Puppy biting!!!?

What you need to try is what some trainers will teach you in obedience cles. When the pup does something that is inappropriate or wrong, you need to turn the dog over on it's back, wait for him/her to stop struggling (submit) grab his/her snout and make him/her look you in the eye and tell him/her "No biting" in a VERY stern voice (not yelling). Puppies don't understand what hurt and what doesn't or what is appropriate and what is not. You need to teach them that, and they need to know that YOU are the boss. Try this. It worked for my 3 male dogs. Good luck.
