100% Bison Liver (and nothing else!) Our freeze-dried bison liver is one of our most nutrient dense treats; they are extremely rich in: copper, taurine, and vitamins A, B2, and B12. Professional Trainers Recommend that, while training, you use 'high value' treats that are smaller in size to save money as you will be using a lot of treats; you don't need a big treat to motivate a dog, you just need something they go crazy for.  Content of the 7.5 oz. bag equals about 2 lbs of USDA-inspected raw meat before freeze-drying. All products are made in the USA, made without gluten or grain, & without additives.
