My dog loved this as a pup (and still does), however it does not last long at all. Thinking I'd get our girl a treat that would keep her busy for awhile, I was a little surprised that it takes her less than 20 minutes to devour. As a pup, they kept her occupied for days but now as an adult, I don't think they are worth the money. As far as I know, these particular chews are not available in different sizes, which would probably help our situation if they were. Also, the "granola" tends to flake off and gets ground into our rug which is slightly annoying.
