The 10 Best Dog Foods for St. Bernards

1. The Farmer's Dog Fresh Dog Food Subscription – Best Overall

The Farmer’s Dog recipe is formulated and designed by a team of board-certified veterinary specialists. Other brands use computer programs to verify nutrient content, but The Farmer’s Dog is tested using a method superior to AAFCO’s system by conducting live feeding trials on dogs of multiple ages and breed sizes over a 6-year period. This means the recipes are nutritious for all ages and breed sizes, including the largest breeds like the St. Bernard.

USDA human-grade beef is the first ingredient in this recipe, with extra nutrition from beef liver. The recipe has a high-calorie count, which isn't suitable for all dogs. It includes fish oil, which is a natural source of omega-3 fatty acids and excellent for joint health. It also contains sweet potato for healthy digestion and the superfood kale, which is one of the healthiest greens and is packed with vitamins and minerals.

The Farmer’s Dog is the best overall dog food for St. Bernards. It is only available to order, which means they are tailored to your dog’s specific needs. For a large dog, it means the food will take up a lot of space in your fridge and freeze.

2. American Journey Active Life Dog Food – Budget Buy

American Journey has superfoods like cranberries, which can promote bladder health, and dried kelp, which is iodine-rich and rich in natural salts and minerals to boost your dog’s overall health.

There is never any corn, soy, or wheat in American Journey’s formulas, and it is the most reasonably priced brand, which makes it the best dog food for St. Bernards for the money.

This recipe has a slightly high carbohydrate rate content (35–40%) which is worth noting.

4. Hill’s Science Diet Large Breed Puppy Food

Hill’s Science Diet Large Breed provides your large puppy with the precise nutrition for growing and getting into mischief. Lamb meal is the first ingredient and a meat concentrate containing nearly 300% more protein than fresh lamb.

There is also chicken fat in the recipe, which is a potential allergen that might not be entirely obvious initially because it is the lamb recipe. There is also an egg product that is high in protein and an excellent source of fatty acids and vitamins. Dried beet pulp is also present, and it’s a controversial ingredient because it’s a high-fiber by-product. However, it benefits blood sugar and intestinal health and is perfectly safe in dog food.

Buyer's Guide: Choosing the Best Dog Food for St. Bernards

You might feel stressed about your choices, but we have some tips for you to consider when choosing a diet for your St. Bernard.

How Do You Know Which Diet Is Best?

Your best resource is the internet. Research a brand or recipe that stands out the most to you and see what other owners say about it. You need a brand that maintains your St. Bernard’s health, is tasty, affordable, and easy to find online or in stores. Some dogs have sensitivities and allergies, while others are fussier with flavors. Research your preferred food and see if it can satisfy your dog’s specific needs.

With a large breed, you have to store large bags of food. Start small when changing to a new diet, in case your dog doesn't like the new food. Also, be aware that if the dog food isn't stored properly, it can become infested with insects.

Large Breeds and Weight Gain

St. Bernards have large, stocky bodies and are more prone to joint problems like hip dysplasia than other breeds. This can harm their mobility and affect their energy, which in turn causes them to gain weight.

If you’re ever unsure about your dog’s weight management, contact a vet for advice.

Healthy Protein and Fats

Not all ingredients are equal. Choose high-quality meat proteins and stay away from by-products and meat meal. If the ingredients are concentrated sources of protein, they will appear as “salmon meal” or “chicken meal”. They are excellent protein sources, and you don't have to worry about them, but avoid food that contains “meat meal”. If it’s unnamed, it’s best to avoid it, and that goes for by-products too.

A fat to avoid would be something like canola oil, whereas fish, eggs, salmon oil, coconut oil, or flaxseed oil are much better fats. You also want a diet that is high in omega fatty acids and glucosamine concentrations since they promote heart and joint health.

High-quality ingredients will cost you more, but choosing lower-quality ingredients could result in health problems that will shorten your dog’s life and also potentially cost you more in vet bills in the future.

Digestible Carbohydrates

Carbohydrates should always appear in moderation because too many can cause weight gain. High-quality carbs provide fiber for digestion, like potatoes, sweet potatoes, chickpeas, or quinoa. These ingredients are rich in vitamins and minerals like potassium which supports your dog’s nerves, heart, and muscles.
