen him rub along the bottom of our couch, but not very many times. He is eating and drinking ok, going potty ok, I just don't know what is causing his hair to fall out in just that spot....Has anyone experienced this before? Any suggestions or advise is greatly appreciated. Thanks
Sandy and Sammie
