SOJOS ORIGINAL, introduced in 1985, comes in one formula for dogs and one for cats. It contains healthy whole grains, ground nuts, sea vegetables, and herbs. SOJOS GRAIN-FREE consists of healthy dried fruits and veggies, herbs, and ground nuts. Both SOJOS ORIGINAL and SOJOS GRAIN-FREE are intended to be mixed with your own source of raw meat. SOJOS COMPLETE is our newest product. This grain-free food comes in two varieties with either freeze-dried raw turkey, or freeze-dried raw beef in the bag for added convenience.
