How to Train a Puppy That Bites
Puppies spend a great deal of time playing, chewing and investigating objects. All of these normal activities involve puppies using their mouths and their needle-sharp teeth. When puppies play with people, they often bite, chew and mouth on people's hands, limbs and clothing. This kind of behavior may seem cute when your puppy is seven weeks old, but it's not nearly so endearing when he's three or four months old-and getting bigger by the day!
What to Do About Puppy Mouthing
It's important to help your puppy learn to curb his mouthy behavior. There are various ways, some better than others, to teach this lesson. The ultimate goal is to train your puppy to stop mouthing and biting people altogether. However, the first and most important objective is to teach him that people have very sensitive skin, so he must be very gentle when using his mouth.
Bite Inhibition: Teach Your Puppy to Be Gentle
Bite inhibition refers to a dog's ability to control the force of his mouthing. A puppy or dog who hasn't learned bite inhibition with people doesn't recognize the sensitivity of human skin, and so he bites too hard, even in play. Some behaviorists and trainers believe that a dog who has learned to use his mouth gently when interacting with people will be less likely to bite hard and break skin if he ever bites someone in a situation apart from play-like when he's afraid or in pain.
Puppies usually learn bite inhibition during play with other puppies. If you watch a group of puppies playing, you'll see plenty of chasing, pouncing and wrestling. Puppies also bite each other all over. Every now and then, a pup will bite his playmate too hard. The victim of the painful bite yelps and usually stops playing. The offender is often taken aback by the yelp and also stops playing for a moment. However, pretty soon, both playmates are back in the game. Through this kind of interaction, puppies learn to control the intensity of their bites so that no one gets hurt and the play can continue without interruption. If puppies can learn how to be gentle from each other, they can also learn the same lesson from people.
When you play with your puppy, let him mouth on your hands. Continue play until he bites especially hard. When he does, immediately give a high-pitched yelp, as if you're hurt, and let your hand go limp. This should startle your puppy and cause him to stop mouthing you, at least momentarily. (If yelping seems to have no effect, you can say “Too bad!” or “You blew it!” in a stern voice instead.) Praise your puppy for stopping or for licking you. Resume whatever you were doing before. If your puppy bites you hard again, yelp again. Repeat these steps no more than three times within a 15-minute period. If you find that yelping alone doesn't work, you can switch to a time-out procedure. Time-outs are often very effective for curbing mouthing in puppies. When your puppy delivers a hard bite, yelp loudly. Then, when he startles and turns to look at you or looks around, remove your hand. Either ignore him for 10 to 20 seconds or, if he starts mouthing on you again, get up and move away for 10 to 20 seconds. After the short time-out, return to your puppy and encourage him to play with you again. It's important to teach him that gentle play continues, but painful play stops. Play with your puppy until he bites hard again. When he does, repeat the sequence above. When your puppy isn't delivering really hard bites anymore, you can tighten up your rules a little. Require your puppy to be even gentler. Yelp and stop play in response to moderately hard bites. Persist with this process of yelping and then ignoring your puppy or giving him a time-out for his hardest bites. As those disappear, do the same for his next-hardest bites, and so on, until your puppy can play with your hands very gently, controlling the force of his mouthing so that you feel little or no pressure at all.
