If you’ve just brought home a Pug puppy, the calculator below estimates its adult size from its current weight — personalized to your dog, not just a breed average.
Estimates combine your puppy’s current trajectory with typical growth curves for this breed and size class. Individual dogs vary — nutrition, genetics and neuter timing all matter. For health concerns, ask your vet.
The Pug is a small breed. Adult males typically weigh 14–18 lb (6.4–8.2 kg) and females 14–18 lb (6.4–8.2 kg). Most Pugs reach about half their adult weight around 3.8 months, hit 90% by roughly 7.9 months, and are fully grown near 11 months. Small breeds do the bulk of their growing in the first six months, then fill out slowly.
When do Pugs stop growing?
Most Pugs reach their full adult height and weight by about 11 months. Growth is fastest before 3.8 months, then slows steadily — by 7.9 months your puppy will be about 90% of its final size.
How much should a Pug puppy weigh at 4 months?
A typical 4-month-old Pug weighs roughly 7–10 lb, about 53% of its adult weight. Use the calculator above with your puppy’s exact weight for a personalized estimate — individual dogs vary.
