It’s important to remember that dogs just like humans, vary in their dietary needs over the course of their lives. Dogs are not strict carnivores so having a healthy amount of grains, fruits and vegetables can be a great source of essential vitamins, grains, and fruits. The primary thing you should look for is to see if the product bag states its formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles. The AAFCO had strict requirements to make sure that a product is in fact complete and balanced for dogs.
