Puppy Weight Chart by Age
How big will my puppy get? This one-page chart shows the share of adult weight a puppy has usually reached at 2, 3, 4, 6, 9 and 12 months, for toy, small, medium, large and giant breeds, and the age each size is usually full-grown. Divide your puppy’s current weight by the percentage for its age and size to get an estimated adult weight; the growth log below keeps the real numbers. It uses the same growth model as the site’s free Puppy Weight Calculator (AAHA life-stage and WSAVA nutrition guidance plus published growth curves).

- Pick your puppy’s size group from the caption under the chart (ask your vet or breeder if you are unsure).
- Weigh your puppy on the same scale every 2–4 weeks and write it in the log with its age.
- Divide the weight by the percentage for that age and size to estimate adult weight.
- Watch the trend over several weigh-ins rather than any single number, and bring the sheet to vet visits.

- How accurate is a puppy weight chart?
- Treat it as a ballpark. For a purebred of a known size, growth-curve estimates usually land within about 10–20%, and they get more accurate as the puppy gets older. Mixed breeds vary more, and estimates before 8–12 weeks are loose.
- When do puppies stop growing?
- It depends on size: toy breeds are usually close to adult weight by about 12 months, small breeds by about 14, medium by about 16, large by about 20 and giant breeds by about 24 months.
- Which size group is my mixed-breed puppy?
- Use your best guess from the parents or the breeds in the mix, and update it as the puppy grows. Your vet can also help, since they see how your puppy is filling out at each visit.
- What if my puppy stops gaining weight?
- A sudden stall, weight loss, or a puppy who looks too thin or too round for its age is worth a vet visit. Steady, gradual gain along the curve is what you want to see.
