Hi, my labrador retriever had severe itching in his ears. He started with shaking and tilting his head and now he has ended up harming himself. His ears wax too much and smell even if cleaned everyday. Also there is itching on the neck region below the chin down to the chest. He is losing hair and skin has blackened in that area. The self harming tendency is increasing daya by day. We have tried systematic antibiotics, ear drops/cleansers, medicated shampoos but nothing seems to work. Please help. I feel terrible to look at my pup in this position.
