Large breed dogs have different nutritional needs than smaller dogs. Their food must support healthy joint development, maintain proper weight, and provide energy without causing them to grow too quickly.
The right dog food can help prevent common health problems that affect bigger dogs like hip dysplasia and bloat.
The best dog foods for large breeds contain high-quality protein sources, controlled calcium and phosphorus levels, and added glucosamine for joint support. Many brands now offer formulas designed specifically for large breed puppies and adults.
These foods typically have larger kibble sizes that encourage proper chewing and slower eating. They also balance calories to prevent rapid growth in puppies, which can lead to bone and joint issues later in life.
When choosing a dog food for your large breed, pay attention to the guaranteed analysis on the label and check that it meets AAFCO standards for large breed dogs.
Look for whole meat proteins listed as the first ingredient rather than meat by-products or fillers. The calcium-to-phosphorus ratio should be between 1:1 and 1.8:1 for proper bone development.

Nutritional support extends beyond basic protein needs. The formula includes vitamin E and other antioxidants to strengthen immune function.
Omega-3 and omega-6 fatty acids target skin and coat condition, whilst specific nutrients aim to support cardiovascular health in large breeds.
The wheat-free recipe avoids common fillers and artificial additives. You won’t find GMOs, artificial colours, or artificial flavours in this formula.

Harringtons Complete Large Breed Lamb & Rice
This lamb and rice formula provides solid nutrition for large dogs at a fair price point. The kibble size may not be as large as you expect.
Pros
- Includes glucosamine and chondroitin to support joint health in bigger dogs
- Made by a carbon-negative company that produces its own electricity
- Works well for dogs with sensitive stomachs
Cons
- The kibble pieces aren’t much larger than standard sizes despite being marketed for large breeds
- Contains wheat which some dogs may be sensitive to
- Limited to a single protein source in this formula
The Harringtons Complete Large Breed formula focuses on lamb and rice as its main ingredients. This combination tends to be gentle on digestion.
Owners report firmer stools and better appetite in their dogs. The food works across all life stages, so you won’t need to switch formulas as your dog ages.
Joint support stands out as a key feature in this recipe. Large dogs often struggle with joint problems as they grow.
The added glucosamine and chondroitin aim to keep their joints healthy. Big breeds put more stress on their bones and cartilage than smaller dogs.
The company makes all its food in the UK and has been family-run since 1923. They’ve also achieved carbon-negative status, which means they offset more carbon than they produce.
The 14kg bag offers good value compared to smaller packages. Some owners find the kibble size disappointing.
Whilst it’s labelled for large breeds, the pieces don’t differ much from regular kibble. Your dog can still eat it without problems, but if you’re looking for truly large pieces, this might not meet your expectations.
The food contains wheat, so it’s not suitable if your dog has grain allergies.
Buying Guide
Protein Content and Quality
Look for dog food with high-quality animal protein as the first ingredient. Large breeds need at least 22-26% protein to maintain muscle mass and support healthy growth.
Check that the protein comes from named meat sources like chicken, beef, or fish rather than generic terms like “meat meal”. Real meat provides better nutrition for your dog.
Balanced Fat and Calories
Large breed dogs need controlled fat levels between 12-15% to prevent excessive weight gain. Extra weight puts stress on their joints and bones.
The calorie content should match your dog’s activity level. Less active dogs need fewer calories per cup than working or highly active dogs.
Joint Support Ingredients
Your large breed dog benefits from glucosamine and chondroitin in their food. These ingredients help protect cartilage and maintain joint health as your dog ages.
Omega-3 fatty acids from fish oil also reduce inflammation in joints. Look for foods that list specific amounts of these ingredients on the label.
Calcium and Phosphorus Ratios
Large breed formulas need careful calcium and phosphorus balance. The ratio should be between 1:1 and 1.8:1 to support proper bone development without causing skeletal problems.
Too much calcium can lead to developmental issues in growing large breed puppies.
Life Stage Considerations
Choose food designed specifically for your dog’s life stage. Puppies, adults, and senior large breeds all have different nutritional needs.
Large breed puppy food should promote slow, steady growth rather than rapid development that strains developing bones.
