Ingredients: 100% beef lungs 
Package size: 1.5 oz. / 4.5 oz. / 9 oz.
Highlights:
- Our freeze-dried raw beef lungs are extremely rich in taurine and high in: vitamin B12, vitamin C, iron, and protein
- 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 will go crazy for
- Content of the 4.5 oz. bag equals about 1 lb. of raw meat before freeze-drying, sourced from USDA-inspected beef
