Pet owners are starting to be more aware about what they are feeding to their beloved animal. They rarely actually know what they are getting and just buy the most expensive food they can find. Most dog foods contain fillers like grains or starches with little meat, but a dogs digestive system is really made for eating meat as they are carnivores. There are many benefits to feeding grain free dog food. The main benefit is that their diet will mimic their natural ancestral diet. The food will digest easily and result in a longer lasting functional digestive system.
