Great Pyrenees puppy feeding chart
A Great Pyrenees grows to about 165 lb (the standard's range is 120–165 lb). Puppy calories track the puppy's current weight, not its adult weight: 25 lb of puppy under four months needs about 1298 kcal a day, and the daily total keeps rising until adult weight, when the factor drops and the dog needs 2850 kcal — fewer calories than it did at 66 lb as a growing puppy (1792 kcal).
Chart: calories and cups as the puppy grows
Weigh the puppy, find the nearest row, feed that amount split into three or four meals under four months and two or three after. Re-weigh every two weeks. Cups use 369 kcal/cup (Purina Pro Plan Complete Essentials Shredded Blend Chicken & Rice (adult dry)); puppy foods are often denser, so use the kcal/cup on your bag — the sizer accepts it.

Where the stages fall for a Great Pyrenees
The 3× factor applies while the puppy is under four months, which for a Great Pyrenees usually means the rows up to roughly a quarter or a third of adult weight — around 25–41 lb. Between four months and maturity the factor is 2×, covering the 66–140 lb rows. Large and giant breeds like this one keep growing well past a year, and large-breed puppy foods are formulated to slow that growth slightly for joint health; the calorie math is the same, the food choice is the vet conversation.
The peak of the chart is the surprise for most owners: at 66 lb and 2× RER the puppy eats 1792 kcal, but the same dog at its full 165 lb as a neutered adult needs only 2850 kcal. Watch for the hand-off and reduce the ration rather than letting the adult food amount "catch up".
Growth to watch in a Great Pyrenees
The standard puts an adult Great Pyrenees at 28–31 in at the withers (26–30 in for females), so a puppy at the 91 lb row — a little over half its adult weight — is typically most of the way to full height and still filling out. The standard gives one weight range for both sexes, so a smaller individual simply stops lower on the chart; switch to the adult factor when growth plateaus on the fortnightly weigh-ins, not at a date. At this adult size the 2× stage lasts longest and the kcal totals run past 3149, so buy puppy food by the large bag and weigh it in grams.
Crate divider positions
The same growth rows are a guide for the divider in the adult-size crate. A Great Pyrenees ends up in a 54 in crate — see the Great Pyrenees crate size page — and the divider should give the puppy only enough room to stand, turn around and lie flat at each stage, moving back roughly every re-weigh.
