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.
Low-cost food might be better for your wallet, but it can be a raw deal for your dog, because he may not get the nutrition he needs. Premium foods, such as IAMS™ ProActive Health™ Smart Puppy Original , make sense both nutritionally (because of consistent, high-quality ingredients) and economically because they provide:
The investment in a premium food might initially cost more per bag, but because these high-quality formulas are high in nutrient density, your dog may need less food, which can offset the higher cost per unit of weight. On a cost-per-feeding basis, look at how much you feed each day as opposed to how much the bag costs, because nutrient and energy density will generally be lower for a low-cost food compared with premium foods.
With budget-priced formulas, the emphasis is on production and ingredient costs. Two bags of the same least-cost formulated food can have different ingredients and/or levels of ingredients. Plus, those ingredients may vary significantly in digestibility. This means, simply, that you may need to feed more just to equal the nutrition offered by a smaller amount of a premium dog food formula.
High-quality, complete, and balanced premium dog foods such as the IAMS brands are specifically designed to provide your dog with a food that has:
To determine how much food to give your dog, check the daily feeding recommendations set by the pet food manufacturer and read the label. To calculate portion sizes, divide the total daily recommended amount by the number of times (usually two for adult dogs) you plan to feed your dog.
To tell if your dog is at a healthy weight, move your hands along his sides. If you can feel his ribs, he's about right. Or, look down at him when you're directly above him. You should be able to see a waistline.
If he's gaining or losing a lot of weight, slightly decrease or increase his daily intake and weigh him in another week. If you have specific concerns about your dog's weight, talk to your veterinarian. He or she can assess your dog's needs and make a feeding recommendation.
Once you've decided on a premium formula, you have another choice to make: dry or moist. And what about biscuits?
Premium dry dog food gives you the best value and convenience, while fortifying your dog with high-quality nutrition. Premium dry foods come in a number of bag sizes and formulas suited to size, life stage, and activity level. Dry food also helps keep teeth clean, and it stays fresh for a long time if you store it properly.
Wet foods from IAMS provide 100% complete nutrition. IAMS ProActive Health Puppy Biscuits make great treats and rewards and can add taste variety to your new dog's diet.
