I could not say if these will work over the long haul as far as joint improvement because I just had the sample pack but I can say that the dogs seemed to enjoy them immensly.

Maybe a Chihuahua could make these bones last, but any dog with a mouthful of teeth will dispose of any size Bonie really quick. My dogs disappeared the 3-inch version in about 5 minutes. They love them, but it's an expensive treat, given its longevity.
