Saint Bernard Puppy Nutrient Needs

Giant dog breeds are dogs that, at maturity, weigh 100 pounds and upwards. As the Saint Bernard will weigh anywhere between 120 and 180 pounds, you need to find him a kibble specifically designed for large or giant dog breeds. This is essential during his developmental stage because they will help control his rapid bone growth. And this will lower the chances of him developing bone diseases such as hip dysplasia.

A well-balanced diet is crucial, as this will ensure that each of his nutritional needs is catered for. High-quality giant breed puppy kibbles will provide this. He’ll need vitamins and minerals to strengthen his developing immune system, from fruits, veggies, and supplements. He’ll also need prebiotic fiber and probiotic ingredients to keep his digestion regular and hopefully reduce the infamous Saint Bernard flatulence.

Omega fatty acids, docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) are an essential part of his diet too. Not only will they nourish his skin and coat, but they will also help his organs to function well and improve his overall wellness. Ingredients such as meat meals, fish oil, animal and plant fats, flaxseeds, and eggs are the best sources for these nutrients.

Protein is another crucial component of healthy development. They provide essential building blocks for a healthy body and lifestyle. To achieve the best quality protein, always look for real meat as the first ingredient. The Association of American Feed Control Officials (AAFCO), who set the guidelines for pet nutrition, state that all puppies need a protein content of at least 22%.

Adult Saint Bernard Nutrient Needs

Many giant dog breeds fully mature between the ages of 12 and 24 months. It is advised that between the ages of 12 and 18 months, you should slowly switch your Saint Bernard to an adult formula. And again, one that is designed specifically for large or giant breeds. Large dogs need fewer calories per pound of weight, and their joints need more support, so general kibble will not do.

During adulthood, his focus should be on a well-balanced diet to ensure that he gets everything he needs. At this stage of his life, AAFCO recommends that all adult dogs need a protein content of at least 18%. In addition to this, he will need healthy carbohydrates, prebiotic fiber, omega fats, vitamins, and minerals. If he has any dietary needs, be sure to focus his nutrition on these.

As you probably already know, Saint Bernards are greedy giants. And because of this, it’s easy for him to put on weight. Always follow package instructions and do not overfeed him no matter how much he paws for more. If he becomes overweight, you should switch him to a weight management kibble. There are two great options at the end of this guide.

Senior Saint Bernard Nutrient Needs

At around the age of six to seven, you will need to think about switching him to a senior kibble. Older Saint Bernards are much less active than teenagers, requiring less energy, calories, and fats. And senior kibbles provide less of these and instead replace them with low-calorie fiber. This will keep him feeling fuller for longer and help to manage his weight.

Don’t skip on the healthy fats, though, as he still needs these. Healthy omega fatty acids will keep his cognitive function up and support his cardiac and coat health. He also needs glucosamine and chondroitin to support his heavily laden joints. Ingredients such as meat meals will provide these, as well as extra added supplements. Also, look for extra vitamins and minerals to support his weakening immune system.

Best Food for Saint Bernard Puppies

Puppyhood is one of the most crucial growth windows for Saint Bernards.

During your Saint Bernard’s first year, they will need a puppy food that’s higher in calories and nutrients to meet the demands of their quickly growing body. The nutrient needs of a Saint Bernard puppy are not different from the Mastiff or Great Danes, both giant breeds as well.

These pups spend most of their day sleeping so their bodies can grow. You’ll need a balanced dog food for giant breed puppies, to make sure that your pup meets their growth potential. Each of the foods below will do that. Let’s look at some of our favorites for Saint Bernard Puppies.
