Chow Chow Weight Chart by Age

An adult Chow Chow weighs 45.0–70.0 lb (20.4–31.8 kg), according to the American Kennel Club breed standard, which gives one range for both sexes.

At 3 months a typical male weighs 17.7 lb (8.0 kg) and a typical female 18.6 lb (8.4 kg). Half of males weigh 14.7–20.9 lb (6.7–9.5 kg), and half of females 15.4–21.8 lb (7.0–9.9 kg). A typical puppy is around 31% of its adult weight at this age.

At 4 months a typical male weighs 26.3 lb (11.9 kg) and a typical female 27.1 lb (12.3 kg). Half of males weigh 22.3–30.2 lb (10.1–13.7 kg), and half of females 23.1–31.1 lb (10.5–14.1 kg). A typical puppy is about 46% of the way to adult weight.

At 6 months a typical male weighs 40.3 lb (18.3 kg) and a typical female 40.5 lb (18.4 kg). Half of males weigh 34.8–45.8 lb (15.8–20.8 kg), and half of females 35.3–46.0 lb (16.0–20.8 kg).

At 12 months a typical male weighs 53.6 lb (24.3 kg) and a typical female 53.5 lb (24.3 kg). Half of males weigh 46.9–60.6 lb (21.3–27.5 kg), and half of females 46.9–60.1 lb (21.3–27.2 kg). That is about 93% of final weight, with the rest filling in over the following months.

Dogs of this size that were weighed both as puppies and as adults ended up at about 2.3 times their 4-month weight, in records from US veterinary clinics. The calculator on the home page uses those records for the puppy’s own age and weight, and returns a range rather than one number.

Height is usually settled first; weight keeps filling in for longer. On the growth curve for its size, a Chow Chow stays above 95% of adult weight from about 13 months, and the last 7% after its first birthday comes on slowly.

The American Kennel Club gives one range for both sexes, 45 to 70 lb, so the male and female charts above share one adult range. The breed standard sets height, 17 to 20 inches, rather than weight, so frame size rather than sex decides where a grown Chow sits in that range. Judge it by body condition, felt by hand under the coat.

A large 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.

Not necessarily: 1 in 10 healthy puppies weighs less than the lightest figure in the table. What matters more is the trend. A puppy that drifts from one part of the range to a lower one is worth checking: look at its body condition and ask your vet about its diet. A single low reading is not a diagnosis.

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.

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.

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.

An adult Chow Chow weighs 20.4–31.8 kg for both sexes under the American Kennel Club standard. A typical male weighs 8.0 kg at 3 months, 18.3 kg at 6 months and 24.3 kg at 12 months; a typical female 8.4 kg, 18.4 kg and 24.3 kg. The charts above give every month in kilograms, with a switch to pounds.

The American Kennel Club standard gives one range for both sexes, 45.0–70.0 lb (20.4–31.8 kg); it does not publish a separate female figure. A typical female Chow Chow weighs 27.1 lb at 4 months, 40.5 lb at 6 months and 53.5 lb at 12 months. Weight stays above 95% of the adult figure from about 13 months. The female chart above gives every month.
