Your vet may recommend a special diet for your diabetic dogs, such as Hills MD, RD, ID, or CD, or Purina OM, HA, or DM. These diets provide slow-release energy and avoid spikes in blood glucose.
No one diet is ideal for all diabetic dogs. This should be selected on an individual basis, depending on whether the dog is over or underweight, or has other health conditions (such as kidney disease or lack of pancreatic enzymes).
For example, it’s important an overweight diabetic dog loses weight (in a safe way) which improves diabetes control. This needs a good quality, high fibre, low-calorie diet. Alternatively, a thin dog needs building up, which requires a calorie-dense, slow energy release food.
