Why does my puppy bite more during play?

Puppies tend to use their mouths more when they get excited or when playing, as they often become overstimulated. Their developing brains aren't yet well-equipped to handle impulse control, so they express their energy through their mouths. Things that get them excited, such as playing or engaging in other high-arousal activities, bring them back into that instinctual behavior zone, which appears to peak during growth spurts and socialization periods.

Take into account the tendency of his breed when you consider a remedy for play-biting: herding groups such as Border Collies will chase and nip at legs during romp; retrievers will mouthing and holding on; terriers snap quickly. Adopt a method of prevention that fits your puppy's natural instincts, and it will be much more effective.

Consistency among all play partners is critical to preventing mixed messages. Children should learn that they may not mouth the dog until they fully offer a toy. Adults should avoid rough games that involve hand-wrestling, as this can encourage mouthing. Unified responses by all authority figures in the puppy's life make it clear that skin never equals a toy.

Puppies from larger litters are often slightly better at controlling their bite at first. With singleton puppies, you must provide extra redirection practice, as littermate feedback is not available. If, despite four weeks of consistent training, you find that play biting remains extreme, you may need to consult a professional about addressing fear or anxiety within the puppy's temperament.
