There are so many misconceptions about pet food ingredients. Dr. Anna Coffin will discuss common ingredient terms seen on pet food labels so that you can make an educated decision about what to feed your pet.
One important misconception is that pet food ingredients contain human grade products. Everything starts off as human grade food, but once the product leaves the USDA inspection facility, it is considered pet food. Nothing that goes into pet food is human grade.
Dogs are omnivores, which means that they derive their nutrition from animal and plant materials. Cats are obligate carnivores, which means that their nutritional needs are met by eating animal based proteins. Therefore, protein is the most important pet food ingredients within pet food. Because of the differences in dogs and cats, it is important to look at the label to see how much of the protein in the diet is animal vs. plant based. In cats, 30 to 40 percent of the diet should be made up of protein. In contrast, dog food should consist of 20 to 30 percent protein.
