- Caloric Content: 431 kcal/cup
- Type of Product: Low-Glycemic; Non-GMO

- Key Feature: High-protein dry dog food with limited carbohydrates for giant breed dogs
This formula is high in protein and fat for most adult St. Bernards. It also includes low-glycemic and complex carbohydrates to aid in digestion.
It offers calorie-dense food at 431 kcal/cup that fits most adult dogs’ needs. This comes from the 70% protein content the food offers, from sources like wild boar and deboned chicken.
With 18% Crude Fat, it’s higher in fat than is typically recommended for adult St. Bernards. But chicken fat and herring oil provide omega-3, omega-6, and omega-9 essential fatty acids. These aid in cognitive function, skin health, and healthy joints.
Instead of grains, this recipe includes pea fiber, dried carrots, and alfalfa meal. These easy-to-digest carbohydrates provide prebiotics for regular digestion and to keep your pup full.
Canine owners say this food is great for picky eaters. But some note that it’s not an excellent option for dogs who need a healthier diet higher in fiber.

This is a grain-inclusive formula. The whole grains include brown rice, oatmeal, and barley, which provide essential nutrients like B vitamins and magnesium. These aid in energy production and metabolic health.

It’s important to note that this is low-protein dog food, offering 20% Crude Protein. For large breed dogs, it’s recommended to provide at least 25%. Senior dogs may be able to get away with less due to decreased activity but talk to your vet about this before choosing this option.
This recipe supplements probiotics for aging digestive systems too. These offer good gut bacteria to fight against potentially harmful bacteria and keep the digestive tract clean.
Senior dog owners appreciate that the kibble size is slightly smaller and easy to eat for dogs with fewer teeth. But many say that for picky canines, you’ll need to add broth or a topper.

Rice and wheat gluten are the only grains included in this recipe. They provide easy-to-digest carbohydrates and minerals like zinc and magnesium. These boost immune system health and thyroid function.
Most vets don’t recommend canned food exclusively for large breeds since they’ll require a few cans per meal. But this is an excellent choice as a topper or special dinner. You can also mix it with dry food to make the kibble easier to eat.
Pet parents say their dogs slurp the gravy and love it when the food is added as a topper. But they hate the smell and say it can cause stinky farts.

