10 Best Foods for Dogs With Diabetes 2025: Vet-Approved

This content was reviewed and fact-checked by veterinarian Dr. Aukse Caraite, DVM.

Imagine carefully managing your dog’s insulin, only to realize their food is sabotaging your efforts. Diabetes in dogs isn’t just about medication, but every bite they take. The wrong diet can send their blood sugar soaring, leading to energy crashes, weight gain, or even life-threatening complications. But here’s the catch: many “healthy” dog foods contain hidden sugars, high-glycemic carbs, and fillers that can wreak havoc on diabetic pups. So, how do you separate the truly beneficial options from the marketing hype? In this guide, we’ll break down the best diabetic dog foods, what ingredients to embrace (and avoid), and how to ensure your dog’s diet supports stable blood sugar, without sacrificing taste or nutrition.

What is Diabetes in Dogs?

Diabetes in dogs is a chronic condition where the body cannot properly use glucose due to insufficient insulin or the body’s inability to respond to it, leading to high blood sugar (hyperglycemia). Insulin is vital for moving glucose into cells for energy. Common symptoms include increased thirst (polydipsia), frequent urination (polyuria), increased appetite (polyphagia), weight loss, lethargy, cloudy eyes (cataracts), and recurring infections. In severe cases, it can lead to life-threatening complications such as diabetic ketoacidosis (DKA)—a buildup of blood acids due to lack of insulin—and organ damage affecting the kidneys, eyes, heart, blood vessels, and nerves.

The Best Food for Diabetic Dogs According to Science

According to the latest research studies, the best food for dogs with diabetes has the following characteristics:

• High-fiber diets improve glycemic control: A study involving 10 dogs with insulin-dependent diabetes mellitus demonstrated that switching to a high-fiber diet significantly lowered mean 24-hour and postprandial plasma glucose concentrations. Additionally, there were notable reductions in plasma fructosamine, glycated hemoglobin, free glycerol, and cholesterol levels, alongside improvements in activity and demeanor.
• High-fat diets induce metabolic alterations: Research showed that feeding dogs a high-fat diet for 17 weeks led to increased body and insulin resistance, complicating diabetes management.
• Carbohydrates and their effects on diabetic dogs: A study concluded that dog diets with higher carbohydrate content led to more pronounced increases in blood glucose and insulin levels. This suggests that selecting commercial dog foods with lower carbohydrate content may help manage blood sugar levels, which is particularly important for dogs with diabetes.

Other key characteristics include low glycemic index ingredients, low fat, and fortified with antioxidants and omega-3s.

Safe Ingredients For Diabetic Dogs

You MUST work with your vet before changing your dog’s diet, especially if they have a condition like diabetes. Alternatively, you can get personalized nutritional advice from an online registered vet nutritionist through platforms like Vetster anytime, anywhere. You can also chat with an online vet and ask them questions about your dog’s nutritional needs. Additionally, at-home dog gut health tests can analyze your dog’s microbiome, offering insights into which nutrients their diet should include. Similarly, at-home dog allergy testing kits can identify ingredients that may not be suitable for your dog, enabling you to choose the right diet and care plan to support optimal digestion and nutrition.

Feeding Tips for Dogs with Diabetes

Managing your dog’s diabetes effectively involves careful attention to their diet and feeding habits. Here are some essential tips to help maintain stable blood sugar levels and overall health:

1. Maintain a consistent feeding schedule: Establish a regular feeding routine by providing the same amount of food at the same times each day. This consistency helps prevent fluctuations in blood glucose levels. Traditionally, the dog’s daily food intake should be divided into two meals, approximately 12 hours apart.

2. Practice portion control: Monitor your dog’s caloric intake to maintain an ideal body weight. Overweight dogs may require weight loss to improve insulin sensitivity, while underweight dogs might need a diet higher in calories. Use a measuring cup to ensure accurate portion sizes and avoid overfeeding

3. Choose appropriate treats: Select treats low in carbohydrates and calories. High-fiber vegetables, such as baby carrots, can be suitable options. Ensure that treats do not exceed 10% of your dog’s daily caloric intake. We recommend Marcy’s Pet Kitchen-Diabetic Dog Treats on Amazon.

4. Avoid sugary and high-carbohydrate foods: Steer clear of foods containing refined sugars, such as semi-moist dog foods, which often have high sugar content. High-carb diets can lead to elevated blood glucose levels, complicating diabetes management.

5. Monitor blood sugar levels: Keep track of your dog’s weight, food intake, and blood glucose levels. Regular check-ups with your veterinarian are crucial to adjust dietary plans and insulin dosages as needed.
