my sister recently got a puppy he was cute and all untill he started to bite .
at first it was just playful biting and now when ever he is hypo he bites what ever is near him !
how can i or my sister stop him?
he never stops. from biting paper to biting ur pants and then even worse biting ur face when you try to lay down
he is currently 4 months old im not sure if it is just teething or if it is a habit
i tell him not to bite my fingers and when he does i grab his mouth ! but it doesnt stop him
please help me.....
its getting on my nerves
