Saint Bernard Feeding Guide

How much to feed your Saint Bernard — daily calories, portion sizes, and feeding schedule

Energy: 2/5

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.

Saint Bernard Feeding Schedule

1

Morning (7-8 AM)

2.5-3.4 cups kibble

2

Evening (5-6 PM)

2.5-3.4 cups kibble

Split Meals

Feeding your Saint Bernard two meals per day (instead of one large meal) helps prevent bloat, maintains steady energy, and improves digestion.

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

+Glucosamine HCl (500-1000mg/day) — supports cartilage repair and joint fluid production
+Chondroitin sulfate (400-800mg/day) — protects existing cartilage from enzymatic breakdown
+EPA/DHA omega-3 fatty acids from fish oil — clinically proven to reduce joint inflammation
+Green-lipped mussel extract — contains a unique omega-3 (ETA) with strong anti-inflammatory properties
+MSM (methylsulfonylmethane) — provides sulfur for connective tissue and may reduce pain

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.

Key Nutrients for Coat Health

+Omega-6 fatty acids (linoleic acid) — the primary building block of healthy skin and coat
+Omega-3 fatty acids (EPA/DHA from fish oil) — reduce inflammatory skin conditions and add shine
+Biotin (Vitamin B7) — supports keratin production, the structural protein of hair
+Zinc — essential for skin cell turnover; deficiency causes crusting, hair loss, and dull coat
+Vitamin E — antioxidant that protects skin cells and may reduce excessive shedding

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.

Saint Bernard-Specific Feeding Tips

Tip 1

Use an elevated food bowl set at chest height for your Saint Bernard. This promotes better posture during meals and may reduce the amount of air swallowed, which is especially important for deep-chested breeds.

Tip 2

Swap high-calorie treats for raw vegetables. Most Saint Bernards enjoy baby carrots, cucumber slices, green beans, and blueberries — all under 5 calories per piece compared to 20-40 calories for commercial treats.

Tip 3

During seasonal coat changes (spring and fall), your Saint Bernard's nutritional needs may shift slightly. Omega-3 and omega-6 fatty acids support healthy coat renewal. Consider adding a fish oil supplement during heavy shedding periods.

Tip 4

Giant breed puppies should stay on puppy food until 18-24 months — longer than other sizes. Their bones and joints are still developing well past their first birthday. Switching to adult food too early can deprive them of the specific nutrient ratios they need for healthy skeletal growth.

Tip 5

For Saint Bernards with cardiac predispositions, choose foods that contain adequate taurine and L-carnitine, or supplement these amino acids. Recent research links grain-free diets to heart issues in some breeds — discuss diet choices with your veterinarian.

Tip 6

The Saint Bernard's shorter lifespan of 8-10 years means they enter their senior stage earlier. Consider transitioning to a senior formula by age 5-6 to proactively support aging joints and organs.

Breed-Specific Nutritional Needs

Based on health conditions common in Saint Bernards, consider these nutritional adjustments:

Hip Dysplasia

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.
