- Starts biting when someone stands or walks away
- Repeatedly returns to skin after a toy is offered

Why do puppies use their mouths?
Mouthing is a normal part of exploration, play, teething and early social learning. The same behaviour can also signal overexcitement, frustration, fear, discomfort or the need for a break. Looking at what happened just before, during and after a bite helps you read the moment rather than guess.
What should you do when teeth make contact?
- Pause the interaction calmly without shouting, squealing or pulling hands away fast.
- Stand up or step behind a baby gate to create distance without grabbing, pinning or chasing.
- After a brief calm, offer an appropriate dog toy or chew and let the puppy choose to engage.
- Resume play or quiet attention when the puppy is calmer; end the interaction if biting returns.
Supervision, baby gates and a predictable routine do more than any single correction.
Is puppy biting normal or aggression?
Some mouthing is common, but a single bite description cannot diagnose an individual puppy. Consider the body tension, the bite intensity, the situation, and whether the interaction can be stopped safely. A stiff or frozen body, hard biting, repeated attempts when someone moves away, or guarding of food, toys or resting places are signals that warrant individual support.
How should biting be managed around children?
Adults stay close enough to step in and separate. Children are not expected to stop an actively biting puppy or test a training step. Use baby gates, playpens or separate rooms when active supervision is not possible, and avoid chase and wrestling games between children and puppies.
Common mistakes to avoid
Avoid scolding after the fact, forcing a hand into the puppy’s mouth, muzzle squeezing, scruff grabbing, alpha rolls, leash pops, or using a puppy’s crate as a punishment area. These methods do not explain what to do instead and can make mouthing worse or create new welfare concerns.
When should you ask for individual support?
Contact a veterinarian when biting appears suddenly, follows a health change or may be connected with pain. Seek a credentialed, reward-based behaviour professional when biting is escalating, difficult to interrupt, associated with marked tension or guarding, or involves fear inside the household. Confirm the professional’s qualifications and methods rather than relying on a job title alone.
The named sources support the general guidance; they do not diagnose an individual dog.
Observe the context, use manageable steps and adjust to the dog in front of you.
Stop ordinary practice when distress, pain or physical safety is a concern.
