It looks like my dog is hurting himself. He’s scratching his head so hard he’s cutting it, hes rubbing his paw on his teeth, and biting his paw. My doberman recently died. My rotti has been kind of depressed and now he’s doing this. The rotti is 2 and the doberman was 5 so the rotti grew up with him from when he was 8 weeks old. Why is he doing this?
