Eww! Gross! I look forward to feeding my dog nasty smelling meat. I did a little google research and this is what I came up with:
So how can something so disgusting, be so good? These same gastric juices and enzymes not only aid the animal in digestion, but also aid the dog in digesting and efficiently utilizing his food. The amino acids are necessary for muscular development and, the other gastric juices, we believe, are the best cleaner for their teeth! Finally, because of it’s rubbery texture, serving it in large chunks also aids the canine in strengthening it’s jaw muscles and has an added benefit as a form of canine dental floss.
