vet had no idea allergy cause Vet said he had no idea what caused the allergy but gave Buddy an antibiotic shot because it was a bacterial infection caused by allergies and recommended Royal Canin Hypoallergenic Hydrolized Soy protein food. My instinct is that it is more seasonal allergy or yeast infection as he just treated Buddy's ear for a yeast infection, which cleared up. I havent changed Buddy's food so I dont think that is the problem. |
