How To Choose Dog Food for Giant Breeds

Giant dog breeds are genetically predisposed to bone problems. Therefore, you should ensure your large breed is getting proper nutrients for growth. So, you need to take note of the factors that will affect the food your dog should take.

High Source Of Proteins

Every dog needs proteins for regular metabolism, tissue growth, and repair. According to AAFCO, an adult dog’s protein requirement is about 18% of its diet, while a growing dog needs a minimum of 22%. A good dog meal for giant dogs needs to meet the minimum protein requirements.

Natural Source of Ingredients

Ensuring the source of ingredients for your dog’s food is all-natural holds a lot of benefits for your giant breed. Here are five of the benefits.

  • They are easier for your dog to digest
  • Natural ingredients reduce the risk of food allergies and skin problems in the long term
  • It improves the quality and longevity of life
  • Natural food promotes health and boosts immunity
  • Also, they have a rich flavor that your dog will enjoy

Fat Component of the Food

The fat component is more tricky because large dogs have a slow metabolism. They also have a higher risk of obesity; therefore, the fat content of their food should be moderate. A growing dog needs a minimum of 8.5%, and adults require 5.5% for maintenance.

The reduction of fats in their diets, however, causes dry skin and flaky furs. So, use foods with omega fatty acids to help keep their coats and skin healthy.

Fats are calorie-dense foods, and calories provide energy for rapid growth. Therefore, reducing fat intake reduces the amounts of calories available, and this leads to a well-paced growth.

Age of The Giant Breed

Like every other dog, different ages have varying dietary needs in giant breeds. The growth complications for big dogs change with age. Therefore, nutritional obligations for giant dogs also change with age. For the breed age, the focus will be the nutrient requirements for puppies and senior dogs.

For Puppies

The need for puppies is to avoid rapid growth without proper bone development. Another focus is to prevent skeletal problems by ensuring the right calcium-phosphate balance. The energy measured in calories is regulated to avoid unpaced growth.

Fat content in puppy food is reduced in giant puppy food to meet the average growth requirements while avoiding unnecessary bone problems. Controlling calcium-to-phosphate levels within a safe range is done by lowering calcium content.

Puppies also suffer from lactose intolerance, so dairy products do not need to be content of their food. The best food for puppies has less calcium, fewer fats, and no dairy products. When the time comes to switch large puppies to adult meals, it is always safer to do it later than too early. For a guide, on how and when to change, check here.

For Senior Dogs

Aging is not a disease, but in dogs like in humans, old age comes with health risks. Some age-related changes dogs experiences include cognitive dysfunction, arthritis, diabetes, dental, heart, and kidney problems, and cancer. They also experience decreased energy requirements and maintain good health. The best senior dog food for large breeds has the following attributes.

  • Highly digestible proteins to maintain muscle mass and prevent protein reserve depletion
  • Omega-3 fatty acids, glucosamine, and chondroitin improve joint health in all ages of giant breeds
  • A lower calorie content
  • High fiber content reduces the risk of constipation
  • Antioxidant-rich meals to boost immunity

When changing meals for senior dogs, consider their general health. If they are healthy and thriving, good adult dog food will be awesome.

Vitamins, Minerals, and Supplements

Some vitamins, minerals, and supplements are beneficial for your dogs, while some are not helpful in excess.

Beneficial Vitamins, Minerals, and Supplements

  • Glucosamine and Chondroitin are supplements that stimulate proper bone development and promote healthy joints
  • Phosphorus reduces blood calcium levels
  • Vitamin D metabolizes calcium and phosphorus

Minerals and Supplements to Avoid

  • Avoid multivitamins and food supplements that increase appetite or contain unnecessary vitamins. Dogs are sensitive to certain levels of vitamins and minerals
  • Your big dog breed can have 1.5% calcium in its meal. Because while giant dogs need calcium, excess calcium is not healthy for them

What is the Difference Between Large Breed Dog Food and Regular?

Differentiating FactorLarge breed dog foodRegular breed dog food

SupplementsOnly essential supplements to avoid overweightMultivitamins and food supplements to allow proper growth
Calcium contentLess calcium to ensure calcium-phosphate balance, and to reduce the risk of bone problemsOptimum calcium for cell functions

Apart from these main differences, most differences are slight. Just because a regular dog has a fast metabolism, doesn’t mean it should be eating on a caloric surplus. Regular dogs can also get obese.

What Should Large Breed Puppies Eat?

Large Breed puppies should eat food that is lower in calories and fat. Because large puppy breeds have a high tendency for exponential growth, they become big, not minding bone development. Large dogs are genetically at risk for bone and joint problems, and uncontrolled growth increases the risk. The best foods for giant breed puppies have reduced caloric content. Calories come from carbs, proteins, and fats. Limiting calorie content allows bones to grow while curbing the standard bodily growth rate. Because fat is a calorie-dense nutrient, large breed puppy meals reduce fat levels.

A calcium-phosphate balance should be maintained for healthy bones. Excess calcium can bind to phosphorus and decrease its absorption and vice-versa. Puppies cannot control the amount of calcium reabsorbed from their intestines. Therefore their food is meant to contain balanced calcium and phosphate to maintain healthy bones.

Any food your large breed puppy should eat has to consider these factors. One puppy food that takes note of these factors is Diamond natural’s large breed puppy lamb and rice formula. It contains appropriate calcium-phosphorus ratios for bone and joint development.
