(2-Pack) Chicken Glazed Collagen Tidbits

My dog loved these in the past, always having one around to chew on. They last awhile.Recent bag has less of the center part and more if the crumbling outer part. She gets that off easily and has thrown it back up every single time!! Idk what that outer layer is, but it’s different than before and I will miss having her constant chew around for a few safe sessions, through the day. Won’t buy again. Too expensive to throw it right up. Very disappointed
