I first bought yipyaps as they are nearly protein free, and my dog was on a low protein diet for liver failure.  But it turned out that all 5 dogs love these yipyaps!  They're cute little crunchy treats, kinda like the old Pez candies but shaped like little bones.  Now I keep a tin in my purse for treats at the vet's office or wherever.  It's great to have a purse/pocket sized treat that never rubs off on your hands with stinky greasy crumbs, like other products.
