Diabetic Dog Food FAQ

dog and bowl of food

What foods can diabetic dogs eat?

According to the American Animal Hospital Association (AAHA), the type of diet that a diabetic dog follows is less important than the consistency of that diet.

Focus on a high quality, balanced diet. The macronutrients that your diabetic dog needs to thrive should be provided in the following ratio:

  • 40% of total calories from a proteins source
  • 45% of total calories from carbohydrate sources (35% cooked grains plus 10% vegetable and/or fruit)
  • 15% of total calories from a supplemental fat (oil) source.

In addition, the following micronutrients should be added:

  • Sodium Chloride (table salt) and/or potassium chloride (salt substitute), depending upon the ingredients used in the meal.
  • Bonemeal and a multivitamin and mineral supplement.

What is the best food for a diabetic dog?

To answer the question of what is the best food for a diabetic dog. Let’s consider each of the macronutrients, one at a time.


proteins provide the building blocks, in the form of amino acids, that are necessary for growth, maintenance, and repair of tissues, organs, blood, and hair.

It is especially important for your diabetic dog to get a plentiful supply of quality protein because, in the absence of glucose, the muscle cell will use up protein as an energy source.

Proteins are made up of essential and non-essential amino acids. Dogs can produce non-essential amino acids through normal bodily functions.

However, they cannot meet their requirements for essential amino acids on their own – it must come through their diet.

The best sources of protein for your diabetic dog are:

  • Meat
  • Poultry
  • Fish
  • Eggs
  • Organ Meat
  • Some dairy products, such as cottage cheese

All foods contain some protein. But there are huge differences in protein quality.

You want to feed your diabetic dog proteins that are easily digestible, as dogs have short digestive tracts.

The protein should also be complete, meaning that it should contain all of the essential amino acids. Most animal proteins meet this criteria.

Plant-based proteins are incomplete, as they lack a number of amino acids.

In order to create a complete protein, plant-based proteins must be combined with a carbohydrate, such as brown rice, to provide the complete range of amino acids. 

Plant-based proteins are also difficult for dogs to suggest. As a result, we don’t feel that plant-based foods are a good source of protein for dogs.

Carbohydrates are broken down by the digestive system and converted to glucose to be used for energy.

Your diabetic dog is unable to naturally produce the insulin that is needed to transport the glucose into the cells of its body, requiring the use of external insulin.

But it still needs a constant supply of glucose in the form of carbohydrates. Carbs also supply fiber, which aids gastrointestinal functioning.

The best form of carbs for your diabetic dog are:

  • Cooked whole grains, such s brown rice, oatmeal and barley
  • Whole wheat flour products
  • Vegetables and fruits

There are some important points to keep in mind when feeding carbs to your diabetic dog. Too many carbs can cause gas, diarrhea, or weight gain.

Grains must be cooked for your dog to be able to properly digest them.

Brown rice is the best cooked grain, being rich in nutrients and easily digestible. Puree raw fruits to make them easily digestible, but leave the skin on.

Remove any pits or seeds as they may be toxic or cause the dog to choke.


Fats are highly concentrated forms of energy. They supply essential fatty acids and serve as carriers for the fat-soluble vitamins: A, D, E and K.

Fat deposits in the body protect and stabilize various internal organs as well as insulating the body from cold.

In addition, fats add flavor to food. It is important to keep a close eye on the amount of fat in the diet of your diabetic dog.

That’s because fat contains more than twice as many calories as either protein or carbohydrates.

Too much fat can also lead to such serious health problems as obesity and pancreatitis.

Fats supply essential fatty acids, which have a key role in doggie health. Dogs need linoleic acid, the main fatty acid in a category of polyunsaturated fatty acids (PUFAs) known as omega-6.

Omega-6 fatty acids play an important role in skin and coat health, tissue repair, immune system response and reproductive function.

Dogs need to get linoleic acid in their diets because it cannot be manufactured by the body.

A dog that is deficient in essential fatty acids will be more susceptible to skin disorders, coat problems, and infection.

Vegetable oils, such as safflower and canola, are good sources of linoleic acid.

Some meats, such as the dark meat, fat and skin of chickens, are also good sources of linoleic acid. Look for recipes that use lean meats with canola oil added.

Can nondiabetic dogs eat diabetic dog food?

Yes, non-diabetic dogs can eat foods that are listed as diabetic.

The foods that a diabetic dog should be eating are the same as what all healthy dogs should also be consuming; high-quality lean proteins, low glycemic index carbs and quality fats or essential fatty acids and linoleic acid.

