Plain-English summary
A group of 12 dogs with stabilized diabetes were tested on different diets to see if a high-fiber, moderate-carbohydrate diet would help control their blood sugar better than a commercial diet with moderate fiber and low carbohydrates. The results showed that there was no significant difference in insulin needs or blood sugar control between the diets. However, the dogs on the high-fiber diet lost weight, while those on the other diets maintained their weight. Overall, the high-fiber diet didn't provide any benefits for these diabetic dogs and may not be suitable for those that are already thin.

Abstract
OBJECTIVES: To assess the influence of high-fibre, moderate-carbohydrate diets with two levels of dietary fat, compared with a commercial diet with moderate-fibre, low-carbohydrate and higher fat, on insulin requirement, glycaemic control and lipid profile of dogs with stabilised diabetes. METHODS: Twelve dogs with spontaneous diabetes mellitus were studied. Glycaemic control was evaluated by plasma fructosamine, glycosylated haemoglobin and 48-hour serial blood glucose measurements. The insulin dosage required to maintain clinical stability was also determined. Lipid profiles comprised serial measurements of plasma cholesterol, triglyceride, free glycerol and free fatty acids. Data were analysed using analysis of variance. RESULTS: There were no significant differences in insulin requirement or glycaemic control among diets. Weight loss occurred when the dogs were fed the high-fibre, moderate-carbohydrate, moderate-fat diet (P<0.002), whereas weight was maintained with the other two diets. The high-fibre, moderate-carbohydrate, moderate-fat diet resulted in lower mean plasma cholesterol compared with either of the higher-fat diets (P< or =0.003), and lower mean plasma triglyceride (P=0.060), free fatty acid (P<0.001) and free glycerol (P=0.015) than the commercial diet. CLINICAL SIGNIFICANCE: For stable diabetic dogs, high-fibre, moderate-carbohydrate diets offered no significant advantage compared with a commercial diet with moderate fibre and low carbohydrate. Diets with high fibre, moderate carbohydrate and moderate fat should not be routinely recommended for dogs with thin body condition.
