The Saint Bernard is a giant-breed dog (54 to 82 kg) with low energy and a calm temperament. The Merck Veterinary Manual lists the breed among those predisposed to dilated cardiomyopathy (DCM), with taurine deficiency as an associated nutritional factor. While he grows, controlled calcium (up to 1.8% of dry matter) protects the puppy's joints.
In the current My Pet Magazine analysis, the best food for the Saint Bernard is Purina Pro Plan Complete Essentials (Purina Pro Plan), with a technical score of 91.7/100 (🌟 Superior Quality), calculated with the My Pet Magazine IDNM/IPFI methodology across 49 dog foods reviewed in July 2026.

What to weigh in food for the Saint Bernard
The Saint Bernard has two issues that weigh in the choice of food, and both demand extra attention because he is a giant breed.
Heart. The Merck Veterinary Manual lists the Saint Bernard among the large/giant breeds predisposed to dilated cardiomyopathy (DCM). That makes it relevant to check whether the food provides taurine and L-carnitine, nutrients associated with the heart's muscle function, and to avoid formulations with a history of association with cases of nutritional dilated cardiomyopathy — always with follow-up by a veterinary cardiologist.
Joints and growth. Being a giant breed, the Saint Bernard has accelerated bone growth that demands rigorous calcium control while the dog is still developing. FEDIAF limits calcium in large/giant-breed puppy food to 1.8% of the dry matter of the food, so as not to speed bone gain beyond what the forming joints can support. In adult life, the care shifts to continuous cartilage support, with EPA, DHA and chondroprotectives.

Breed profile and predispositions
The Saint Bernard carries two well-documented predispositions, and each one calls for different nutritional care.
The first is cardiac: the Merck Veterinary Manual — Dilated Cardiomyopathy in Dogs and Cats lists the Saint Bernard among the breeds "particularly at risk" of dilated cardiomyopathy, alongside the Doberman, Boxer, Great Dane and Labrador. The source points to taurine deficiency among the nutritional causes of the disease — which reinforces the relevance of taurine and L-carnitine in the diet as support for cardiac function, and of avoiding formulations associated with cases of nutritional DCM.
The second is orthopedic: being a giant breed with rapid bone growth, the Saint Bernard has a high prevalence of hip and elbow dysplasia, according to breed orthopedic screening statistics. The FEDIAF 2024 guidelines set the calcium limit at 1.8% of the dry matter of the food for growing large/giant-breed dogs — above that, excess calcium speeds bone formation beyond the pace the joints keep up with.

Frequently asked questions about Saint Bernard food
- Does the Saint Bernard need a special food?
- He needs attention to two things: the heart and the joints. The Merck Veterinary Manual lists the Saint Bernard among the giant breeds predisposed to dilated cardiomyopathy, and the puppy's accelerated growth calls for controlled calcium to protect hips and elbows. A good food for a Saint Bernard provides taurine and L-carnitine for the heart, and calcium in the right measure for the joints.
- Why does the Saint Bernard's heart need so much attention?
- Because the Merck Veterinary Manual lists the Saint Bernard among the breeds at risk of dilated cardiomyopathy (DCM), alongside the Doberman, Boxer and Great Dane. The source itself points to taurine deficiency as one of the nutritional causes of the disease — which is why taurine and L-carnitine in the food gain relevance, always with follow-up by a veterinary cardiologist.
- Why does calcium in the food matter so much for a Saint Bernard puppy?
- Because it is a giant breed that can exceed 80 kg as an adult, and the puppy's body does not handle extra calcium well during growth. Excess calcium speeds bone formation beyond the pace the joints keep up with. FEDIAF limits calcium in large/giant-breed puppy food to 1.8% of the dry matter of the food.
- Is the Saint Bernard at risk of dysplasia?
- Yes, it is one of the giant breeds with the highest prevalence of hip and elbow dysplasia, according to breed orthopedic screening statistics. Calcium control during growth and support with EPA, DHA and chondroprotectives in adult life help protect joints that already carry a high body weight.
- Is the Saint Bernard a high-energy breed?
- No. It is a low-energy breed with a calm temperament, even though it is giant. That calls for caloric density matched to a calmer dog — without overdoing it, because extra weight overloads both the heart and the joints, the breed's two sensitive points.
