A healthy diet is just as important for your pet as for you and your family, and it’s a proven fact that dogs who eat less, live longer. 1 On the flip side, obese dogs are at risk of life-threatening illnesses, such as heart disease, type 2 diabetes, high blood pressure, kidney disease, and cancer. Many commercially produced pet foods are high in fat, salt, and sugar and contain low-quality meat. They are often so over-processed that most of the nutrients have been removed. Freeze-dried dog food is the closest thing to providing your dog with a raw diet, and it retains all of the vitamins, nutrients, and flavors of the original raw food.
