Two weeks ago my dad bought a 2 month old miniature schnauzer. His name is Clauss and he's teething. We keep lightly bopping him on the muzzle and telling him no when he bites but that doesn't seem to be enough. Also, we bought those leather chew sticks for dogs to bite on but he doesn't seem to be that interested. All he does is try to bite us..not that hard just kinda nibble. But still, that's not very healthy for a puppy. So...what shall i do?
