Puppy growth chart: weight by month

Pick your puppy's breed or enter the adult weight you expect. You get a month-by-month growth chart with the typical weight and the normal range, and you can add today's weight to see where your puppy sits.

Growth curves come from healthy purebred dogs at US veterinary hospitals. They describe typical growth, not a target. If your puppy loses weight, stops gaining, or looks thin or round, talk to your vet.

How to read a puppy growth chart

The orange line is the median: the weight that half of healthy puppies heading for the same adult weight were under at each age, and half over. The darker band holds the middle half of puppies (25th to 75th centile) and the pale band eight in ten (10th to 90th). A puppy anywhere in those bands is normal.

The curves come from our analysis of the open data behind a 2017 PLOS ONE growth-standard study by Salt and colleagues: 318,751 weigh-ins from 92,907 healthy purebred dogs, each compared with its own weight at 2 to 3 years. Because the chart is scaled to one adult weight, it is only as good as that number. For a purebred, the breed standard midpoint is a fair start; for a mixed breed, the parents' weights or our puppy weight calculator give a better one.

The most useful habit is watching the shape, not one number. WALTHAM, whose growth charts come from the same research, says a puppy that follows a centile line, or the space between two lines, is growing healthily, and that the important thing is not to cross two lines.

How fast do puppies grow?

Growth is fastest in the first few months and then tails off. For a puppy heading for 50 lb (23 kg), the median curve gains about this much per week:

2 to 3 months: about 1.4 lb (0.6 kg) a week
3 to 4 months: about 1.6 lb (0.7 kg) a week
4 to 6 months: about 1.3 lb (0.6 kg) a week
6 to 9 months: about 0.7 lb (0.3 kg) a week
9 to 12 months: about 0.2 lb (0.1 kg) a week

Smaller dogs gain less per week in pounds but start their slowdown earlier; big dogs keep a steep curve for longer. That is why weighing helps most in the first six months. WALTHAM suggests weighing every 2 to 4 weeks up to 6 months of age, then every 1 to 3 months until your dog is fully grown. Our puppy weight tracker plots each weigh-in on these curves for you.

Large and giant breed puppies: slow and lean

Big puppies are where growth charts matter most. VCA explains that a large or giant puppy that is overfed may not look fat, but it will grow faster than its skeleton can keep up with, which raises the risk of developmental orthopedic disease. Its advice is to keep growing puppies at a body condition score of 4 out of 9, slightly on the lean side. In other words, feed for a lean puppy, not for the top of the chart.

AAHA's nutrition guidelines say to feed a diet made for growth until skeletal maturity, which for some large and giant breeds is not until about 15 to 16 months, and to avoid excess calcium. Look for a food labelled as complete and balanced for growth of large-size dogs (70 lb or more as an adult). The giant curve on this page is a rough guide: the original study could not build a reliable standard for dogs over 88 lb (40 kg) because breeds such as the Great Dane, Mastiff and Rottweiler grew so differently. You can check your puppy's shape at home with our body condition score checker.

Frequently asked questions

How big will my puppy be at 6 months?

At 6 months a typical puppy weighs about 71% of its adult weight if it is a toy breed and about 68% if it is Labrador-size, according to the growth records behind this chart. Giant breeds are further behind, at about 62%.

Are puppy growth charts different for males and females?

Males of most breeds end up heavier, which is why WALTHAM publishes separate charts by sex and breed standards list separate weight ranges. Here, choosing the sex changes the adult weight the chart is built on; the shape of the curve relative to adult weight is shared.

My puppy doesn't match the chart. Is something wrong?

Probably not. The chart line is the median, so half of healthy puppies are lighter and half heavier. What matters is that your puppy follows its own line steadily. A puppy that drops or climbs across two bands, or stops gaining, should be seen by a vet.

Should I feed my puppy more so it grows bigger?

No. VCA warns that overfed large and giant breed puppies may not look overweight but grow faster than their skeleton can cope with, which raises the risk of developmental bone and joint disease. Vets aim to keep growing puppies lean rather than push them up the chart.

When should I switch from puppy food to adult food?

AAHA's nutrition guidelines say to feed a growth diet until skeletal maturity: about 1 year for small and medium dogs, and closer to 15 to 16 months for some large and giant breeds. VCA suggests about 18 months for large breeds and 24 months for giants. Ask your vet for your puppy's breed.
