Proteins are a category of the most essential macronutrients that all pets need in their diet in order to survive. Proteins are responsible for building and repairing muscle tissue, maintaining a healthy skin and a healthy coat as well as helping with hormone regulation. Proteins consists of amino acids. Some amino acids are produced by our pets. However, some others called essential amino acids, need to be supplied to your pets through their food.
There are differences in the types of amino acids and the quantities each animal protein has and each pet digests each animal protein differently. Having 2 sources of animal protein ensures that your pet will get the highest amount of essential amino acids needed and help him or her avoid developing a hyper sensibility to a specific protein source. This results in a completer and more hypoallergenic pet food.
