A giant dog’s required diet is drastically different from that of a tiny or medium-sized dog breed. Not only do they require a higher volume of food, but they need a variety of vitamins and nutrients to keep a healthy muscle mass and maintain proper organ function. They also have more energy to burn off on a daily basis, so you need to keep a healthy balance.

You may be familiar with a few giant dog breeds, including the Great Dane, Irish Wolfhound, Bernese Mountain Dog. The list doesn’t stop there, either, and you can view a comprehensive directory of the largest dog breeds on the American Kennel Club website.

A giant dog breed, in simplest terms, is any breed whose full-grown weight exceeds 99 pounds. This does not include overweight dogs who happen to fall beyond this weight range, but rather, breeds that are genetically engineered to weigh above 99 pounds.

Having a giant breed dog who is underweight or not receiving the proper diet can be harmful to their lifespan and overall quality of life.

Understanding a Giant Breed Dog’s Diet Requirements

Learning about your giant breed’s ideal diet and nutritional requirements is essential for raising and maintaining a healthy pup.

This is especially important if you’re raising a giant breed puppy. Giant breed puppies grow faster and longer than the average puppy, but their growth needs to be monitored in order to avoid dangerous health problems. Overfeeding a giant breed puppy or feeding them incorrect food can lead to uncontrolled growth spurts, causing painful bone, joint, and muscle issues in adulthood.

Most giant breeds won’t stop growing until two years of age or older. The “rapid growth” phase can occur anywhere between 4 and 8 months old, and their diet needs to be closely regulated and adjusted during this time.

Free-feeding your growing puppy is also dangerous because puppies do not practice portion control. They will eat whatever amount is in front of them without listening to their body, so overeating is very possible. You should feed your puppy multiple portioned meals per day to ensure proper growth and transition to an adult formula around 11 to 12 months.

  • Puppy Giant Breed Diet—As a puppy, you should feed a giant breed dog food containing at least 22-30% high-quality crude protein and approximately 10-14% fat. High-quality protein consists of whole-food meat or high-quality by-products, not meat meals including by-products.
  • Adult Giant Breed Diet—Full-grown giant breed dogs should be on a diet that includes a minimum of 22% protein and 10% fat.
  • Senior Giant Breed Diet—Diets formulated for senior breeds are still new to the canine nutritional market. Still, senior dogs need a lower calorie density food since they do not burn off as much energy and fat as younger dogs.

Calcium intake is also an important aspect of a giant breed’s diet. For puppies, a calcium: phosphorus ratio between 1:1 and 1:3 is the ideal range. Giant breeds react more to calcium, so the ratio is smaller than with other breeds. The calcium content in their food should be around 1.5%.

Giant breed adults, on the other hand, should be carefully monitored for signs of orthopedic disease, obesity, and bloat. Their diet heavily influences these conditions, so they need to be receiving a balanced formula with lots of beneficial vitamins and minerals.

Since giant breeds also have more muscle mass than smaller breeds, they will need to be fed a higher volume of food. Any dog food you purchase will have a recommended feeding chart according to weight, but most giant breeds will need to have a minimum of 4 to 5 cups per day. Your veterinarian can also help determine the correct diet for your pup.

Special Dietary Considerations for Giant Breed Dogs

The following health conditions are most commonly seen in giant breed dogs. They are very susceptible to musculoskeletal conditions that affect their movement.

Hip and elbow dysplasia: Malformed or poorly-fitting joints

Ligament damage


Wobbler Syndrome: Most common in Doberman Pinschers and Great Danes


Gastric Dilation Volvulus: Also known as bloating or torsion, occurs when the stomach suddenly fills with gas and twists

Dilated Cardiomyopathy: Irregular heartbeat, heart muscles not contracting fluidly

Aortic Stenosis: Aorta is narrowed, placing pressure on the heart

The list of diseases and conditions that are seen in giant breeds is much longer than what’s listed above, but these are some of the most common ones. While not everything can be fixed with a healthy diet, key ingredients will help strengthen certain organ functions and bone health.

A balanced diet for a giant breed puppy also prevents overfeeding and uncontrolled growth, which commonly leads to bone and ligament problems in adulthood.

Compared to their smaller cousins, giant dog breeds also have a significantly shorter lifespan. Some breeds, such as the Great Dane, Irish Wolfhound, and Pyrenean Mountain Dog, only have an average lifespan of 7-10 years. Staying on top of their diet and keeping them healthy is a big contributor to their overall health and dosage.

Organ function in giant breeds begins to deteriorate after five years when they become senior. Their energy is much lower as well, so they require a lower calorie intake. There are many foods specifically engineered for senior giant breeds.

If you obtained your giant pup from a breeder, ask to see their parent’s health information so you can be aware of any hereditary conditions you need to monitor and adjust for. If there are any, your veterinarian can help narrow down the best lifestyle changes to make.

Giant Breed Dog Feeding Chart

Giant breed dogs are canines that, when matured, weigh at least 99 pounds and are at least 30″ tall. In general, giant breeds require a diet with a lower caloric density. Larger dogs have slower metabolisms, so they need to consume fewer calories while still maintaining a heavier weight (so that means more food with fewer calories).

It’s hard to narrow down the number of calories per pound required because it varies per giant breed, age, and time of year. Most dog food brands will provide a feeding chart on the back of the bag to go by, or you can consult your veterinarian.

