Dehydrated and Freeze-Dried dog food is a great alternative to a raw food diet. Dehydrating and Freeze-drying dog food is the process of removing the moisture and water while at the same time locking in the nutrients and goodness. Packed high in protein, low in carbohydrates - the process of dehydrating or freeze-drying dog food negates the need to add glycerin or extra fillers to preserve the food. Use as a meal replacer, meal-topper or treats.
