My wife and I have a 4 month old male papillon and he keeps tearing (digging/chewing) up his puppy training pad that I tape down in his room (bathroom). We leave him plenty of toys, his puppy, 2 squeaky toys. Could it be his nails are sharp, or is he just bored? I caught him donig tonight and swapped him and told him NO Bad dog. Any other advice would help.