How to Choose Food for Your St. Bernard
When choosing dog food for your St. Bernard, here’s what to look for.
High Protein
A diet with 25% Crude Protein or more per serving works well with St. Bernard dogs. The protein content helps build and repair muscles that help keep your pup in tip-top shape.
Plus, most protein options — including beef, fish, and chicken, and meat meals to name a few — contain taurine, glucosamine, and chondroitin. These nutrients are essential for heart and joint health.
Healthy Fats
Fats play a vital role in your dog’s diet — they provide them with energy.
Healthy fats from animal protein, meat meals, salmon oil, and flaxseed oil provide omega fatty acids for joint health, a healthy coat, and cognitive functioning.
However, to avoid extensive weight gain, a common issue for many St. Bernards, aim for food that offers 12% to 15% Crude Fat.
Carbohydrates and Fiber
Carbohydrates are the perfect addition to dog food for prebiotic fiber and nutrients like vitamin A and magnesium. These aid in gut health, strong eyes, and metabolic support. And prebiotic fiber also keeps constipation and diarrhea away.
But, be sure to choose easily digestible carbohydrates sources. Brown rice, oats, barley, and sweet potatoes are excellent. And if your dog needs a grain-free diet, focus on carbohydrates from peas, potatoes, and corn.
Vitamins and Minerals
Most commercial dog foods have the appropriate amount of vitamins and minerals that your dog needs.
But vitamins and minerals like vitamins B, C, D, and E, plus calcium and potassium, are crucial for St. Bernards.
These vitamins aid in energy production, immune function, and keep the skin clear and coat shiny. And vitamin D, calcium, and potassium are essential for giant breed dogs to keep healthy bones and avoid them becoming brittle and weak over time due to the dog’s size.
Ingredients To Avoid
Commercial dog foods are getting safer for dogs to eat since more research has come out recently about what to avoid feeding your pet.
While some additives can help preserve the food and fill up your furry friend, there are a few ingredients to avoid whenever possible. These include;
- BHA and BHT
- Artificial colors
- Artificial flavors
- Corn syrup
- Melamine
- MSG
These fillers can cause minor symptoms like tummy upset or dry and itchy skin. But others, like BHA and melamine, can cause kidney problems, liver issues, cancer, and even death in extreme cases.
Feeding Guide and Nutritional Needs
How much food do St. Bernards need?
Because they are a large breed and prone to problems with their weight and joints, they’ll require a high protein diet. Aim for at least 25% protein, although up to 35% is okay.
Because these canines can gain weight quickly, which causes joint and bone stress, keep fat under 15% unless your dog is active or under 18 months old.
Here’s how much they’ll need to eat.
Puppy
Puppies will need about 30 calories per pound that they will weigh in adulthood. St. Bernards average at about 120 pounds, so a puppy would need about 3,600 calories per day.
This should be split between three and five meals. Puppies should also eat a puppy-specific formula until they’re at least 12 months old.
Adult
In adulthood, you can keep your dog’s calories at 30 calories per pound if they work. If they live a sedentary lifestyle, lower this to about 25 calories per pound.
At the average size of 120 pounds, a less active dog would eat about 2,500 calories a day. These calories should be split between two meals, once in the morning and once at night.
Seniors
Senior dogs should eat even less, around 20 to 22 calories per pound, unless they’re active. This is to help avoid weight gain during their later years. They can still be fed twice a day.
Since St. Bernards are a large breed dog, their lifespan is shorter than those of small dogs. Because of this, they reach adulthood and their senior years fast.
You can switch your pup to adult food between 10 and 12 months. They reach seniorhood at around six years old, so you can switch to a senior formula by that age. Talk to your vet before changing since they may request switching faster or later.
Daily Amount of Food
Be sure to read the feeding instructions on any dog food you choose — they will typically have a chart on how much to feed your canine based on their age and weight. However, most St. Bernards will fall under the following categories.
Age | Serving Size |
---|---|
Under 3 Months | 2 cups, supplemented by mother’s milk |
3 Months – 4 Months | 3 cups |
4 Months – 6 Months | 3-4 cups |
6 Months – 1 Year | 5-7 cups |
1 Year – 5 Years | 8-9 cups |
6+ Years | 4-6 cups |
Health Problems in St. Bernards
St. Bernards are prone to problems that revolve around their size and weight. Because of this, it will be essential to keep your dog at the proper size and keep them active. But there are other health problems that they can be prone to. Here’s what you need to know.
Hip and Elbow Dysplasia
Like most large breeds, St. Bernards can suffer from hip and elbow dysplasia — especially as they age.
Hip and elbow dysplasia happens when the hip bone or elbow socket dislocates, and the bones rub against each other. This can cause extreme pain and lameness.
While this is usually caused by excess weight, it can also happen if your pup doesn’t have the proper nutrition during the first 12 months of their life.
To prevent this, feed them high-quality food with moderate fat content and omega fatty acids. These protect joint health. And exercise with your dog for at least 30 minutes a day.
Weight Control/Obesity
It’s easy for this giant breed to pack on the pounds. But lack of weight control can cause other health issues, including heart disease, hip dysplasia, and digestive problems.
To keep your pup at a healthy weight level, feed them the correct amount of food and calories according to their size. If they need to lose weight, talk to your vet about the appropriate diet and calorie amount they will need.
Also, keep your dog active. Daily walks, playing in the yard, and even swimming 20 to 30 minutes daily can keep the pounds off.
Bloat
Bloat, also known as Gastric Dilation Volvulus (or GDV), is when a dog’s stomach fills up with air or fluids. Their stomach will then fold and twist itself, which causes issues with digestion and the other organs around it.
Symptoms of bloat include a more pronounced belly, excessive gas, vomiting, and whining after eating. Extreme cases can cause death if not treated right away.
Any food can cause bloat, but feeding smaller meals and encouraging slow eating can keep it at bay. In some cases, you may want to switch your dog’s bowl to a slow bowl so they aren’t tempted to wolf down their food.
Osteosarcoma
Osteosarcoma is a bone cancer that is most commonly associated with giant breed dogs. While there aren’t any known direct causes, genetics may play a part.
This cancer is aggressive, so it must be found early to give your pup a better chance of beating it. Common signs include swelling and lameness in the joint areas.
Surgery, radiation, and chemotherapy are treatment options, and the tumor may be removed if found early enough. While diet won’t cover treatment, it can be an added benefit. Choose a food high in vitamin C, antioxidants, and vitamin D when possible. These help boost immunity and bone health.
Addison’s Disease
Addison’s disease is a hormonal disease where the body attacks the outer layer of the adrenal glands. This is caused by the lack of cortisol. It’s typically genetic and is common in female dogs.
Common symptoms include;
- Excessive thirst and potty breaks
- Strong pee odors
- Panting
- Rashes on the skin
This disease requires medication and treatment, like hormone replacement therapy. But a diet rich in healthy fats and slightly more sodium can be beneficial since they’ll aid in cortisol production.
Our Verdict
Due to their caloric needs and size, St. Bernards do well with a formula high in protein and calories.
We recommend Farmina Medium & Maxi Adult Grain-Free dry dog food. It offers the highest calorie amount per cup on the list and starts with real animal protein to protect muscle health.
While the other foods on this list are excellent choices, this is our favorite for St. Bernard adults.
