Forbidding a young puppy from biting altogether may offer immediate and temporary relief, but it is potentially dangerous because your puppy will not learn that his jaws can inflict pain. Consequently, if ever provoked or frightened as an adult, the resultant bite is likely to be painful and cause serious injury.
Certainly, puppy play-biting must be controlled, but only in a progressive and systematic manner. The puppy must be taught to inhibit the force of his bites, before puppy biting is forbidden altogether. Once your puppy has developed a soft mouth, there is plenty of time to inhibit the frequency of his now gentler mouthing.
Teaching your puppy to inhibit the force of his bites is a two-step process: first, teach the pup not to hurt you; and second, teach your pup not to exert any pressure at all when biting. Thus the puppy's biting will become gentle mouthing.
Teaching your puppy to inhibit the frequency of his mouthing is a two-step process: first, teach your puppy that whereas mouthing is OK, he must stop when requested; and second, teach your pup never to initiate mouthing unless requested.
It is not necessary to hurt or frighten your pup to teach her that biting hurts. A simple "Ouch!" is sufficient. If your pup acknowledges your "ouch" and stops biting, praise her, lure her to sit (to reaffirm that you are in control), reward her with a liver treat, and then resume playing. If your pup ignores the "ouch" and continues biting, yelp "Owwwww!" and leave the room. Your puppy has lost her playmate. Return after a 30-second time-out and make up by lure-rewarding your puppy to come, sit, lie down, and calm down, before resuming play.
Do not attempt to take hold of your pup’s collar, or carry her to confinement; you are out of control and she will probably bite you again. Consequently, play with your puppy in a room where it is safe to leave her if she does not respond to your yelp. If she ignores you, she loses her playmate.
Once your pup's biting no longer hurts, still pretend that it does. Greet harder nips with a yelp of pseudo-pain. Your puppy will soon to get the idea: "Whooahh! These humans are soooo super-sensitive. I'll have to be much gentler when I bite them." The pressure of your puppy's bites will progressively decrease until play-biting becomes play-mouthing.
Never allow your puppy to mouth human hair or clothing. Hair and clothing cannot feel. Allowing a puppy to mouth hair, scarves, shoelaces, trouser legs, or gloved hands, inadvertently trains the puppy to bite harder, extremely close to human flesh!
Once your pup exerts no pressure whatsoever when mouthing, then —and only then—teach him to reduce the frequency of his mouthing. Teach your puppy the meaning of "Off!" by handfeeding kibble (see the SIRIUSŪ Puppy Training video). Your puppy will learn that gentle mouthing is OK, but he must stop the instant you ask him to stop.
Puppy Must Never Initiate Mouthing
At this stage, your puppy should never be allowed to initiate mouthing (unless requested to do so). Please refer to our Preventing Aggression booklet for a detailed description of the essential rules for bite-inhibition exercises such as handfeeding, play-fighting, and tug-of-war.
By way of encouragement, mouthing-maniac puppies usually develop gentle jaws as adults because their many painful puppy bites elicited ample appropriate feedback. On the other hand, puppies that seldom play and roughhouse with other dogs, puppies that seldom bite their owners (e.g., shy, fearful, and standoffish pups), and breeds that have been bred to have soft mouths may not receive sufficient feedback regarding the pain and power of their jaws. This is the major reason to enroll your puppy in an off-leash puppy class right away.
