Great Pyrenees portions by weight
| Adult weight | RER | Daily target | Kibble / day | Cups / day | Per meal (×2) | Raw / day |
|---|---|---|---|---|---|---|
| 45.0 kg | 1,216 kcal | 1,946 kcal | 473 g | 4.7 | 237 g | 900 g |
| 59.0 kg | 1,490 kcal | 2,384 kcal | 580 g | 5.8 | 290 g | 1,180 g |
| 73.0 kg | 1,748 kcal | 2,797 kcal | 680 g | 6.8 | 340 g | 1,460 g |
Neutered adult (×1.6), kibble at 370 kcal/100 g, 10% treat allowance removed. Raw at 2.0% of body weight (size-correct rate). Cups ≈ grams ÷ 100 (typical kibble — weigh in grams for accuracy).
Worked example: a 59.0 kg Great Pyrenees
A 59.0 kg adult Great Pyrenees (neutered): RER 1,490 × 1.6 = 2,384 kcal − 238 kcal treats ÷ 3.7 kcal/g = 580 g — that is 290 g per meal, twice a day. The same arithmetic runs in the calculator above: change the weight or the life stage and every number follows.
Great Pyrenees puppy feeding by age
| Age | Factor | Meals / day | Note |
|---|---|---|---|
| Under 4 months | ×3.0 | 3–4 | On current weight — weigh every 2 weeks |
| 4–8 months | ×3.0 → ×2.0 (taper) | 3–4 | Factor falls smoothly — weigh every 2 weeks |
| 8–12 months | ×2.0 | 3 | 3 meals; 2–3 from 6 months |
| 12 months to adult | ×1.6–1.8 | 2 | Adult factor from 18–24 months |
Factors multiply RER on the puppy's current weight, not adult weight. Large and giant breeds keep the growth factors until 18–24 months.
Feeding notes for the Great Pyrenees
For a sedentary giant, the inactive factor is not a diet — it is maintenance. Giants hide fat under heavy coats and loose skin; judge condition by ribs and waist, never by appetite or the empty bowl.
What makes feeding a Great Pyrenees different: Great Pyrenees are giants with a low metabolism for their size and a bloat risk: split meals, rest after eating, and keep them lean — the thick coat hides weight, so the scale is the only honest check.
Health, treats and the senior years: Great Pyrenees are prone to bloat at every age, so the two-meal rule never retires — a deep-chested senior should never eat one large meal. In old age, keep the dog lean and the factor honest: a Pyrenees that looks thin is usually just a Pyrenees under a thick coat.
Training, treats and everyday feeding: Great Pyrenees do best on two or three smaller meals a day rather than one large one — a deep-chested giant should never eat a big meal and then exercise. They eat surprisingly little for their size, so judge by the ribs and the scale every two weeks, not by the size of the dog.
Weight & condition for the Great Pyrenees: Great Pyrenees are giants with a low metabolism for their size and a bloat risk: split meals, rest after eating, and keep them lean — the thick coat hides weight, so the scale is the only honest check. They eat surprisingly little for their size, and feeding the table for a smaller giant is usually the right instinct.
Body condition check: A number on the scale is not a body condition. Score the dog on the 9-point scale and aim for 4–5 — ribs palpable through a thin fat layer, waist visible from above, abdomen tucked when viewed from the side. Can't feel the ribs? Feed 10% under the table. Ribs plainly visible? Feed 10% over it.
Puppies of this size class reach adult factors at about 18–24 months; until then, growth portions follow the puppy factors (×3.0 under 4 months, tapering to ×2.0 by 8 months) on current weight, recalculated every two weeks. Individual dogs vary by up to ±50% from any formula — the scale and your hands on the ribs outrank this table.

Great Pyrenees feeding questions
How much food should a Great Pyrenees eat per day?
Across the full adult weight range (45–73 kg), a Great Pyrenees needs about 1,946–2,797 kcal/day — 473–680 g of typical kibble (370 kcal/100 g) after the 10% treat allowance is removed — depending on weight, sex and activity. A typical adult at the middle of the range (59.0 kg) needs about 2,384 kcal/day, roughly 580 g, split over 2 meals.
How many meals a day should a Great Pyrenees eat?
Two or three smaller meals a day is right for a Great Pyrenees — split the daily 580 g (2,384 kcal) for a 59.0 kg adult across them, never served as one big bowl. A deep-chested giant should never eat a large meal and then exercise, and the one-hour rest after eating is the standard precaution. A pyr that eats surprisingly little for its size is not being underfed — judge by the ribs and the scale every two weeks, not by the size of the dog.
How many cups of food does a Great Pyrenees need per day?
About 580 g/day is roughly 5.8 cups at the typical density of 100 g per cup — but cups vary by up to 40% between kibbles, so weigh the grams once and the question disappears. A cup is a volume; grams are the portion. At 580 g a day, a 10% scooping error is about 58 g — a small dog's entire meal — so weighing matters more, not less, as portions grow.
How do I switch a Great Pyrenees to a new food?
Over 10–14 days for a giant breed: 25% new food for 3 days, 50% for 3–4 days, 75% for 3–4 days, then 100% — keeping the total daily grams at the number on this page throughout. Giant breeds do best with gradual changes and smaller, more frequent meals; if stools loosen, hold at the current mix for an extra two days before moving on.
How much should a Great Pyrenees puppy eat?
Giant puppies are the longest, most delicate growth project: adult factors only at 18–24 months. Use ×3.0 under 4 months, tapering to ×2.0 by 8 months, on current weight, keep them visibly lean, and never 'feed for size' — genetics sets the size, calories only set the fat.
How much raw food does a Great Pyrenees need?
At the size-correct BARF rate of 2.0% of ideal body weight, a 59.0 kg Great Pyrenees eats about 1,180 g of raw food per day — split 70% muscle meat, 10% raw edible bone, 5% liver, 5% other organ, 10% vegetables and fruit on the BARF model.
How does feeding a Great Pyrenees change as they age?
From about 18–24 months a Great Pyrenees counts as fully adult; the senior shift usually arrives years later, when activity and muscle mass fall. The calculator's senior factor (×1.4 instead of ×1.6) trims a 59.0 kg Great Pyrenees from 2,384 to about 2,086 kcal/day — roughly 507 g of typical kibble. Make the change gradually and judge by body condition, not birthdays alone: a still-active older Great Pyrenees may hold condition on the adult number.
Do Great Pyrenees eat as much as other giant breeds?
No — they have a low metabolism for their size and hold condition on surprisingly little food. A 59.0 kg adult needs about 2,384 kcal/day (580 g of kibble) on the standard factor, and many Pyrenees hold condition on less. Judge by the ribs and the scale every two weeks, not by the size of the dog: a giant that looks hungry is usually just a Pyrenees.
How should I feed my Great Pyrenees to lower bloat risk?
Split the day's 580 g into two or three smaller meals, rest the dog for about an hour after eating, and avoid hard exercise on a full stomach. The portion itself doesn't change — a 59.0 kg adult still needs about 2,384 kcal/day — but how it is served matters for a deep-chested giant. If a Pyrenees ever retches without producing anything and the belly looks swollen, treat it as an emergency.
