8mo old BITING butt and hands social aggression, playful but getting worse
My 8 mo old male neutered shepherd nips and bites and it's getting worse. Here's what it looks like: Often when I'm walking he comes behind me and bites my butt and hands. It is more like an open mouthed lunge than a bits. He doesn't necessarily clamp down. However it can be painful with those sharp teeth. It is like he is being defiant and pkaying at same time. He KNOWS this is not acceptable behavior. I'm concerned because it's gettin worse not better. Yesterday my husband was cleanin somethin off the floor. Thor thought he was playing and did an open mouth lunge. His tooth hit my husbands eyebrow and made it bleed!!!
Here's what we've tried: pinch collar, muzzle shakes, ignoring (tough when he won't stop. Is ignoring appropriate for this?), negative experience of sticking fingers down throat, and wrapping hands around muzzle with firm "no", and redirecting him with a command and praising when obeyed.
Nothing seems to be making things better!!! Please help!!! Is this just a phase? I feel owned by my dog.
