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.