What vegetables are good for diabetic dogs?

vegetables good for dogs

Here are a half dozen fantastic low glycemic index vegetables that your diabetic dog will love:

  • Winter Squash – winter squash vegetables are great for diabetic dogs mainly due to their high fiber content. Vegetables in this category include pumpkins, acorn squash, butternut squash. Just make sure that these vegetables are cooked well before serving up to your pooch.
  • Alpha Sprouts – this is another food that is high in fiber and dog friendly. Mix raw alpha sprouts with oats or rice, along with some lean meat cuts to provide the ideal nutrient balance.
  • Carrots – the naturally occurring sugars in carrots are not going to affect your diabetic dog’s insulin levels. Carrots are full of nutrients, safe and easy for your dog to digest when they are pulped.
  • Parsley – parsley is a green leafy vegetable that is, once again, high in fiber. It is also very low in sugar.
  • Fresh Garlic – fresh garlic is fantastic for the digestive tracts, in humans and dogs. However, you need to be sure not to overdose on garlic, as it may cause anemia.
  • Broccoli – broccoli is a high fiber food that is very low in sugar, which puts it way down on the glycemic index.
  • Green Beans – green beans are a high fiber food that is low in carbs. Serve your diabetic dog raw green beans but be sure to pulp them up thoroughly.
  • Leafy Salad Greens – this category includes such vegetables as collard greens, kale, mustard greens and romain lettuce.
  • Pea Pods – The entire pea pod contains beneficial nutrients for diabetic dogs. The pod is very rich in fiber.
  • Beets – beets provide important phytochemicals that add to the health of your diabetic dog. They can be served either raw or cooked.

Can diabetic dogs have treats?

Yes, you can provide treats for your diabetic dog. However, you should make sure that you are serving up healthy treats that are low on the glycemic index and low in calories.

It is often a good idea to treat your dog after he has his inulin shot each day. Focus on vegetable treats like sliced up carrots, sweet peas, green beans, and apples.

Of course, you can also provide your diabetic dog with non-food treats.

Taking him for an extra walk or spending an extra 10 minutes of one-on-one play-time will be more rewarding to our dog than throwing him an extra biscuit.

Do diabetic dogs need supplements?

dog eat kibbles from bowl

Yes, diabetic dogs should take supplements. In fact, all dogs should do so.

Even though your commercial product tells you that it is nutritionally complete, there is still a chance it is not providing everything your dog needs to stay healthy.

Many veterinarians need recommend vital supplements for puppies to make sure they receive everything they need during their critical growth and development stage.

Puppies are susceptible to getting worms, which is potentially deadly, so supplementation can be a lifesaver for some puppies.

Aging dogs are more likely to experience health problems that impact the immune system. That means it is less able to fight off free radicals and toxins that cause disease.

Older dogs are also able to absorb nutrients from their food, and some of them tend to eat less. So, supplements with various nutrients can be especially beneficial for older dogs.

Before giving your dog any supplement, you should check with your vet. Dietary supplements that are popular for use in dogs to treat specific conditions include the following:

  • Glucosamine, chondroitin sulfate, MSM (methyl-sulfonyl-methane) and yucca to help in joint health and the management of arthritis.
  • Vitamin C, vitamin E, beta-carotene and selenium. These antioxidants protect against free radical damage.
  • Omega-3 fatty acids to aid in the treatment of skin disease.
  • Probiotics to provide good bacteria to improve digestion

Look out for manufactured diabetic dog food formulas that include some of these supplements in their formula

Can you help me to read dog food ingredient labels? They are quite confusing!

labels on dog food

Dog food labels must list the ingredients in decreasing order by weight (on a dry food basis) rather than by amount or volume, starting with the heaviest item.

So, if you read a label and the first four items are beef, corn middlings, corn gluten, and corn meal, you would think that the product contains a lot of beef.

But beef, like chicken, turkey, fish, and lamb are whole food sources that consist of about 75 percent water, so they are naturally heavy.

So, our example actually represents a corn-based product that has some beef in it.

The manufacturer has purposely deceived the public by dividing the corn into three different ingredients so that they can list beef first.

There are dozens of ingredients you need to understand in the quest for healthy food for your dog. These involve meat by-products, meat meals, grains, vegetables, cheap fillers, and chemicals.

Pet food makers must list the preservatives they put in their products, but they do not always reveal preservatives in ingredients that are processed somewhere else and added to their product.

Here is a list of artificial additives, preservatives, and chemicals that should not be listed on the food you choose for your diabetic dog:

  • Animal digest
  • Animal fat
  • Artificial colors and flavors
  • Beet pulp
  • Blood meal
  • BHA/ BHT
  • Corn
  • Corn bran
  • Corn gluten meal
  • Corn syrup
  • Ethoxyquin
  • Fish meal
  • Gelatin
  • Hulls
  • Meat meal
  • Mill run
  • Natural flavors
  • Propylene glycol
  • Poultry by-product meal
  • Rice gluten meal
  • Soybean meal (de-hulled, solvent extracted)

Rather than these ingredients, look for dog foods that are preserved with Vitamin C (ascorbic acid), vitamin E (mixed tocopherols), or plant ingredients such as rosemary.

These natural ingredients do not preserve dog food as long as chemicals do, so make sure to check the expiration date on any dog food that contains natural preservatives.

You should also avoid foods that contain meat by-products, especially those with the ambiguous term ‘meat’ rather than a specific source.

‘Meat meal’ may also contain meat by-products and are also to be avoided if at all possible.
