The vet thinks Nova has seasonal allergies. We have taken her in for rashes, itching, and yeast infections 3 times since January when we first switched over to this vet (my old vet was not a very observant one). He said if it returned again that he'd reccomend an allergy test, and that is what we are going to do. We have been applying medication to her paws for a couple weeks now and she quit chewing them, but now has started chewing her hocks. She's just so uncomfortable and is chewing herself raw. The bitter apple spray does squat to keep her from chewing.
