Introduction
Have you ever been in the pet food aisle and looked at the extensive list of ingredients on a bag of pet food and felt a little overwhelmed? Knowing what these ingredients are is the most important thing you can do to pick the greatest food for your pet’s health.
The Goal of Formulation: What “Complete and Balanced” Really Means
You might encounter the phrase “complete and balanced” on packs of pet food a lot. The Association of American Feed Control Officials (AAFCO) establishes the nutritional guidelines for pet food in the United States.
A food that is branded “complete and balanced” has all the nutrients it needs in the right amounts. This means that the food can be the only thing that gives a pet nutrients for a certain stage of life.

- Whole Meats: Chicken, Beef, Lamb, or Fish.
