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.
If you see signs of aging in your dog, don't wait to feed him the proper diet. Feeding a high-quality, premium food throughout your dog's life is the best way to help him age gracefully. When your dog reaches his mature years, choose a food like IAMS™ ProActive Health™ Mature Adult for nutrition suited to this stage of life. 'Good nutrition starts early,' says Dr. Michael Hayek, an IAMS research nutritionist who specializes in geriatric nutrition. 'It should be viewed as proactive health care because it may be a deterrent to aging later on.'
