Why is my puppy nipping and biting family members?
Although often thought to be a teething behavior, nipping, mouthing and biting in young dogs
is generally a form of social play.
Teething is more likely to involve gnawing or chewing on household objects. The first thing
you must do is provide ample opportunity for play, without biting. Social play with people
could involve controlled chase and retrieve games, as well as long walks or jogging.
Although wrestling and tug-of-war games can be fun, they may lead to play that is too rough or
Puppies need to learn to inhibit the force of their bite, commonly known as bite inhibition. This
is something they start to learn while with their litter mates. It is one reason that puppies should
not go to new homes until 7 - 8 weeks of age and they have had time to practice social skills
with other dogs. It can therefore be extremely beneficial for the puppy to have regular
interactive social play periods with other dogs or puppies in the home or in the neighborhood.
(See our handout ‘Play and exercise in dogs’ for additional information).
How can I stop play biting?
Provided the dog is receiving adequate play, attention and exercise, you can turn the training to bite inhibition. One of the
things that they need to learn is how much pressure from their jaws causes pain. Without this feedback, a puppy does not
learn to inhibit the force of its bite. Because all dogs can and will bite at some time, this lesson is vital for human safety.
How is this lesson taught? When puppies play with each other, if one puppy bites another too hard, the bitten puppy will
yelp, and may also stop playing and leave. This sends the message to the puppy that its' bites were too hard and if it
wishes to continue to play, it needs to be gentle. However, people often do not send this message to their puppy. In the
beginning, they often allow the puppy to chew on them without reprimands and the puppy assumes that the behavior is
acceptable. Children appear to be most vulnerable because their attempts at stopping the biting may not be properly timed
or sufficiently abrupt to stop the puppy from biting. In fact a child’s response is often seen by the puppy as an invitation to
increase its level of chase and play. Adult supervision or a head halter for training (discussed below) should help to insure
more immediate success.
The message people should send is that mouthing and chewing on hands is painful. To do this, often all that is necessary is
for all family members to emit a sharp ‘yip’ so that the puppy backs off and cease all play and attention immediately. This
sends the message to the puppy that the bites are painful and that biting will cause play to be terminated. When consistently
administered this will often stop playful biting. Another option is to use a sharp ‘off’ command while briefly pushing forward
with the hand to back the puppy away (no hitting). The command ‘off’ followed by the immediate removal of play can act as a
form of punishment with the word ‘off’ soon teaching the dog that if it continues to bite, play will be withdrawn. This training
often works for those family members that are a little more forceful and assertive and who are immediate and consistent in
their training. If the puppy persists, chases or immediately repeats the behavior, closing a door and walking out of the room
can help to teach the puppy that nipping leads to immediate inattention.
What if yelping does not help?
Other techniques are often suggested for play biting. Some involve harsh discipline, like slapping the puppy under the chin
or forcefully holding the mouth closed. Remember, pain can cause aggression and cause the puppy to become anxious,
fearful or perhaps more excited. These techniques also require that you grab an excited puppy; not an easy thing to do.
Some puppies may even misinterpret the owner’s attempts at punishment as rough play, which in turn might lead to an
increase in the behavior. Physical methods are therefore not recommended. Owners who cannot inhibit the puppy with a
yelp, could consider a shake can, electronic alarm, air horn, or ultrasonic device, as soon as the biting becomes excessive.
The use of a head halter with a remote leash attached allows the puppy to play and chew, but a quick pull on the leash can
immediately and successfully close the mouth and stop biting without any physical force. By simultaneously saying "no
biting", most puppies will quickly learn the meaning of the command. As soon as the puppy stops and calms down, the
owner can allow play to resume, as long as biting does not begin again. This is one of the quickest and most effective
approaches to stop the biting and get immediate control of the muzzle and mouth, for owners that are not gaining sufficient
Remember that play biting is a component of play behavior in puppies. Play is a form of social interaction. Realize that your
puppy is trying to play with you even though the behavior is rough. To ensure that you are in control, be certain that each
play session is initiated by you and not the puppy, and that you can end each session whenever you choose. One effective
strategy when the play gets too rough is to immediately end the play session and leave. Social withdrawal can be a very
powerful tool. Leave the puppy alone long enough to calm down. If upon your return the wild playing begins again, leave
again. Although it is tempting to pick the puppy up and take it out of the room, this interaction may be interpreted by your
puppy as additional play and the biting may continue as you carry the puppy to a confinement location.
