Saint Bernard Feeding Guide
How much to feed your Saint Bernard — daily calories, portion sizes, and feeding schedule
Originating in Switzerland, the Saint Bernard is a giant-sized working breed that currently holds the #43 spot in AKC registrations. Has an uncanny ability to sense impending avalanches and storms, a trait that made them invaluable to the monks who depended on them for rescue work. Bred for physically demanding tasks like guarding, hauling, and rescue, the Saint Bernard is a powerful giant breed from the Working Group. Fueling their muscular frame requires attention to protein quality, calorie density, and joint-supporting nutrients. An adult Saint Bernard needs between 1894 and 2567 calories per day, though this varies with age, weight, activity level, and individual metabolism.
Feed an adult Saint Bernard approximately 1.8–3.6 cups of quality kibble daily, split into two meals. Males (120–180 lbs) may need slightly more than females (102–158 lbs). Males weigh 140-180 pounds, females 120-140 pounds; some exceed 200 pounds, though the breed standard favors proportional, powerful builds over sheer bulk.. With moderate energy (2/5), portions at the middle of guidelines usually suffice.

Feeding Strategy for Saint Bernards
With a calm, low-energy temperament, the Saint Bernard is particularly susceptible to overfeeding. Their daily requirement of 5-6.8 cups may seem surprisingly small, but exceeding it regularly leads to weight gain. A weight-management or light formula can help, and measuring every meal with a proper cup — not estimating — is essential for this breed.

Exercise & Feeding for Saint Bernards
The Saint Bernard has modest exercise needs — 20-30 minutes of gentle walks and indoor play daily is usually sufficient. Because of their low activity level, there is rarely a need to adjust food intake for exercise. The bigger risk is overfeeding a relatively sedentary dog. If your Saint Bernard gets less activity than usual (bad weather, recovery from illness), consider reducing portions by 10%.
Joint Health & Nutrition
Joint health is a primary nutritional concern for Saint Bernards, which are predisposed to Hip Dysplasia and Elbow Dysplasia. Diet plays a preventive and management role at every life stage. For puppies, controlled growth rate and proper calcium-phosphorus ratios protect developing joints. For adults, maintaining ideal body weight reduces mechanical stress on joints. Specific nutrients can slow cartilage degradation and reduce inflammation.
Recommended Joint Supplements
Heart-Supportive Nutrition
Saint Bernards have a genetic predisposition to Dilated Cardiomyopathy, making heart-supportive nutrition especially important. Choose foods naturally rich in taurine (found in animal proteins, especially dark meat and organ meats) and L-carnitine. Keep sodium moderate — not salt-free, but avoid high-sodium treats and table scraps. The FDA has investigated potential links between grain-free diets and dilated cardiomyopathy (DCM); while research is ongoing, discussing diet choices with your veterinarian is prudent for this breed. Omega-3 fatty acids from fish oil have demonstrated cardiovascular benefits in dogs, supporting healthy heart rhythm and reducing inflammation.
Coat & Skin Nutrition
The Saint Bernard's Double requires nutritional support from the inside out. Double-coated breeds undergo significant seasonal shedding (known as "blowing coat") in spring and fall, during which nutritional demands for skin and hair production increase. A diet deficient in essential fatty acids, biotin, or zinc will show in the coat quality within weeks — look for dullness, excessive shedding, or dry, flaky skin as early warning signs.

Common Feeding Mistakes to Avoid
Overfeeding because the Saint Bernard always seems hungry
Some breeds appear perpetually hungry due to genetics or behavior. Stick to measured portions and use low-calorie treats like baby carrots, green beans, or ice cubes. If your Saint Bernard inhales food, try a slow-feeder bowl.
Using a puppy formula designed for small breeds
Large and giant breed puppies need controlled calcium and phosphorus levels to prevent developmental orthopedic diseases. Always choose a large-breed puppy formula that supports slow, steady growth rather than rapid weight gain.
Skipping joint supplements until problems appear
For breeds predisposed to joint issues, preventive supplementation with glucosamine and omega-3 fatty acids can help protect cartilage before damage occurs. Starting these supplements early — even at 1-2 years old — is more effective than waiting for symptoms.
Letting the puppy grow as fast as possible
Giant breed puppies that grow too quickly are at higher risk for developmental bone and joint disorders. Feed a giant-breed puppy formula and aim for slow, steady growth — reaching full adult size at 18-24 months is healthier than hitting target weight at 12 months.
Switching foods abruptly without a transition period
Any diet change — brand, flavor, or formula — should happen gradually over 7-10 days. Mix increasing amounts of the new food with decreasing amounts of the old. Abrupt switches cause digestive upset (diarrhea, vomiting, gas) in most dogs, Saint Bernards included.

Breed-Specific Nutritional Needs
Based on health conditions common in Saint Bernards, consider these nutritional adjustments:
Glucosamine & Chondroitin
Add a joint supplement with glucosamine (500-1000mg) and chondroitin. Consider foods with added omega-3 fatty acids (EPA/DHA) to reduce inflammation.
Saint Bernard Ideal Weight
To determine if your Saint Bernard is at a healthy weight (120–180 lbs target): Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them. Waist check: Viewed from above, there should be a visible waist behind the ribs. Tuck-up: From the side, the abdomen should tuck up behind the rib cage. Their double coat can mask weight gain, so hands-on assessment is essential.
Male Saint Bernard
120-180 lbs
54-82 kg
Female Saint Bernard
102-158 lbs
46-72 kg
