Well, I stopped by the vet this evening and they took Zahra in the back immediately when I showed the vet tech her fur that is coming out. They were closing but took her back and tested her anyway and sure enough she has mange. I don't know how I could have missed even thinking that, here I am thinking that she is rubbing from her collar or that Chase is play biting to rough with her.
Has anyone else had an experience with mange? Of course even thinking about it I feel like I have bugs crawling all over me. Zahra is on some meds for the next three months and the vet said that I caught it in a very early stage.
