Great Pyrenees Weight Chart by Age

An adult male Great Pyrenees weighs about 100 lb (45.4 kg) and an adult female about 85 lb (38.6 kg), according to the American Kennel Club breed standard.

A male is typically about 32 lb (14.5 kg) and a female about 29 lb (13.0 kg) — around 32% of adult weight.

Roughly about 45 lb for a male and about 40 lb for a female, about 45% of the way to adult weight.

A male is usually about 67 lb (30.6 kg) and a female about 58 lb (26.3 kg).

about 92 lb for males and about 78 lb for females — about 92% of final weight, with the rest filling in over the following months.

At 45% 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.

Height is usually settled first; weight keeps filling in until around 24 months. The last 8% of adult weight takes roughly as long as the jump from 3 to 4 months.

Yes, and by enough to matter. Adult males run about 100 lb (45.4 kg) against about 85 lb (38.6 kg) for females. Comparing a female against a chart that does not separate the sexes will usually make her look underweight when she is not.

A giant 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. 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.

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 Great Pyrenees weighs 45.4 kg for males and 38.6 kg for females under the American Kennel Club standard. On the median growth curve a male is 14.5 kg at 3 months, 30.6 kg at 6 months and 41.8 kg at 12 months; a female 13.0 kg, 26.3 kg and 35.3 kg. Every row of the chart above gives kilograms under the pounds.

The American Kennel Club standard gives females about 85 lb (38.6 kg). On the female growth curve a female Great Pyrenees is about 40 lb at 4 months, 58 lb at 6 months and 78 lb at 12 months, reaching adult weight at around 24 months. The Female column of the chart above gives every month.

The American Kennel Club standard gives males about 100 lb (45.4 kg). On the male growth curve a male Great Pyrenees is about 45 lb at 4 months, 67 lb at 6 months and 92 lb at 12 months, reaching adult weight at around 24 months. The Male column of the chart above gives every month.
