Most commercial pet foods contain only small amounts of bioavailable nutrients, even those that are diet/breed specific. Most commercial dried foods have been through heating processes and so lose nutrients and vital essential fatty acids. They also contain lots of carbohydrates such as potatoes, peas, wheat, oats or rice which are high in starch and sugars, akin to refined foods that we eat. Feeding a fresh diet to your dog will support better health in your dog. Although labelled as a supplement, Proflax is a food additive that will support all aspects of your dogs health.
