I have a question that may sound strange, but is any amount of scratching considered normal? I have Bentley on wet and dry chicken soup. I notice that he mostly scratches when he 1st gets up, right before he goes out and some times he will lick himself at night before going to bed. I know food and shampoos are trial and error and some can be inhalant allergies, but I wanted to know if any itching is considered normal? Thanks so much for all the great info you all share!
