Medium breed puppy weight chart
This chart shows how puppies of medium breeds, dogs that weigh 20–33 lb (9–15 kg) as adults, typically gain weight from 12 weeks to 2 years. It gives the median and the range where most healthy male and female puppies sit, from our fit of the open Waltham growth data.

Weight chart
The line is the median; the bands hold the middle half and the middle 82% of healthy puppies of the group at each age. Males and females have separate panels.

How big will my puppy get?
Enter your puppy’s sex, age in weeks and weight. You see which band of this chart the weight falls in and where that band sits at 12 and 24 months.
Result
Male, 17 weeks, 12.8 lb
Middle half, above the median
Between the median and the 75th centile.
- Typical range at this age
- 7.6–16.3 lb (3.45–7.42 kg)Median 11.7 lb (5.33 kg)
- If your puppy stays in this band
- At 12 months: 23.0–26.5 lb (10.4–12.0 kg)
- At 2 years: 25.9–29.2 lb (11.7–13.3 kg)
A weight outside the typical range is not a diagnosis. Weigh again on the same scale in a few days, and if it stays there or you are unsure, show the weights to your vet. Body condition matters as much as the number: WSAVA body condition chart for dogs (opens in a new tab).

When do medium breeds stop growing?
The median medium-breed male reaches three quarters of his two-year weight at about 7 months and 90% at about 13 months. Females take a little longer: 8 months and 14 months.
Growth slows a lot in the second year, but the line does not go flat before the chart ends at 2 years. If your dog keeps gaining fast after the first birthday, that is worth a look at body condition with your vet.
A wide group
This group spans dogs of 20–33 lb (9–15 kg) as adults, so the typical range is wide: at 6 months, males in the middle 82% weigh anywhere from 11.4–23.4 lb (5.19–10.6 kg). Two healthy puppies of the same age can sit at opposite edges of the band.
Pugs and Boston Terriers are in this group even though their AKC standards are lighter: the study placed breeds by what they weighed in clinic records. A puppy of such a breed may follow the lower half of the chart, and that alone is no cause for concern.
Breeds in this group
The Waltham study placed the breeds marked “Waltham study” in this size group; we placed the others here from their AKC adult weight. The adult weight is the American Kennel Club’s.
A breed can be in a group whose range does not cover its AKC weight: the study placed breeds by what they weighed in clinic records, which is often more than the breed standard.
Mixed-breed puppies
Choose the chart by the weight you expect your dog to reach as an adult, not by how the puppy looks. This page fits dogs of 20–33 lb (9–15 kg) as adults. The parents’ weights, if you know them, are the best hint; your vet can give an estimate too.
The study did not include mixed breeds. Its authors suggest that the size-group charts may also work for them, but this has not been tested, so treat the bands as a guide.
How to track your puppy’s weight
Weigh on the same scale, at about the same time of day, every week or two while your puppy grows. Veterinarian Caitlin Grant recommends at least every two weeks and ideally every week. Write each weight down with the date and age.
Then compare the line, not one point, with the bands. A puppy that holds its line is growing steadily for its group. If the weight leaves the bands or crosses lines, weigh again in a few days and talk to your vet.
Frequently asked questions
How much should a Beagle puppy weigh at 4 months?
Beagles are in the medium group. At 4 months (17 weeks) the middle 82% of healthy males weigh 7.6–16.3 lb (3.45–7.42 kg) and females 6.6–14.2 lb (2.98–6.42 kg). The AKC describes two Beagle sizes: “under 20 pounds (13 inches & under), 20-30 pounds (13-15 inches)”.
How much should a Pug weigh at 6 months?
At 6 months (26 weeks) medium-breed males weigh 11.4–23.4 lb (5.19–10.6 kg) and females 9.5–19.5 lb (4.31–8.85 kg). The AKC standard for an adult Pug is 14–18 lb (6.4–8.2 kg), lighter than most of the group, so many Pugs track the lower lines.
How big will a medium breed puppy get?
At 2 years the middle 82% of males weighed 18.4–32.5 lb (8.37–14.7 kg) and females 15.6–27.9 lb (7.06–12.7 kg). A puppy that keeps near one centile line often ends near it, and the calculator on this page shows that range for your puppy.
Sources and method
Data: Salt and colleagues, WALTHAM Petcare Science Institute (PLOS ONE, 2017). Their open data hold weighings of healthy purebred dogs from Banfield clinics in the USA, 1994 to 2013. The fit for this group used 12,664 weighings of 4,059 males and 10,024 weighings of 3,350 females.
Method: the article shows its centiles only as figures, so we fitted the open data again the way the article describes (GAMLSS, males and females apart) and checked the result against its figures; the medians agree within 3%. This is our fit of the open Waltham data, not the official WALTHAM chart.
What this chart does not cover
- Puppies younger than 12 weeks and dogs older than 2 years: the data stop there.
- Purebred dogs from clinics in the USA; mixed breeds were not in the study.
- Dogs weighed before neutering; neutering shifted growth only slightly in the study.
- Giant breeds over 88 lb (40 kg) as adults.
- Body condition: a chart compares weight only. Ask your vet or use the WSAVA chart.
