These have been going strong in the YWD household for many years; they are robust and versatile - suitable for both dried food and also for the stuff-and-freeze thing.
Here's the official Busy Buddy blurb:

Every dog plays differently and, since not all toys are created equal, it’s always best to keep a close watch on your pup in case things get ruff. Supervised play will help toys last longer and most importantly keep your pal safe. No dog toy is truly indestructible, so always remove the toy from playtime if pieces begin to break off.
