Diabetes in Dogs

Nutrition for Dogs
with Diabetes

Healthy Food Choices

The best diet for your dog is the one that it will eat reliably and is suitable to maintain your dog at its optimum weight. Ask your vet for advice about the best diet for your diabetic dog.

Prescription Diets – These are specially formulated for the management of dogs with diabetes. Diets that contain higher fibre can be particularly useful for helping with weight loss and improving blood sugar control.

Non‐prescription Diets – Diabetes can be managed on a carefully controlled program using their normal diet. It is much easier to manage these plans if a food with complete nutrition is used but one should try to avoid diets with high fat content.

Water Consumption – Clean drinking water should be available at all times. A reduction in excessive water consumption is an indicator of successful management of diabetes.

Tips for a Healthy Diet

No matter which diet option you choose, these are the basics for diabetes control:

Consistently feed your dog the same amount of food at the same times each day to avoid unnecessary fluctuations in blood glucose.

Work with your vet to find the correct caloric value to help your dog achieve optimal weight.

Restrict fat in their diet to avoid additional complications.

Timing Meals and Treatments

Your veterinary team will advise you on properly feeding your dog. In general, meals should be timed so that the food in their body coincides with the peak action of the given insulin. This will minimise fluctuations in blood glucose concentrations and, thus, episodes of hyperglycaemia and hypoglycaemia.

For once-daily insulin injections:Give the first meal (two-thirds of the daily amount) prior to the morning Caninsulin® injection. This allows you to see that your dog is feeling well and eating normally before the insulin is given.

The second meal (the remainder of the daily amount) is usually given about 8-10 hours later.

For twice-daily insulin injections:

As a general rule, feed half of your dog’s total daily food right before or with each injection.

The first meal (half of the daily ration) is given just before the morning insulin injection. This allows you to see that the dog is feeling well and eating normally before the insulin is given.

The second meal (the remainder of the daily ration) is usually given about 10–12 hours later, prior to the second insulin injection.

For specific questions regarding type, volume, timing and frequency of feedings, please consult your vet.

Importance of an Ideal Body Weight

Achieving your dog’s ideal body weight is best for diabetes management. Underweight dogs should avoid high carbohydrates and fibre to best manage diabetes.

For overweight or obese dogs, the goal is controlled weight loss. Overweight dogs can have insulin resistance, which may lead to higher doses being required.

Weight loss should be gradual and should be no more than 5% of their bodyweight per week. Your vet is the best resource to calculate the ideal body weight and food requirements for your dog with diabetes.
