If a rawhide was stuck it would have been mush in that amount of time. Digestion for dogs and humans starts in the mouth with saliva. If you put a piece of cracker on your tongue and don't chew it, you can feel your saliva breaking it down. Saliva does not break down a Greenie.

This is the primary reason I don't give my pups Greenies.I think every
body should read all they can about this & make their own decision about
it. Just too many chemicals involved in manufactoring this product & I
don't feel comfortable about giving them.
