Pug puppies grow toward an adult weight of 14.1–18.1 lb (6.4–8.2 kg) under the American Kennel Club standard, which gives one range for both sexes; the chart below gives the healthy range at each month.
Quick answers
- Adults weigh 14.1–18.1 lb (6.4–8.2 kg); the AKC standard does not separate the sexes for this breed.
- At 6 months a male is usually 10.8–13.9 lb and a female 10.8–13.9 lb — about 77% of adult weight.
- At 12 months a Pug is around 93% of its final weight.
- Fully grown at roughly 12 months.

Weigh on the same scale at the same time of day where you can. The trend across several weighings tells you far more than any single row.
Reading the range
The American Kennel Club gives one weight range for Pugs, 14 to 18 lb, rather than separate figures for males and females, so the two columns above are identical.
In practice the sexes do differ. VetCompass data from England puts the median adult male at 9.9 kg and the median female at 8.2 kg, a gap of about 1.7 kg (3.7 lb) that the standard does not record. A female near the bottom of the chart and a male near the top are both ordinary.
How a small breed grows
Pugs reach roughly 31% of adult weight at 2 months, about 59% at 4 months, and around 93% at 12 months.
A toy breed is already at 36% by 2 months and effectively finished by its first birthday. A Pug that still looks unfinished at 10 months is therefore usually on schedule rather than behind, and is close to full size by its first birthday.

Frequently asked questions
What is the average weight of a Pug?
An adult Pug weighs 14.1–18.1 lb (6.4–8.2 kg), according to the American Kennel Club breed standard, which gives one range for both sexes.
How much should a 3 month old Pug weigh?
A male is typically 6.4–8.4 lb (2.9–3.8 kg) and a female 6.6–8.6 lb (3.0–3.9 kg) — around 46% of adult weight.
How much should a 4 month old Pug weigh?
Roughly 8.2–10.6 lb for a male and 8.4–10.8 lb for a female, about 59% of the way to adult weight.
How much does a 6 month old Pug weigh?
A male is usually 10.8–13.9 lb (4.9–6.3 kg) and a female 10.8–13.9 lb (4.9–6.3 kg).
How much does a 12 month old Pug weigh?
13.0–16.8 lb for males and 13.0–16.8 lb for females — about 93% of final weight, with the rest filling in over the following months.
How big will my Pug get?
At 59% of adult weight by 4 months, a rough shortcut is to double a four-month weight. The calculator on the home page does this properly, using the growth curve for this size class and returning a range rather than one number.
When is a Pug fully grown?
Height is usually settled first; weight keeps filling in until around 12 months. The last 7% of adult weight takes roughly as long as the jump from 3 to 4 months.
Do male and female Pugs weigh different amounts?
The AKC standard gives one range for both, 14 to 18 lb, so the chart columns are the same. Measured Pugs do differ: in VetCompass records the median adult male was 9.9 kg and the median female 8.2 kg. Expect a female to sit lower on the chart than a male of the same age, and do not read that as underweight.
What size class is a Pug?
A small breed, defined by adult weight. That classification determines the growth curve used here: veterinary research shows dogs of similar adult size grow at similar rates regardless of breed.
Is my Pug puppy underweight if it is below the chart?
Not necessarily. The table shows the middle of the healthy range, so plenty of healthy puppies sit below it. A puppy that is consistently below and not gaining, or that has dropped from a higher line to a lower one, is worth a vet visit. A single reading below the range is not.
How can I tell if my Pug is a healthy weight?
Body condition tells you more than the scale. You should be able to feel the ribs under a thin layer of fat without pressing, see a waist from above, and see the belly tuck up from the side. A dog can sit inside the weight range and still carry too much fat.
Why do Pug growth charts disagree with each other?
Most published charts come from one breeder’s litters or from unsourced rules of thumb, and many do not say whether the figures are for males, females or both. The ranges here come from centile curves fitted to millions of veterinary bodyweight records, scaled to the AKC adult range, and split by sex.
Does neutering change how much a Pug weighs?
The research behind these curves found neutering shifted growth trajectory only slightly, by less than the variation between individual dogs, so separate curves were not needed. Neutering is associated with a higher chance of becoming overweight in adulthood, which is a body condition question rather than a growth chart one.
Where these numbers come from
Adult weights are the breed standard figures published by the American Kennel Club. The month-by-month ranges are estimates rather than measurements of this breed: they come from growth centile curves built from around 15 million bodyweight records collected at US primary-care veterinary hospitals, published open-access by Salt and colleagues, and scaled to the adult range above. That research found dogs of similar adult size grow at similar rates regardless of breed, which is what makes the scaling valid. The records were collected between 1994 and 2013 and describe dogs attending veterinary clinics rather than an idealised population. The derived table, the filtering steps and the known gaps are all published, so the arithmetic here can be checked rather than taken on trust.
