These things taste good, and are full of good organs/nutrients like bone, cartilage, ligaments, tendons, synovial fluid, nerve tissue, collagen, elastin, calcium, phosphate, glycosaminoglycans, hyaluronic acid. I cook them in the air fryer for 30 mins, and they go nice, and crunchy. I'm also eating dried tendon dog treats as tendons are important for muscle relaxation, and contraction. Dried tendons are on ebay or at pet shops. They have to be cooked for a while to go soft enough to eat. These foods are good for any neck/joint/bone/cartilage/muscle problems.
