Providing dogs with vitamins, minerals, and other nutritional components is important to their health and well-being. The best way to do so is by feeding a high-quality complete and balanced diet. Supplementing dog food often upsets the balance and may lead to a variety of health problems.
People supplement their dog's diet for different reasons. Some of these reasons might include:
It is important for concerned pet owners to realize that a quality dog food is carefully formulated to meet the caloric needs of the animal. In addition, the food provides the essential amino acids, fatty acids, vitamins, and minerals specific to the nutritional requirements of dogs. Quality foods are complete and balanced for a specific life stage or lifestyle. By adding table scraps or other supplements, the delicate nutrient balance can be disrupted.
The interaction between different minerals is very complex. Fortunately, this is an area of nutrition that has been the focus of extensive research throughout many years. Research has shown that not only are the individual levels of minerals in a diet important, but so is the proper balance. An excess of one mineral may affect the absorption of a second, and lead to a deficiency in that second mineral.
One common supplement is feeding additional meat. However, because meat contains 20 to 40 times more phosphorus than calcium, adding meat to a balanced diet will upset the calcium to phosphorus (or Ca:P) ratio, which is important for proper bone development and maintenance. This may prompt the animal's body to absorb calcium from the bones in order to reach the right balance. This is often the case in older animals that experience tooth loss due to the resorption of bone from the lower jaw. Ca:P ratio should range between 1.1 to 1.4 parts of calcium for each 1 part of phosphorus.
Excess amounts of calcium have been associated with several bone diseases affecting growing puppies. Owners of large-breed puppies in particular believe that their puppies require extra calcium for proper development of large bones. Adding yogurt, cottage cheese, or calcium tablets to the pup's diet will only upset the body's delicate mineral balance. Remember that large-breed puppies will consume more food and receive the calcium their bodies need by eating the recommended portions. The best way to support a normal growth rate is to feed growing dogs adequate—but not excessive—amounts of a balanced diet, using a portion-controlled regimen.
The Association of American Feed Control Officials (AAFCO) regulates the pet food industry and has established certain nutritional requirements for dogs and cats. These requirements are published annually in the AAFCO Manual. Only pet foods that have met the strict testing criteria established by AAFCO can carry the 'complete and balanced' statement on the label.
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.
