I've had my Doberman since he was a puppy, I've always coddles him, and given him tons of attention. He has never hurt me, and has always been loving. Hes gotten all his shots, including his rabies shot. Last night I tried to hug him as usual, and he started growling, LOUD.MI figured maybe he had something he shouldn't,mbut he had nothing and he startd licking me and rolling over like he was sorry. I rub his belly, and then try to nestle into him, he barked loudly and Bit into my head. I punched him and shoved him off my bed refelxively and he slept on the couch. He whined at my door all night. Today (the next day) hes acting fine. I figured maybe it was me smelling like our other dog (we got her recently but he never seemed to mind her) but I have a feeling thats not it. This is very uncharacteristic of him. Whats wrong with him?
