When do puppies start and stop teething?

Puppies are born without teeth. Baby teeth (28 total) come in between 3–6 weeks. The teething phase that owners notice most — when puppy teeth are falling out and adult teeth are erupting — happens between 3 and 6 months of age. By 6–7 months, most puppies have their full set of 42 adult teeth and the intense chewing drive usually subsides.

Is it normal for puppies to bleed when teething?

Yes, small amounts of blood on chew toys are normal during the baby-tooth-loss phase (3–6 months). You may also find tiny teeth on the floor or notice your puppy swallowing them — both are normal. Contact your vet if you see heavy bleeding, significant swelling around the gums, or if adult teeth appear to be growing in abnormal positions alongside retained baby teeth.

How do I soothe a teething puppy?

Cold and frozen items are the most effective relief — frozen carrots, frozen wet washcloths, or commercially made teething toys that can be frozen. The cold reduces gum inflammation. Provide multiple appropriate chew items so your puppy always has something acceptable nearby. Rotate toys to maintain novelty. Puzzle feeders and Kongs stuffed with frozen food also provide satisfying chew sessions.

Why is my puppy biting more during teething?

Chewing relieves the pressure and discomfort of erupting adult teeth. It is an involuntary response to gum pain, not disobedience. Provide abundant appropriate chew options and redirect immediately when biting humans. The intensity typically peaks around 4–5 months and resolves by 6–7 months as adult teeth settle. Consistent redirection now builds habits that last after teething ends.
