I have a crazy chomping fool of a dog. He cannot and will not stop. He cares nothing about toys or fetch or puzzles. He wants to crunch and crack and snap. Luckily, his love of destruction is limited to bones and animal-part chewing items!Before the discovery of these, his favorite was the beef tracheas. He still enjoys tracheas, Benebones and some other chews, but THESE giant cheek rolls are his absolute favorite. He never tires of these. He chews them every day, sometimes for hours at a time!I have never noticed that they give him diarrhea or other issues, and obviously he loves the taste because he eats them constantly. They are VERY hard and substantial. Every once in a while, you get one roll which is a bit more flimsy, but mainly these are really thick and take a while for him to really get through.These are huge. I never fail to be shocked at just how the heck he gets through one of these, let alone multiple rolls per week. It's impressive. If you have a dog that really gets into the chewing.... these maybe for you.They do NOT smell bad, nor do they have any weird residue or colors that transfer onto surfaces or fabrics. I recommend these and I personally think they are a good value because NOTHING else entrances my dog and keeps him busy like these.
