My pit bull puppy (8wks old) likes to bite and chew on toes and fingers.I know its playful, but her teeth are super sharp and they hurt.. not to mention its not a good habit for her to get into. i know she's teething or whatnot, but im trying to get her to stop. Right now my fiance and i are trying two things.. When she bites and starts chewing on us we tell her "no!no!" and lightly tap her nose w/ our finger... Or We put our fingers in her mouth and say "easy" So far, she's pretty determined to keep chewing..
