how old are dogs when they lose their baby teeth

Most puppies start losing their baby teeth at about 3–4 months old and usually have their full set of adult teeth by around 6 months of age.

Quick Scoop

• Typical start: Baby teeth usually begin to fall out around 12–16 weeks (3–4 months), often starting with the small front incisors.

• Main teething window: Most of the tooth loss and adult tooth eruption happens between 4–6 months of age.

• Mostly done by: By about 6–7 months, most dogs have all their 42 adult teeth and should be finished losing baby teeth.

Little Timeline

• 3–4 months: Front incisors start to loosen and fall out; chewing often increases because gums are sore.

• 4–6 months: Canines (the fangs) and premolars are replaced by adult teeth; this is the peak teething period.

• 5–7 months: Adult molars come in; baby teeth should be gone and chewing usually settles down.

When To Call the Vet

• If your puppy is older than about 7–8 months and still has obvious baby teeth alongside adult teeth, especially canines. This can indicate retained baby teeth that sometimes need removal.

• If you see heavy bleeding, very bad breath, or your puppy seems reluctant to eat, a dental check is a good idea.
