What are you feeding him?
Peanut had the same symptoms. He would get hot spots, red splotches, red ears, licking paws, chewed all his leg hair off and etc. I had to give him a Benadryl as well as cortisone cream daily. We went through so many foods and the only thing that fixed him was switching to Canine Caviar. I know it sounds crazy.. how can a kibble fix those symptoms, but it’s true. It took about 2 months for us to stop all medicines. In our worst allergy months he has no signs. I would highly recommend Canine Caviar to any dog that has food allergies.
One of the medicines that really helped Peanut was the Neo Poly Dex. I would put this on his hot spots and red splotches and it would really help clear it up.