If you’re unsure about your dog’s weight and condition, consult a Body Condition Score (BCS) chart. Similar to a BMI score for humans, the BCS will allow you to gauge if your dog is underweight, overweight, or at the right weight. The ideal body condition score for a giant breed dog falls between 4 and 5.

Frequently Asked Questions and Giant Breed Feeding Guide

Here are the most commonly asked questions about formulating the ideal diet and schedule for giant breed dogs.

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

You should never feed your giant breed dog food that is formulated for small or medium-sized pups.

Giant breed dog food has many differences from regular dog food, such as having larger kibble sizes for larger mouths and a higher amount of glucosamine, chondroitin, and calcium because their bones and joints require extra support. Giant breeds also need a lower calorie density because they need to consume a higher volume of food than smaller dogs.

Is Protein Meal Bad for My Dog?

Chicken, turkey, lamb, and other protein meals are present in lots of dog foods. Opinions vary on protein meal, with some veterinarians advocating for it while others advise against it.

Protein meal is the dried end-product of rendering, a process that converts ground meat (typically including flesh, skin, and bone) into a concentrated powder that manufacturers use in their food. Meat meal can be a valuable ingredient in pet foods as real protein, such as deboned chicken, has a low protein and high water content, and using protein meal provides a higher concentration in a lesser amount of food.

Here’s what to look out for, though—you should stay away from any protein meal that includes by-products or is simply listed as “animal meal.” By-products include extra organs and materials that are not necessarily healthy for our pups, such as gizzards, bone, or even feathers. If a dog food you’re considering includes a type of protein meal, but they don’t use any by-products, it’s perfectly healthy for your dog.

Should Giant Breed Dogs Be on a Grain-Free Diet?

Recently, the FDA released a report exploring the relationship between grain-free diets the increase in canine dilated cardiomyopathy (CDM). The results were not conclusive, but this sent many dog owners into high alert about their dog’s diet and whether or not grain-free is the way to go.

While grains contain a high amount of carbohydrates and are linked to enlarged hearts in humans, this is highly unlikely to occur in our lovable, furry family members. The absence of grains in dog food usually means they’ve been replaced with another supplemental ingredient such as peas, lentils, or sweet potatoes, which are actually higher in carbohydrates than traditional grains.

If your dog doesn’t have any food sensitivities, then you should have no reason to specifically seek out grain-free food. Grain-free does not mean it’s a healthier recipe. If you have any concerns about your dog’s weight, then you can always consult the Body Condition Score (BCS) chart and go to your veterinarian with any outstanding concerns.

Raw and fresh dog food is naturally grain-free because of the selection of ingredients used. This is perfectly safe for your pup because it does not have any substitutes mentioned above, like peas or lentils. The formula composition is entirely as nature intended.

How Often Should I Feed My Giant Breed Dog?

Growing puppies should receive three small meals per day, and adults and seniors should be fed twice a day. Puppies do not practice portion control so you should never leave food out for free-feeding. While grown dogs practice some degree of portion control, there is still a very high risk of overfeeding and becoming overweight, resulting in a number of health concerns.

How Do I Transition My Giant Breed Dog to a New Food?

If your pup is already on a regulated diet and you’ve decided to introduce a new food, under no circumstance should you switch their food entirely in one day. This can cause many issues, such as puking, loose stool, and stress.

For healthy dogs, the ideal diet transition includes:

  • Day 1: 25% new diet and 75% old diet.
  • Day 3: 50% new diet and 50% old diet.
  • Day 5: 75% new diet and 25% old diet.
  • Day 7: 100% new diet.

If your dog has a sensitive stomach, food allergies, or any other gastrointestinal problem, they will need a longer transitional period. The key to a smooth transition is to constantly monitor your dog’s health. If they begin vomiting or have diarrhea, you should cut back on the newer food and lengthen the process.

It’s also a good idea to buy the smallest amount possible of the new dog food in case your dog has an adverse reaction, and you cannot use the rest.

What is AAFCO?

AAFCO stands for the Association of American Feed Control Officials. The AAFCO does not approve or disapprove of any individual dog foods, but they have a set guideline for nutritional levels that ensure a healthy diet for specific types of dogs at different ages.

Each manufacturer is required to meet these guidelines on their own. To ensure that they meet AAFCO standards, a statement that looks like this will be present on the bag, typically near the ingredients:

[Dog Food Brand and Recipe] for [Adult Dogs/Puppies] is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for maintenance.

Which Fruits and Vegetables are Best in a Giant Breed Dog Food?

Fruits and vegetables are a necessary source of vitamins and minerals and typically provide a better concentration than artificial additives. The following fruits and vegetables are best in giant breed dog foods:

  • Apples
  • Cranberries
  • Pumpkin
  • Kale
  • Carrots
  • Broccoli
  • Beets
  • Celery

The list doesn’t stop here, but you should be aware of the benefits that each ingredient provides. Apples, cranberries, and pumpkin are known for their anti-inflammatory properties. Beets help with digestion, skin, and coat, and kale provides a number of health benefits such as bone health, increased vision, and immune function.

Giant Breed Dog Food – A Final Word

Now that you know the basics about your giant breed dog’s nutritional and dietary needs, you’re ready to narrow down the best giant breed food for your pup. Giant breeds need extra joint and muscle support, as well as an overall lower calorie density.

Foods that start with real, all-natural protein and include lots of vitamins and minerals are the best choice. Be wary of any food that includes a protein meal that includes animal by-products. If you’re still not sure where to start in choosing the best food for giant breed dogs, try one of our top 15 picks reviewed above!
