A Note on Meat Byproducts

There has been a lot of controversy over the use of meat byproducts. This simply means that the food uses bone, stomach, brains, and other parts of animals in the food. Parts of animals that will put dogs at risk of health conditions, such as mad cow disease, are not permitted for use in pet food. Meat byproducts are actually a good source of protein. Instead of worrying over the source of the meat, it is more important to look at the percentage of protein and the additional nutrients in the food.

All dog foods should meet the minimum standards of at least 10% protein, 5.5% fat, and 2.5% crude fiber. This dog food contains significantly more of these vital ingredients for the ultimate nutrition for your aging dog.
