Nutrition is a cornerstone of Saint Bernard health. An adult Saint Bernard weighing 54–82kg typically requires 2050–2550 kcal of high-quality food per day, split across three smaller meals to support consistent energy levels and healthy digestion. Saint Bernards have relatively modest activity requirements, which means overfeeding is a real risk; consistent portion control and low-calorie treats are advised. Feeding from an elevated bowl and avoiding vigorous exercise directly after meals can help reduce the risk of gastric dilatation-volvulus (bloat), which giant breeds are predisposed to. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
Portion sizes are approximate guidelines for a giant-breed dog. Adjust based on your dog's individual weight, age, and activity level. Always consult your vet.
