Fiber is important to your dog's health, providing bulk to move food through his intestinal tract. Some types of fiber can be fermented (broken down by bacteria) in the intestinal tract. This process creates short-chain fatty acids (SCFA), which are a key energy source for the cells lining the intestinal tract.
Most people are aware of fiber and its role in their diet. The beneficial effects of higher fiber levels in humans influence the way many people think about their own food—and their pets’ food. As a result, some pet-food manufacturers began to think like human nutritionists and make high-fiber diets for dogs. But high-fiber diets and the shorter digestive tracts of dogs don't always mix well. High fiber levels in dogs can cause digestive problems and interfere with proper nutrient absorption. Unlike humans, dogs are carnivorous, meaning their nutritional needs are better satisfied with meat rather than with plant materials.
For more than 60 years, pet nutritionists at IAMS™ have been studying diets to better meet the special nutritional needs of dogs. IAMS research shows that the optimal crude-fiber level for healthy dogs ranges from 1.4 to 3.5%. At these levels, nutrient digestibility is maximized.
An important characteristic of fiber is its fermentability, or how well it can be broken down by the bacteria that normally reside in the dog's intestine. This breakdown of dietary fiber produces SCFAs that provide energy to the cells lining the intestines. Different types of fiber vary in fermentability.
Fiber sources used in pet foods include cellulose, which is poorly fermentable; beet pulp, which is moderately fermentable; and gums and pectin, which can be highly fermentable.
Research has shown that moderate levels of moderately fermentable fiber, such as beet pulp, provide the benefits of energy for the intestinal lining and bulk without the negative effects of excessive stool or gas.
High levels of poorly fermentable fiber are used in some weight-reduction pet foods to dilute the calories in a serving. IAMS research found that this is not a good practice because high fiber levels can decrease the digestibility of other nutrients in the food and, therefore, can reduce the nutritional quality of the diet. You might also see more poop piles in the yard because of the indigestible fiber.
The key thing to remember about dietary fiber is that your dog's needs are not the same as yours. A moderate level of moderately fermentable fiber, such as beet pulp, provides proven nutritional benefits for dogs. Diets containing high levels of poorly fermentable fiber to dilute calorie content do not provide these nutritional benefits.
All IAMS products, including IAMS™ ProActive Health™ Adult MiniChunks, are formulated with optimal levels of moderately fermentable fiber to promote a healthy intestinal tract and enhance the well-being of your dog.
Obesity in dogs is a more common problem than you might think. Between 25% and 40% of dogs are overweight, but often, owners don’t realize it until they take their dog to the veterinarian for another reason. Yet even vets can’t tell if a dog is obese by their weight alone. Ideal weight varies by breed, and quite widely within breeds.(Did you know, for instance, that Labrador retrievers, dachshunds and beagles areall prone to obesity?) In short, there’s no ideal healthy weight chart for all dogs!
The good news is that if your dog is overweight, there are a number of ways to help them reach a healthy weight. Don’t underestimate the power of daily walks and a weight management dog diet — IAMS™ Adult Healthy Weight can help return your dog to a healthy weight, providing a path to help keep them fit for life.

Can you feel individual ribs easily? Is your dog’s abdomen slightly tucked up whenviewed from the side? That’s a sign your dog is at their ideal weight.
If you can't feel the ribs easily, your dog has no waist and their abdomen drags,your pup is carrying extra weight. Your veterinarian can help you further evaluateyour dog’s condition and determine their ideal weight.
Dogs gain weight for the same reason people do: They eat more calories than theyuse. Today’s dogs share another problem with their human parents: lack of activity.Many pet parents work all day and are too tired to play with their dog afterward.
Dogs’ metabolisms might slow as they age or after they’re spayed or neutered,which means they require less food. Another common reason for weight gain isfrequently eating high-calorie treats. Sometimes more than one family member isfeeding the dog, and the dog sure isn’t telling!
Other factors that could contribute to canine obesity include:
If you suspect that your dog is overweight or obese, the !rst step is to set up anappointment with your veterinarian so they can evaluate their condition. Likewise,before beginning any weight loss program with your dog, make sure to discuss itwith your vet.
If your dog is overweight, it’s time to implement a weight-management regimen. Ifyou usually feed one large meal a day or keep food available at all times, try adifferent dog-feeding schedule by dividing the daily ration into several small meals— at least two meals a day. It takes energy to digest food, and dividing your dog’sdaily ration into separate feedings will help. If your dog leaves any food in theirbowl, pick it up 30 minutes after each meal.

Your goal is to help your dog be healthier, so select their food carefully. Payattention to the ratio of fat, !ber, protein, carbohydrates and special ingredients inyour dog’s weight-management food:
After your dog reaches their ideal weight, select a maintenance food to keep theirweight steady.

Losing weight isn’t easy. Changing habits is the key. Here are some ways you can
help keep your dog on track:
A total weight-management program can lead to successful weight loss inoverweight or obese dogs. Remember: Your support is essential to your dog’sweight-control success.
