Why puppies mouth
Puppies explore the world with their mouths. Littermates also teach each other bite limits: bite too hard and play ends with a yelp. Labs were bred to carry game in their mouths, so many are especially mouthy. Teething from about three to six months adds to the urge to chew.
This is not aggression. It is normal development, and your job is to teach what is allowed.
Step 1: Give your puppy appropriate things to chew
Keep a variety of toys within reach: rubber chew toys, rope toys, a frozen wet washcloth for sore gums, and puzzle toys stuffed with a little food. Rotate them so they stay interesting. When teeth meet hands, offer a toy instead and praise your puppy for taking it.
Step 2: Pause the fun when teeth touch skin
When your puppy bites too hard, say a calm "ouch" or "oops", stop moving and take your hands away. If the biting continues, stand up and step away or calmly place your puppy in a pen or crate for a minute or two. Return when calm. The message is simple: teeth on skin ends the play.
Avoid yelling, flicking, holding the muzzle shut or "alpha rolling." Those techniques scare puppies, can damage trust and often make mouthing worse.
Step 3: Reward the right behavior
Catch your puppy being gentle. When they lick, sit or play with a toy, praise and treat. Teach "sit" for greetings so they have something to do besides jump and nip. Short training games a few times a day tire puppies out mentally and teach impulse control.
Step 4: Exercise and sleep
An overtired or under-exercised puppy is a biting puppy. Labs need a lot of sleep, often 18 hours a day, and nip more when overtired. If your puppy turns into a gremlin in the evening, that is usually a sign it's nap time. Place them in their crate with a chew and let them settle. Balance this with short walks and play; see our Lab puppy exercise guide.
Step 5: Be consistent
Everyone in the house must follow the same rules. If one person lets puppy teeth slide during roughhousing and another does not, your puppy gets mixed signals. Explain the rule to children and guests, and supervise play with young kids.
What not to do
- Do not play tug or wrestle with hands as toys
- Do not let a puppy chew on you "just a little"
- Do not punish after the fact; puppies do not connect it
- Do not ignore the biting and hope it fades without teaching alternatives
When will it stop?
With consistent teaching, most Lab puppies are much calmer by five or six months, as adult teeth come in and impulse control grows. Some adolescent mouthiness may remain until around a year. Keep training and keep the exercise up.
When to ask for help
If a puppy shows true aggression, such as stiffening, growling over food or toys and biting hard with a hard stare, call your vet and a qualified trainer. That is very different from normal puppy mouthing. If you are one of our families, you are welcome to call or text us anytime.

A sample day of bite-free habits
Mornings: a short potty trip, a chew toy in the crate and a training game. Midday: a walk or sniff session, then a nap. Afternoon: play with toys, never hands, and one more short training session. Evening: a calm chew, a gentle wind-down and an early bedtime. Structure keeps puppies from getting overtired, which is when most hard biting happens.
Teething and what helps
Between about three and six months, puppies lose their baby teeth and chew harder. Cold helps: a frozen carrot, a chilled rubber toy or a wet knotted washcloth from the freezer can soothe sore gums. Avoid hard bones, antlers and nylon chews that are harder than a tooth, because they can crack teeth. If something is too hard to dent with your thumbnail, skip it.
Children and puppy biting
Kids often squeal and run, which puppies take as an invitation to chase. Teach children to stand like a tree, fold their arms and stay quiet until the puppy calms, or to toss a toy for the puppy instead. Supervise every interaction, and give your puppy a break in the crate or pen when they get overexcited. It protects the child and the puppy.
Bite inhibition
Bite inhibition means learning to control the pressure of the mouth. Puppies learn most of it from littermates, and we begin reinforcing it in our home before pickup. You are finishing the lesson. Reward softer mouths with praise, and pause play when it gets too hard. Over weeks, you will see the pressure soften and the biting fade into gentle, polite mouthing.
