Protein is best known for supplying amino acids to build hair, skin, nails, muscles, tendons, ligaments, and cartilage. It also plays a main role in hormone production.
The protein in dog foods can be supplied by animal sources, plant sources or a combination of the two. High-quality animal-source proteins contain all of the essential amino acids dogs need, while a single plant-based protein might not contain adequate amounts of some essential amino acids.
Common animal-based protein sources used in pet food include chicken, lamb, fish, and beef.
Even though they are often fed plant-based diets, dogs are not herbivores. While dogs are technically considered to be omnivores—animals that eat both animal- and plant-based foods—they should be treated primarily as carnivores to better fulfill their specific nutritional requirements.
Dogs are members of the Canidae family. This family also includes the wolf, coyote, fox, and jackal. The ancestors and relatives of today's common dog hunted animals and ate them as a means of survival.
The body structure of domestic dogs is similar to that of their ancestors and relatives and is ideal for eating prey. Dogs have the enlarged carnassial teeth after which carnivores are named. Their gastrointestinal tract is simple and does not have the capacity to digest large amounts of plant products.
Animal-based proteins help dogs achieve optimal health.
IAMS research has shown that some dog-food products are best formulated using a combination of carbohydrate sources. All IAMS dog foods are formulated precisely to meet the nutritional needs of your dog in his life stage. Such a combination offers optimal digestibility and helps maintain energy levels.
Our dog foods contain a variety of carbohydrate ingredients:
Barley: IAMS uses ground whole-grain barley that's cooked at high temperatures and finely ground in our dry dog-food formulas as part of our patented carbohydrate blend.
Corn: IAMS uses high-quality corn kernels that have been finely ground to break up the outside covering of each kernel, and then cooked at high temperatures to increase digestibility.
Grain sorghum: Also called milo, it is cracked, finely ground, and cooked before it is added to our dry dog foods. It is another carbohydrate source in our patented carbohydrate blend.
Rice flour: Our foods contain small kernels of white rice that have been separated from the larger kernels of milled rice, ground, and cooked at high temperatures to optimize digestibility.
Wheat: This is another high-quality carbohydrate source. In our biscuits, the wheat is an excellent, palatable carbohydrate source and adds a firm texture to the biscuit during the baking process.
Highly digestible diets are an important factor in the well-being of your dog. They deliver more essential nutrients more efficiently, so there is less waste.
Innovative and patented research by IAMS scientists has found that when the complex-carbohydrate sources grain sorghum and barley are used in a dog's diet, their breakdown is enhanced at another level.
These carbohydrate sources are all highly digestible, meaning your dog's body will still metabolize a high percentage of each for energy. What's unique about these grains is that they break down slowly and evenly, providing a stable source of energy.
The slow, even breakdown of grain sorghum, corn, and barley results in moderate, stable blood glucose levels after a meal. By minimizing swings in blood glucose, diets containing such a blend supply sustained energy. IAMS holds a patent on using grain sorghum and barley in a blend for dogs.
