Dogs usually teeth (go through the puppy teething phase) for about 3–6 months in total, and most are fully done teething by around 6–7 months of age. Puppies start getting baby teeth at a few weeks old, then begin losing them and getting their adult teeth at around 3–4 months, with the process typically complete by 7–8 months.

Teething timeline

  • Baby (deciduous) teeth start erupting at about 3–4 weeks of age.
  • By 6–8 weeks, most puppies have a full set of 28 sharp baby teeth.
  • Around 3–4 months, baby teeth start falling out and adult teeth begin to come in, which is when chewing and discomfort peak.
  • By 6–7 months, most dogs have all 42 adult teeth and the intense teething phase is usually over.

So, from the start of losing baby teeth to a full adult mouth, dogs “teeth” for roughly 3–4 months, usually between 3 and 7 months of age.

Wondering how long dogs teeth for? Most puppies start losing baby teeth around 3–4 months and finish teething by 6–7 months, when their 42 adult teeth are fully in.
