Is my puppy on track?
See how your pup measures up against real puppies of the same breed, plotted on a growth chart built from 440,000 US puppies.
Check your puppy’s growth
For dogs from 6 weeks to 2 years old. Scroll down for a note on kittens.
Have earlier weights? Add a few from past vet visits and we’ll show whether your pup is holding a steady line. Optional, but it tells you more than one weigh-in.
How to read the chart
The gold line is typical
We start from your breed’s adult weight in the AKC and UKC standards, split by sex, then adjust to what healthy pets really weigh (pet toy breeds run bigger than the standard, giants smaller). Mixed pups use a size class.
The bands show real puppies
Shading shows where healthy puppies actually land: the darkest band holds the middle 50 of every 100, the lightest holds 94. Toy breeds vary more than giants, and young pups more than older ones.
A steady line matters most
One weigh-in shows where your pup sits today. Earlier weigh-ins show whether they’re holding their line. A little drift is normal. We only flag a jump fewer than 1 in 20 healthy puppies make.
Bands come from about 1.7 million weigh-ins of 440,000 US puppies, aged 6 weeks to 21 months, who grew up to a healthy adult weight (data from Salt et al. 2017, PLoS ONE, CC BY 4.0), split by size and sex. Adult weights start from AKC and UKC breed standards, adjusted to the healthy pets in the same records. Checked on 150,000 weigh-ins from puppies the bands never saw: 3.6% fell below the 3rd percentile line and 2.1% above the 97th.
Weighing at home
- Small pups: use a kitchen or baby scale. Set a box or basket on it, zero it, then add the pup.
- Bigger pups: weigh yourself, then weigh yourself holding your pup, and subtract.
- Use the same scale at about the same time of day, before a meal.
- Weigh every 2 weeks until 6 months, then once a month until they’re grown.
What about kittens?
A handy rule: a healthy kitten weighs about 1 pound per month of age until 5 or 6 months (about 2 pounds at 2 months, 4 at 4). Most cats are close to adult size by their first birthday. Big breeds like Maine Coons keep growing for years.
