Hi, my 8 month old male has been on a never ending scratching fest for the past few weeks. Nothing has changed as far as diet..etc. He constantly scratches himself and baby bites his skin with his front teeth. I know that dogs are prone to allergies, but have heard that can be hard to find out exactly what he is allergic to specifically. Has anyone had the same experience with their dog doing this? My husband thinks that he is just cleaning himself but it's definitely not.
