What are the best high-fiber dog foods? Here’s what the reviews say

Walk down the food aisle of any pet store, and it’s enough to make your head spin. There are so many choices, it’s hard to know which food is best for your dog. When looking at ingredients, many pet owners don’t consider fiber, but it has important health benefits. High-fiber dog food typically has at least 6% fiber and ingredients that may include a selection of fruit and vegetables in addition to whole grains, brown rice, and oatmeal.

According to veterinarian Shawn Messonnier in an Animal Wellness magazine article, fiber encourages normal bowel movements, helps prevent overeating and obesity, and can also improve blood sugar control and stabilize a dog’s cholesterol levels. The best high-fiber dog food will also be high in protein and include vitamin-rich ingredients, providing your dog with a well-balanced, healthy diet.

According to veterinary experts at Tufts University Cummings School of Veterinary Medicine, the amount of fiber in different brands of dog food varies dramatically from one to another. Diets marketed for weight control are more likely to be relatively high in fiber. Keep in mind that while some dogs can tolerate different types and amounts of fiber, for others it may take some trial and error to find a diet that produces the ideal stool quality. If your dog tends to have diarrhea, suffers from constipation, or has diabetes or high blood fats, you should consult with a veterinary nutritionist for guidance on the best diet for him, Tufts University experts say.

Feed your pet the best possible diet

When choosing a diet, remember that dogs are individuals and their dietary needs will depend on their age, health, and personal preferences. If your dog tends to have diarrhea or suffer from constipation or has diabetes or high blood fats, you should consult with a veterinary nutritionist for advice on the best diet for your pup, according to Tufts University experts. If you’re planning to change your dog to a high-fiber diet, do your research, choose the food you think would work best for your dog, and then get your vet’s input. And when you’re finally ready to make the change, it needs to be done slowly by mixing the new food with the old to give your dog’s system a chance to adjust to the new diet.
