haha...Ya I leave Teddy a kong filled with peanut butter about everyother day and it keeps him busy for a while when im gone and he seems to love it... I heard you can also put the kong in the freezer with the peanut butter and that makes a great treat as well...Ive also heard some people put little treats inside and some dogs will sit there for hours trying to get them out of the kong, but my dog just gives up after a few minutes so I stick with the peanut butter...
