How To Stop Puppy Nipping & Biting: Why Do Puppies Bite? When Do They Stop Biting?

All puppies nip or bite at your hands, fingers, toes, feet, and ankles.

But there’s one big reason that you should not allow this behavior anymore.

Here’s how (and why) to stop a puppy from nipping and biting…  

Why Do Puppies Bite?

All puppies nip and bite. It’s usually not so much of a behavior problem as it is a natural, normal part of growing up.

Puppies bite and nip at people for these reasons:

  • As a way to play with other dogs and people.
  • As a way to establish dominance around other dogs and people.
  • As a way to make their gums feel better when they’re teething.

When puppy nipping and biting continues, it’s a dog’s way of attempting to “feel you out” in the moment and determine how much they can get away with (…aka how much of a boss dog they are).  

The #1 Reason To Stop Puppy Biting

While all puppies nibble and bite on your hands, your ankles, and everything else they can get their mouth on… you should not allow your puppy to nip and bite you (or other people) for this one reason:

Puppy biting says, “I’m more dominant than you!”

Nipping and biting at a person’s hand is the dog’s way of testing their dominance in the pack. (Yes, you are part of your puppy’s “pack” now.)

Since there should never be any question that YOU are the Alpha dog in your household, from this day forward you must never allow your puppy to nibble or bite at your hands or feet after you’ve told them NO.

To stop your puppy from nipping or biting, do this:

  1. Use your thumb and forefinger to roll the puppy’s top lips under his teeth — so that he bites down on them.
  2. The puppy will whimper after he’s bit his lip.
  3. At the same time, boldy say “NO!”

The trick is consistency. From now on, you should never let your puppy nip at you or other people. It won’t take long before your puppy gets the message. (This is called Bite Inhibition Training.)

Stop your puppy from nipping by covering your hand with peanut butter and letting it lick it off. This trains it to associate licking with the hand, not nipping. Never hit the dog’s nose or mouth.

When Do Puppies Stop Biting?

When do puppies stop biting? Find out here!

Puppies stop biting and nipping after they’ve lost all their baby teeth and have their full set of adult teeth — which is around 6 or 7 months of age.

Puppies start teething (chewing and gnawing more) to soothe their sore gums while their adult teeth are coming in.

Here’s what you need to know about puppy teeth:

  • Puppies have 28 temporary teeth (or puppy teeth).
  • A dog’s puppy teeth start coming in between 3 and 4 weeks of age.
  • A dog’s puppy teeth fall out between 14 and 30 weeks of age.
  • A dog’s adult teeth are fully in place by 6 or 7 months of age.
  • Adult dogs have 42 permanent adult teeth.

Rest assured, as long as you’re patient and continue to give your dog consistent reminders every time your puppy keeps biting or nipping at you… they will, indeed, eventually outgrow this annoying behavior.

Once they’re done teething and have lost all of their puppy teeth, your dog won’t have the same urge to nip and bite all the time. And by this time, your pup should understand your training cues that say the nipping and biting behavior isn’t acceptable.  

The Bottom Line

Although your puppy will grow out of the nipping and biting phase by the time they reach 7 or 8 months old, it doesn’t happen naturally.

It takes patience and a LOT of Bite Inhibition Training!

The earlier you start this training, the better. It’s one of the very first behaviors that you should focus on when training your new puppy. (That and housebreaking.)
