the odd time I do, but mmy dogs dont much like them, they dont like the rubbery taste on the kongs, they love the water kong though(with a rope that you throw in water) it broke at Jordans(wolfsouls) when I there, so I pulled out the inside foam and gave it to the dogs as a regular kong, they seem to like it ok, it does not have the same taste and feel of the normal kongs.
