So we got this rawhide for Casey about a month ago. He didn't want much to do with it forever when we first got it, he carried it around but wouldn't chew it. Well today he had been chewing it all afternoon, all over the house, wherever he goes. I just noticed the chewing that has been going on next to me for the past hours had stopped. i looked over and Casey dog was passed out with his rawhide still in his mouth.  Silly dog. Mommy took it out of his mouth for him and he didn't even move, it wore him out, now he is sleeping.
