What Glycobalance is designed to do

A diabetic dog needs steady blood sugar, steady weight and the same food at the same times every day. Royal Canin says the dry formula has about 53 percent less starch than its Size Health Nutrition Medium Adult food, and the Chewy listing puts the figure at 49 percent for the version it sells, so check the label for your bag. It uses fiber sources such as pea fiber, beet pulp and psyllium husk to slow how fast sugars enter the blood. The protein is at least 35 percent to help keep muscle, and the fat is moderate to help keep weight in check.

Ingredients and numbers

On Royal Canin’s page the first ingredients of the dry formula are chicken by-product meal, barley, pea fiber, wheat gluten, corn protein meal and chicken fat. It lists starch capped at about 22 percent, sugars at 2 percent and crude fiber at about 9.8 percent. By-product meal is a standard pet food ingredient, but if you prefer foods made with named whole meats, mention that to your vet. Formulas are updated from time to time, so read your current bag.

Who it is for

  • Adult dogs diagnosed with diabetes mellitus by a vet
  • Dogs that need weight and glucose control together
  • Owners who want a prescription diet to use with insulin as directed by their vet

It is not meant for healthy dogs, puppies or dogs with certain other conditions, so do not switch a diabetic dog’s food without veterinary advice. Food changes can change insulin needs.

Feeding tips for diabetic dogs

  • Feed the same amount at the same times each day, usually matched to insulin injections as your vet directs.
  • Avoid sugary treats, table scraps and extra snacks unless your vet approves.
  • Weigh your dog regularly and keep notes on appetite, thirst and urination.
  • Mixing the dry and wet versions can add variety, but ask your vet how to adjust portions.

Pros and cons

Pros: Specifically designed for diabetic dogs, high protein, controlled starch, widely available through vets and online pharmacies.

Cons: It needs a prescription, costs more than regular kibble, and contains grains and by-product meal. Some dogs may dislike it.

Other options to discuss

If a dog also has kidney or digestive issues, the right diet can be different. You can read about kidney-friendly choices in our guide to Royal Canin Renal and treats for dogs with kidney disease.

Bottom line

Glycobalance is a reasonable, vet-backed choice for managing a diabetic dog’s diet. The most important thing is consistency and working closely with your vet on insulin and monitoring.

This review is general information, not veterinary advice. Diabetes needs veterinary care. Never change insulin or diet without talking to your vet.
