If your dog has been diagnosed with diabetes, you may be wondering what you can do at home to support their health. While diabetes requires some veterinary care and, for many dogs, insulin therapy, nutrition also plays an important role in helping manage blood glucose, body weight, and overall health.
At Tail Blazers, we believe the food in your dog’s bowl matters. Our approach is to choose foods made with quality, species-appropriate ingredients and to avoid unnecessary fillers, artificial additives, and highly processed ingredients whenever possible.
Understanding Diabetes in Dogs
Diabetes mellitus occurs when the body cannot properly regulate blood glucose because there is not enough effective insulin. Without adequate insulin, glucose cannot be properly moved from the bloodstream into cells for use as energy.
Common signs of diabetes in dogs can include:
- Increased thirst
- Frequent urination
- Increased appetite
- Unexplained weight loss
- Weakness or reduced energy
- Recurrent infections
- Cataracts or changes in vision
- Wounds that heal slowly
If you notice these symptoms, your dog should be examined by a veterinarian. Diabetes can become serious if it is not diagnosed and managed appropriately.
Why Nutrition Matters
Dogs do not have a dietary requirement for carbohydrates in the same way that they require essential amino acids and fatty acids. Carbohydrates can be broken down into glucose, which is particularly relevant when managing a dog with diabetes. When a dog eats a carbohydrate-containing food, digestible carbohydrates are broken down into glucose. That glucose enters the bloodstream after the meal, causing blood glucose to rise. In a healthy dog, the pancreas responds by releasing insulin, which helps move glucose out of the bloodstream and into cells where it can be used for energy.
A diabetic dog has a very different situation. Dogs with diabetes have a deficiency of insulin due to loss of insulin-producing cells. Without sufficient insulin, the body has difficulty moving glucose from the bloodstream into cells, resulting in persistently elevated blood glucose.
Therefore, food matters! For diabetic dogs, the goal isn’t simply to find a food labelled “diabetic.” The overall nutritional profile matters, including the amount and type of carbohydrates, protein, fat, fibre, calories, and moisture.
We encourage pet parents to look beyond the front of the bag and examine the actual ingredient list.
What About Prescription Diets?
Many veterinarians will recommend a diabetes specific prescription diet. However, not all therapeutic diets are created with the same ingredient philosophy that we use at Tail Blazers.
For example, take Royal Canin Canine Glycobalance dry dog:
Ingredients (June 2026): Chicken by-product meal, barley, pea fiber, wheat gluten, corn protein meal, chicken fat, dried plain beet pulp, tapioca, powdered psyllium seed husk, potassium chloride, marine microalgae oil, calcium carbonate, salt, vitamins [DL-alpha tocopherol acetate (source of vitamin E), L-ascorbyl-2-polyphosphate (source of vitamin C), biotin, D-calcium pantothenate, vitamin A acetate, riboflavin supplement, niacin supplement, vitamin B12 supplement, pyridoxine hydrochloride (vitamin B6), thiamine mononitrate (vitamin B1), vitamin D3 supplement, folic acid], choline chloride, rosemary extract, preserved with mixed tocopherols and citric acid, L-arginine, trace minerals [zinc proteinate, manganese proteinate, zinc oxide, ferrous sulfate, manganous oxide, copper sulfate, sodium selenite, calcium iodate, copper proteinate], L-carnitine, fish oil, marigold extract (Tagetes erecta L.), taurine.
This food lists chicken by-product meal as its first ingredient, followed by barley, pea fibre, wheat gluten and corn protein meal. By-products are the leftovers which have been rejected for human use and can include heads, brains, beaks, hooves, etc. Wheat gluten and corn protein meal are not easily digestible, nor are they ingredients that dogs are naturally designed to eat and do not promote health and vitality.
Some Hill’s therapeutic formulas similarly use ingredients such as pork by-products, corn starch, potato protein and powdered cellulose.
At Tail Blazers, we take a different approach.
What We Look For at Tail Blazers
We don’t believe that a food needs to contain inexpensive fillers or animal by-products to provide appropriate nutrition.
Our Tail Blazers food philosophy avoids:
- Meat by-products and animal digest
- Brewer’s rice, wheat, corn, corn gluten meal, corn starch and corn protein meal
- Excessive starches
- Artificial colours, flavours and dyes
- Added sugars and dextrose
- Generic animal fats and certain inexpensive vegetable oils
- Carrageenan
- Chemical preservatives such as ethoxyquin and BHT
Instead, we look for identifiable animal proteins, quality fats, appropriate fibre sources, and ingredients that provide meaningful nutritional value.
What should you feed to prevent or support diabetes in dogs?
There isn’t one food that is right for every diabetic dog. Your dog’s ideal diet depends on their individual condition, weight, medications, blood glucose control, activity level and other health considerations.
At Tail Blazers, we look toward foods that are:
High in quality animal protein. Protein provides essential amino acids and helps support muscle mass.
Appropriate in fat and calories. Maintaining a healthy body weight is an important part of diabetes management.
Moderate to low in digestible carbohydrates. The amount and type of carbohydrate can affect post-meal blood glucose.
Rich in moisture. Canned, gently cooked and frozen raw foods can be useful options, particularly when increased moisture intake is desirable.
Made with named meats and ingredients. We prefer foods where you can identify the animal proteins, fats and other major ingredients.
Recommended Food Options
Ideally, feed a raw, unprocessed diet, which is easily digestible, provides more moisture, and keeps carbohydrates low. If raw feeding isn’t possible, gently cooked, meat-rich food is a good alternative. These are also recommended for prevention!
If those options aren’t available, consider air-dried foods such as Rawz, Raised Right, and Ziwi Peak, freeze-dried foods such as Primal and K9 Natural, or select high-meat canned foods such as Orijen or Rawz, depending on your dog’s individual needs. These foods contain species-appropriate ingredients that promote health and wellness.
Don’t Forget the Exercise
Nutrition is only one part of diabetes management.
Regular, consistent exercise can help support healthy body weight and glucose metabolism. However, consistency is especially important for diabetic dogs because significant changes in activity can affect insulin requirements and blood glucose.
In human’s it has been shown that a walk after a meal greatly aids in glucose metabolism. Going for a walk with your dog after you have both eaten is great for everyone!
Conclusion
Diabetes is a medical condition, and a healthful diet should be considered part of your dog’s overall treatment plan.
Dogs receiving insulin need regular monitoring, and changing their food can sometimes change their blood glucose and insulin requirements. Never change or discontinue insulin without veterinary guidance.
At Tail Blazers, our goal is to help you understand what’s in your pet’s food and give you options that align with a whole-food, ingredient-conscious approach.
