| Re: how do i stop 9 wk puppy from biting? I have a 4 month old Rotty, named Brad. He is learning now what No Bite means, My mom tryed to gently hold his mouth together and tell him no bite, someone suggested tapping him on the end of the nose. He doesnt really like biting on me its more or less everyone elses ankles. I think he will grow out of it, so I just tell him no bite and give him one of his toys. |
