At what age do puppies stop biting?

Puppies typically go through a phase of biting and mouthing as part of their normal development, and this behavior generally subsides as they grow older. Here are some key points regarding when puppies usually stop biting:

Teething Phase

• The peak of puppy biting often occurs during the teething phase, which starts around 3-4 months of age and continues until all the adult teeth are in, usually by 6-8 months of age345.

Bite Inhibition and Socialization

• Puppies learn bite inhibition through interactions with their littermates and humans. By around 7 months of age, most puppies should have learned to control their biting and have all their adult teeth, which marks a significant reduction in biting behavior135.

General Timeline

• Most puppies outgrow the biting phase between 5-7 months of age. By this time, they have usually learned to play with toys and appropriate chews instead of human skin235.

Consistency and Training

• Consistent training and clear responses from humans can help puppies understand that biting is not acceptable behavior. Even with proper training, some puppies may continue to exhibit biting behavior until they are a bit older, but it should significantly decrease by the time they are 6 months old135.

In summary, while the exact age can vary slightly, puppies generally stop biting excessively by around 5-7 months of age as they complete their teething and learn appropriate bite inhibition.
