Yappetizers lamb liver dog treat is rich in protein and vitamins which helps support optimal good health. Our lamb liver is slowly dehydrated over a long period of time. This slow process of dehydration perfectly preserves our liver without the use of additives or preservatives. Our dehydration process removes almost all of the moisture allowing our products to be naturally shelf stable for over 2 years. As with all of our products our lamb liver is human-grade and sourced from federally inspected plants. This lamb liver treat is hand-made in our very own CFIA (Canadian Food Inspection Agency) certified plant located in Richmond, BC Canada.
