Dog eating dog food
Choosing the right food for your diabetic dog could mean a world of difference for their health.

To find the best foods, we first did extensive research into the most reputable brands of food that were specifically formulated with diabetic dogs in mind, like Merrick, which is known for using only the best whole foods and high-quality ingredients.

We even looked into prescription diets such as Royal Canin, which is highly regarded by vets and customizable to your dog’s needs.

Real dog opinions are essential, so we searched for food brands with the best dog and owner reviews and researched the specifics for dozens of dog foods to see which ones showed the best results. 

Finally, we tested the best ones and narrowed down the best dog foods to our top 5 picks. There were several other good options to choose from, so we included an honorable mentions section for foods that didn’t rank at the top.

We love that this formula is grain-free and packed with just the right amount of good fats for your pup’s optimum health. The omega-3 and omega-6 fatty acids help the skin and coat.

Based on our research, Orijen is a highly reputable brand known for producing biologically-appropriate foods ideal for a range of applications. This formula is derived from chicken, turkey, and wild-caught fish, and our dog loves these flavors.

We know the first 3 ingredients in your pup’s food are super important, so we love that all of these ingredients will provide lots of protein to promote lean muscle growth without piling on fat.

The food is made from real animal ingredients, so you’ll be giving your dog a taste of the wild. These include meat, cartilage, and bone pulped down into lip-smacking dry dog food. Your dog won’t know it’s on a diet.


One of the key points we found great about this brand is that formula is made using raw ingredients with all the nutrients intact. This is ideal for all life stages and breeds, and this food was well worth trying out if you need to switch up your dog’s food because of canine diabetes.

When you’re transitioning your dog to this food, the manufacturer recommends doing so gradually over a two-week period. Start by introducing 25% Orijen with 75% of his old food, then gradually change the ratio to include more Orijen over the following 14 days.

• Antioxidants for a strong immune system
• Comes in a variety of bag sizes
• High protein, low carb content

What We Didn’t Like

• You’ll need a pet prescription to purchase food
• Brand doesn’t offer a grain-free version


Royal Canin is a highly reputable brand, so how does this dry dog food from their Veterinary Diet line compare? Firstly, this is a dedicated Glycobalance formula designed to support dogs with diabetes, so you’ll be getting a specialized solution from a company you can trust.

We like that the food is loaded with protein while maintaining a reduced level of starch. This will help your dog pack on some lean muscle without straying into obesity. Our lucky test dog for this formula gave it a tail-wagging positive review for flavor.


The formula is packed with antioxidants ideal for strengthening your dog’s immune system. You will need a pet prescription for this food, but this can be uploaded and verified at the time of purchase, so don’t let this put you off.

While making general modifications to your diabetic dog’s diet can pay dividends, buying dedicated diabetic food gives you an even stronger chance of successfully managing your pup’s condition.

When transitioning your pet to any new food, mix a small amount of new food with old food. Use two weeks to slowly introduce more and more of his new food until he’s fully transitioned.

How to Choose Which Brand is Right for Your Dog

Consider Your Dogs Needs

Each dog has its own unique set of needs based on activity level and personality. With the help of your vet, it’s best to determine how much protein and carb/fat levels will help your diabetic dog feel its best and then compare that with the contents of each food.

There isn’t a replacement for veterinary care when managing canine diabetes. Your vet can give personalized food recommendations that will help your dog thrive while managing diabetes.

What’s Your Budget?

We’re all on our own budgets, so considering how much you can spend and what’s a reasonable price for your budget is key. Consistency is best when it comes to your pup’s diet, so it’s best to choose the food you can afford long-term.

What’s Your Dog’s Flavor Preference?

Each pup has a unique palate, and some are pickier than others. Before purchasing diabetic dog food, consider flavors you know your pup likes and will eat. There isn’t much point in buying diabetic dog food that you know your dog won’t like.

Honorable Mentions

Here are two options we considered but ultimately didn’t make our list.

1.  Nutrisca Grain-Free Dry Dog Food 

Nutrisca uses high protein sources such as chicken and chicken meal, but ultimately the formula contained too much plant protein, and the ingredients were not as well-sourced.

While the Merrick grain-free dog food also uses some plant sources for protein, ultimately, it has a higher-quality formula for a better price point, making it our top choice with the bonus of better affordability.

2. Ketona Dry Dog Food 

We liked that Ketona dog food works well for diabetic dogs because of its low carb and high protein content. However, this brand had quite a few negative reviews about it making their dogs lethargic, so we had to recommend Nulo dog food over its competitor.

Both brands are similar, but we want only to recommend the best dog foods for diabetic dogs that we believe are the healthiest and best for your dog.
