Puppy growth chart

Add your puppy’s weigh-ins to see them against the expected growth band for their breed or size.

Growth check

Pick a breed or add a weigh-in to see the chart.

Not veterinary advice. PupRange gives estimates from published veterinary sources. Every dog is different. If you’re worried, call your veterinarian.

When to call your vet

  • Body condition is 3 or lower, or 7 or higher, on the 9-point chart.
  • Weight drops, or stays the same across two weigh-ins while your puppy should still be growing.
  • Your puppy seems unwell: not eating, vomiting, diarrhea or low energy.

On our growth curves a typical toy puppy reaches half its adult weight at about 11.5 weeks and a typical large-breed puppy at about 16 weeks, so the same age can mean a very different stage of growth.

How it’s calculated

The band shows where puppies of the same breed or size usually are at each age, from early to late maturing. It uses the same growth curves as our puppy weight and size calculator.

Want a breed’s own chart, with weight by month already filled in?

  1. Adult range. With a breed, we start from its adult weight range in the American Kennel Club’s breed weight chart. Without one, enter an expected adult range, or carry it over from the puppy weight calculator.
  2. Band. The low edge is the bottom of the adult range times the share of adult weight a late-maturing puppy has at that age. The high edge is the top of the range times the share for an early-maturing puppy. The middle line uses the typical curve.
  3. Your weigh-ins. Each point is marked inside, below or above the band. Two weigh-ins in a row outside the band are worth mentioning to your vet.
  4. Drift. For two weigh-ins at least 2 weeks apart, we project an adult weight from each. If the projections differ by 15% or more, we suggest a vet check. WALTHAM’s growth chart guidance is to talk to your vet when a puppy crosses two centile lines. We don’t have centile tables, so the 15% threshold is our own stand-in for that rule, not a published cut-off.

WALTHAM suggests weighing every 2–4 weeks until 6 months, then every 1–3 months. The middle line is not a target: healthy puppies sit anywhere in the band. Every step, source and open question is on our methodology page.

Questions owners ask

Is the middle line a target weight?

No. WALTHAM’s growth chart guidance says the middle line is not a target for every puppy. Healthy puppies sit anywhere in the band. What matters more is that your puppy keeps roughly the same position from one weigh-in to the next.

When should a weigh-in worry me?

WALTHAM suggests talking to your vet if a puppy crosses two centile lines on its chart. PupRange flags a change of 15% or more in the projected adult weight between two weigh-ins. That threshold is our own proxy for line crossing, not a published cut-off.

How often should I weigh my puppy?

WALTHAM’s puppy growth chart guidance is every 2 to 4 weeks until 6 months, then every 1 to 3 months.

When do dogs stop growing?

VCA Animal Hospitals and the Canadian Academy of Veterinary Nutrition say small and medium breeds are mature by about 10 to 12 months, and large and giant breeds by about 18 to 24 months. Giant breeds can keep filling out until about 2 years.
