My dog absolutely loves these treats. This brand is by far the cheapest I have found and they are identical to the more expensive ones. I suggest picking up the packages by weight as as they are a much better value. I see some other reviewers complaining they didn't last long enough so you need to be aware that Esophagus treats(of any brand) are not long lasting chews. Think of them as more of a really good treat that will hold their full attention for several minute while they make great progress on it. My 25lbs dog took about 20 minutes on his first one and has that down to about 5 minutes now that he knows exactly what to do. He gets super excited each and every time he is offered one and he is a dog that will start to refuse most treats after he has had them awhile because he wants something new.
