Great Pyrenees Puppy Nutrient Needs

The puppy stage is probably the most important life stage for dogs. This is particularly true for large-breed puppies. Large and giant breed puppies experience rapid growth, which must be considered. Otherwise, it can significantly increase the chances of developing orthopedic diseases such as hip dysplasia and patella luxation, which the Great Pyrenees is already susceptible to. All high-quality kibbles specifically designed for large-breed puppies have the optimum balance of calcium, phosphorus, vitamin D, and fat content. These nutrients are key to controlling bone growth. Nothing else will do. In fact, most general puppy kibbles state that they are not suitable for large-breed puppies.

The MSD Veterinary Manual recommends that all puppy kibbles should provide a minimum protein content of 22%. Because the Great Pyrenees has a much larger muscle mass, he should be fed kibble with a minimum protein level of 26%. This will provide him with all the amino acids he needs to develop. The Manual also recommends that a minimum fat content of 8% is best as well. This can come from Salmon oils and Chicken fat, which supports bone growth, a healthy coat, brain, and eye function. They help fuel all that puppy-growing power your Pyrenees will need.

A wide variety of vitamins and minerals are also key, either in the form of wholesome fruit and veggies or extra added supplements. These will support his developing immune system, which will ensure that he can fight illnesses effectively. Docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA) contribute towards healthy brain development and eye function. These nutrients are imperative during his puppy stage. They are crucial amino acids naturally present in mothers’ milk and are also in proteins, egg products, and fish oils.

Adult Great Pyrenees Nutrient Needs

When your Great Pyrenees pup reaches the age of 18 months, you need to start thinking about finding a suitable adult kibble. Again, you’ll want to find one that is specifically created for large and giant breeds. Be sure to slowly transition him to his new kibble. Otherwise, you risk upsetting his stomach, so follow the package instructions accordingly. This breed is prone to gastric dilatation and volvulus (GDV), commonly known as bloat. This happens when dogs eat too fast, and the stomach twists. It is painful and can be life-threatening.

Adult kibbles are lower in both protein and fats compared to puppy kibbles. The MSD Manual recommends that an adult dog be fed kibble containing at least 18% protein. However, the protein content should be at least 23% for larger breeds.

During adulthood, the focus of his nutrition should be a well-balanced diet. Healthy carbohydrates will provide him with energy, and wholesome fibers will keep him feeling fuller and prevent him from eating calorific and fatty snacks. It is particularly important to ensure that the Great Pyrenees does not become overweight. Too much weight will only add more pressure to his joints, creating further health concerns.

Ingredients that are rich in DHA, ARA, and EPA will ensure healthy brain function. Ingredients such as fish oil, flaxseed, and vitamin E will nourish his thick, fluffy white coat and support his joints.

Senior Great Pyrenees Nutrient Needs

From around the age of 7, your Great Pyrenees will join the senior’s gang. At this point, you need to slowly transition him to a senior kibble that will take care of his senior needs. Aging dogs, like older humans, become less active compared to their younger years. This means it’s important to lower the number of calories and carbohydrates that he eats. If he eats more carbohydrates than he burns, he will quickly become overweight. This can be dangerous for an elderly dog, especially for giant breeds.

A well-balanced diet is still necessary. But now, it’s more important than ever to ensure that the kibble you feed him has higher levels of glucosamine and chondroitin to support his aging joints. Meat meals, fish meals, and omega fatty acids are all rich sources of these ingredients, so be sure to look out for them.

A wide variety of vitamins and minerals will help to strengthen his aging immune system so that he can fight illnesses and diseases. Ingredients such as taurine and L-carnitine will look after his cardiac health and metabolism, respectively.

Your Great Pyrenees Puppy will need food that can help sustain his rapid growth requirements.

Great Pyrenees puppies between the ages of 8 weeks and 12 to 15 months do best on dry kibbles crafted for growing giant breed dogs.

As your Great Pyrenees ages, joint support becomes more important.

Once your dog hits around 8 years of age, you’ll want to start transitioning to senior dog food.

This means looking at foods that contain chondroitin or glucosamine to help keep joints healthy and extend their longevity.

As your Great Pyrenees ages, they will likely slow down. That means that calorie intake should be lessened compared to traditional adult food.
