How Much to Feed a Great Pyrenees: Feeding Chart by Age and Weight

General nutrition information compiled from product labels and published sources, not veterinary advice. Your veterinarian is the right person to choose a diet for your dog, especially one with a health condition.

If you are asking how much a Great Pyrenees should eat, the honest answer starts with a caution. No single number fits every dog. A Great Pyrenees is a large breed, and the Hill's Pet breed page gives the adult weight as 85 to 120 pounds, with males heavier. That range is wide, and two dogs at the same weight can need very different amounts of food.

This guide shows a way to build a feeding plan. You will read the label guide, check the calories, watch your dog's body shape and adjust in small steps. The chart below uses label data from the brands' own pages. Treat every figure as a starting point. A veterinarian sets the amount for an individual dog.

How we compared the labels

We compared label data published on each brand's own product page: calories per cup, the feeding guide note and the life stage on the label. We did not run feeding trials or taste tests, and we did not feed any of these foods to dogs. Where a brand page did not give a figure, the chart says so rather than guessing.

What you need

A dry measuring cup, or a kitchen scale if your veterinarian prefers weighing food.
The bag, can or pack of the food you actually feed, with the calorie statement and feeding guide.
A current weight for your dog. A vet clinic scale is best, and many clinics let you walk in to weigh a dog.
A notebook or phone note to log weight, portions and treats.
Your veterinarian's contact details, since the final amount is their call.

Step 1: Pick the right life stage of food

Age comes before amount. The Hill's Pet breed page says Great Pyrenees puppies need large-breed nutrition until at least 18 months, and that full adult size can take up to two years. It also notes that calcium and phosphorus ratios matter for bone development.

Dog Food Advisor explains that growth and all-life-stages foods must state whether they include or exclude growth of large-size dogs, which means dogs of 70 pounds or more as adults. A Great Pyrenees falls in that class. For a puppy, look for the wording "including growth of large-size dogs" on the label. If the statement is missing or unclear, ask the brand or your veterinarian.

PetMD says the breed generally does well on food formulated for large breeds, and advises discussing diet with a vet.

Step 2: Read the calories, not just the cups

Cups are a poor way to compare foods. One cup of a dense kibble can hold more than twice the calories of a cup of a fresh food. The chart shows how far apart they are.

Always use the feeding guide on the food you buy. Do not carry a cup amount from one food to another.

Great Pyrenees feeding chart by life stage and weight

The sources do not give one cup amount that suits every Great Pyrenees at every age, and we will not invent one. The chart instead lines up each life stage with the label data we could confirm. Check the brand page for the full feeding table or calculator.

A few notes on reading this chart. Royal Canin's Giant Puppy page covers puppies only up to 8 months, so a Great Pyrenees would need a different life stage after that. The VICTOR rule for adults over 100 pounds comes from that brand's own page and applies only to that food. Nom Nom Beef Mash lists a lower per-cup calorie figure than the dry foods, so a cup of it is a much smaller share of the day's energy.

Several brand pages did not give a full verbatim AAFCO sentence or a kibble size in what we could confirm. If those details matter to you, check with the brand.

Step 3: Start with the label amount for your dog's target weight

Find your dog's expected adult weight or current weight on the brand's feeding table or calculator. Pick the amount for that weight. Write it down as the daily total, then divide it into meals.

For a puppy, the label guide usually moves with age and expected adult weight. Re-check it as your puppy grows, since a table that fit at four months will not fit at ten.

If the page offers only a calculator, use it and note the result. If your dog is on a fresh food, the brand's calculator works from calories, so keep that calorie figure handy.

Step 4: Split the day's food into meals

PetMD lists bloat, also called GDV, as a life-threatening risk in the breed. Its advice includes feeding multiple small meals, avoiding vigorous exercise around mealtimes and avoiding raised bowls. PetMD also notes that a gastropexy is often done as a precaution against GDV.

That does not mean any feeding schedule rules bloat out. It means a split-meal routine and calm time after eating are sensible habits. Ask your veterinarian about bloat risk and whether a gastropexy makes sense for your dog.

Freshpet's page says its food can be fed as one meal daily or divided into two. Dividing is the choice that fits PetMD's advice.

Step 5: Score your dog's body condition

The scale tells you the weight. Your hands and eyes tell you whether that weight is right. Body condition scoring is a simple check that many veterinary clinics use, usually on a 5-point or 9-point scale. Ask your vet to show you how at the next visit.

The Great Pyrenees has a thick double coat, which can hide the body underneath. Use your hands, not just your eyes.

