Bite Inhibition

Bite Inhibition -- an Essential Part of Socialization

Dogs must learn to use teeth properly as part of behavior development. By helping dogs learn bite inhibition early on, you can help avoid bite incidents involving other dogs as well as people. This tipsheet contains information adapted from articles by Dr. Ian Dunbar in the November 1999 "Whole Dog Journal" and by September Morn in the April 2003 "DogFancy."

Puppy biting Tip:

Some have hard mouths, some soft, but they all do it while they are teething. This is what I do with my mouthing pups. I use a wash cloth, not a toy, as a toy represents play, and play represents biting. (For teething I use a frozen wash cloth) I put the pup on my lap and start petting her. As soon as she starts mouthing, I put the wash cloth in her mouth and she goes to work on that, while I continue to get her use to my touch in a gentle way. What I am saying is this "mouth and nip this, not me". I continue rubbing, scratching, and loving her all over with a very gentle hand. This gets her use to my touch without biting me. My goal in doing this is to get her to relax into my gentle touch, let go of the wash cloth, and fall asleep, which happens quite often. It also teaches her that my gentle loving hands are a place to come back to when she wants to rest and be loved. Teach your pup gentleness and she will give you gentleness.

Dogs normally learn bite inhibition by 4 and a half months of age. Dunbar believes it's the single most important thing that dogs learn. So try to teach your dog bite inhibition by age three months and reinforce throughout their lives.

Bite inhibition is a learned response in which the dog consciously inhibits the full force of his biting ability. Most dogs display bite inhibition when they are playing together, and even when engaging in a fight with another dog. If a dog does not have bite inhibition, he could injure and possibly even kill another dog.

Puppies who are properly socialized learn bite inhibition while nursing and playing. When pups bite while nursing, the mother dog will train them by standing up and walking away. When pups bite too hard during play with siblings, the bitten pup will yelp and stop playing with the rough pup. Or the bitten sibling might leap up and knock the rough-housing pup over with a loud bark or growl. This teaches a puppy that playtime ends if he bites too hard.

This is one reason puppies should go to puppy kindergarten or socialization class, where they can play and mouth while carefully supervised. They will learn that while gentle bites might be tolerated, hard bites will stop the play session.

People can use the same idea to teach their puppies bite inhibition.

* Sit down with the pup to play, bringing his attention to your hands. When the pup tries to bite your hand too hard, yelp or say 'Oww' firmly and stop interaction. In addition to stopping interaction, some canine specialists advise to pull your hands back and freeze, and to avert your eyes or look to the side, away from the pup.

* Do not make your response sound like wincing or whining, or the pup may think it's part of the game. The pup needs to learn that fun stops when he bites.

* Give the pup a toy to chomp on instead of your hands or clothing. If he does not take the toy and instead nips again, stop interacting. Turn away, cross your arms, do not look can even walk away.

* After time has passed, face your pup again and offer your hand. If he tries to bite, repeat the process.

* When your pup is gentle, pet and praise him calmly and resume play.

* If he bites again, say "Oww" as you did previously, and give him a 10-minute time-out. Leave the room, or better yet, place your pup in a time-out area. This area can be a separate room with no people or animal occupants, or in his crate. But avoid making this action seem like punishment -- you do not want the pup to learn to fear the crate or associate it with punishment. Time out is not the same as punishment. It is a suspension of playtime and fun.

* As you practice, the pup will use less and less pressure as he comes in contact with your hand.

* Keep in mind that the first goal is to teach the dog to actively inhibit the force of his bite, and THEN reduce the frequency. If you never let the pup put his jaws on you at all, when it does happen (say, an accident during which the dog's paw gets stepped on), the dog will probably react with an over-strong bite.

* Do not tap or smack the dog's nose as punishment for nipping -- instead of discouraging nipping, this tends to trigger instinctive biting in self-defense.

* Do not tease a pup or dog by flashing hands around his face or tapping his face. This can scare or startle the dog and trigger biting behavior, whether in play or self-defense.

* However, as the bite inhibition training progresses, you can gradually begin to incorporate some sudden movements into your play with the dog so he learns to be less spooked by human movement. If a dog is afraid of objects, you can help desensitize him by slowly incorporating hand-held objects into play.

* Daily grooming helps a dog get used to human touch. Teach your pup early on to allow you to touch his face and open his mouth. This will prepare him for activities like vet exams and tooth brushing. Start by gently raise the dog's lip and praise. You can also give a treat. Gradually lift the rest of his lip and examine the inside of his month.

Dunbar explains that no matter how hard you try to socialize a dog to people or other dogs, there may be times when it is not sufficient. For example, someone shuts the dog's tail in a door, or your dog is attacked by another dog. In these cases, your dog will instinctively respond by biting, whether it's out of provocation or self-defense. Whether or not your dog does damage depends on the level of bite inhibition that was established, usually before he reached age four and a half months.

Bite inhibition can be taught to a dog later in life, but it is more difficult and time-consuming. You will want to be prepared to avoid and control problems that may arise.

Dunbar believes that if a dog does not have bite inhibition, the dog should be muzzled when walking in public areas. Even if another dog starts a fight, your dog will be blamed if his bites cause damage.

Dunbar recommends the open-ended muzzles of soft but strong fabric, usually nylon, that control biting but are open in the front to allow the dog to drink, lick his lips and accept a treat. The goal is to train the dog to enjoy the company of other dogs, and to behave appropriately ... meaning sit, settle down, and be calm. So if a muzzle is used, choose a style that enables the dog to take treats.

Even using a muzzle, you must be fully vigilant. If you have or come into contact with other dogs, and you allow a dog to bite your muzzled dog, you will only reinforce in his mind that the other dogs should be bitten. So in training the dogs to get along, Dunbar advises muzzling your other dog(s).

Dunbar suggests these simple exercises to condition the biting dog to associate the presence of another dog with good things, not bad things:

* Put the biting muzzled dog on a leash, and sit down on the sofa, petting the dog. Have someone else enter the room with the other muzzled dog, and then leave after a few moments. Have the other dog and person repeatedly enter and leave the room.

* Give the biting dog two types of feedback. When the other dog leaves, totally ignore him. When the other dog enters, praise your dog and offer him pieces of kibble and perhaps treats, even if he’s growling and putting his hair up.

* Remember, the growling does not exist on its own. The dog is growling for a reason. If you give him a piece of kibble when the other dog comes in, you are classically conditioning the dog to form a positive association with the other dog’s entry and presence.

* Eventually, the dog will form a positive association about the other dog and should, over time, stop growling because he will realize he has no reason to growl. "I don't particularly like that dog, but I love it when he comes into the room, because my owner talks to me, pets me, and gives me kibble." Timing is key, of course.

* For the next step, do the same exercise, but with the positions reversed. The other dog is in the room, and you enter and exit with the biting dog, giving him treats when you enter the room, and ignoring him when you leave.

* Do not yank on the dog's leash or spank him or yell. If you constantly reprimand the dog whenever another dog is present, you will reinforce your dog’s negative feelings for other dogs. The dog will learn that when other dogs approach, his owner gets upset, sweats, her heart rate increases, and she shouts and jerks the leash. So the dog gets the wrong idea and thinks he needs to keep other dogs away. He sees another dog and says, "Get away, get away, and don’t come close! My owner is unreliable around other dogs!"

* That is why it is important to not punish the dog. Instead, teach him acceptable behavior and continually reinforce your role as a leader who he can and must trust.