Ribs. Run your palms along the sides of the chest. In an ideal condition you can feel the ribs under a thin layer of fat without pressing hard. If you must dig to find them, the dog may be carrying extra weight. If they stick out sharply, the dog may be too thin.
Waist from above. Stand over your dog. You should see a gentle taper behind the ribs. A straight or bulging outline can mean extra weight.
Tuck from the side. The belly should rise slightly from the chest toward the hind legs. A belly that hangs level or low can point to extra weight.
Spine and hips. You should feel them with light pressure, but they should not be sharply visible.

Check every two to four weeks and write down what you find. For a growing puppy, the Hill's Pet breed page says controlled growth supports joints, so a lean, steady puppy is the aim rather than a fast-growing one. The page also says hip and elbow dysplasia can occur in large-breed dogs. PetMD adds that these conditions are hereditary, and that exercise, weight and nutrition can influence them. Food does not cure or prevent them. Your vet can say what a healthy growth curve looks like for your puppy.

Step 6: Adjust for activity, age and treats

Label guides assume an average dog. Royal Canin's Large Adult page, for example, lists daily amounts by target weight and by activity level. That shows even the brand expects the amount to move with the dog's life.

Think about these factors:

Activity. A dog that patrols a property or hikes most days may need more than a dog that mostly rests indoors. Do not assume. Let the scale and body condition show it.
Life stage. A mature dog may need fewer calories. Hill's makes a separate large breed formula for dogs aged 6 and over, with 352 kcal per cup on its label.
Treats and chews. They carry calories too. Many vets suggest keeping them a small share of the day's food. Ask yours for a figure for your dog.
Season and health. Appetite can shift with heat, illness or medication. Tell your vet about big changes.

Change the amount in small steps, then wait two to four weeks before judging the result. Large changes in a day or two upset digestion and make it hard to tell what worked.

Step 7: Weigh, log and review with your veterinarian

Weigh your dog on a regular schedule and log it with the daily amount. Puppies change fast, so more frequent checks help. For adults, a check at each vet visit is a reasonable minimum.

Bring the log, the food label and the treat list to the appointment. Your veterinarian can set the amount for your individual dog, and can tell you if a medical issue is involved. The Hill's Pet breed page notes that some lines are predisposed to Addison's disease and that osteosarcoma is more frequent in giant breeds, with regular exams advised. Diet questions belong in those same conversations.

A prescription diet is something only a veterinarian prescribes. Do not choose one on your own.

Tips

Measure every meal. Scooping with a coffee mug or by eye drifts over time.
Keep one source of truth. Use the label of the exact food in the bowl.
Switch foods slowly, and ask your vet how to do it for your dog.
Keep the dog's eating area calm, and give a rest period after meals.
Re-weigh when anything changes: a new food, a new routine or a new season.

Common mistakes to avoid

Using cups from the wrong food. The chart shows calories per cup running from 201 to 427 across these labels. Cup amounts do not transfer.
Feeding adult food to a puppy. The Hill's Pet breed page points to large-breed puppy nutrition until at least 18 months.
Ignoring the coat. A fluffy coat hides weight gain. Use your hands.
Counting only meals. Treats, chews and table scraps add up.
Making big jumps. Change the portion a little at a time and watch for weeks.
Treating the label as a prescription. It is a starting point written for average dogs.
Choosing food by marketing. Read the AAFCO statement, the life stage and the calories rather than the front of the bag.

A note on the FDA and heart health

You may have read about diet and canine dilated cardiomyopathy (DCM). The FDA Center for Veterinary Medicine says its latest update on the topic is dated December 23, 2022, and that it does not plan further public updates until there is meaningful new scientific information. The agency's page is the place to read the details. If you are choosing between formulas, ask your veterinarian about it. Every food in the chart above is listed as not grain-free except JustFoodForDogs Beef & Russet Potato, which the brand lists as grain-free. Freshpet and Nom Nom make no grain-free claim on the pages we read.

What to expect

If the amount suits your dog, you may notice steady energy, a body condition that stays in range and a puppy that grows at a controlled pace. Stools may be consistent from day to day. These signs are a rough guide and not a promise. Results vary with genetics, activity, health and the food.

If your dog gains or loses weight, seems hungry all the time, has loose stools or loses interest in food, call your veterinarian. Those signs are worth a professional look rather than another guess at the cup.

The label gives you a starting point. Your dog's body, the scale and your veterinarian turn it into the right amount for them.
