AbizooSilicone Plug for Toppl Dog Toy,Ocean Theme Shark Shell Shape Stopper for Toppl L/XL Works Great Holds in Liquids,for Better Frozen Dog Treats

These plugs work perfectly for the Westpaws Toppl Large and XL. Easy to use, easy to clean, just remember to always remove plug before giving the Toppl to your pet. Plug also fit the bottom of the Busy Buddy Squirrel medium and large.*If you have a SMALL Toppl and want to plug it, I found that a rubber tipped wine stopper works. Cork gets brittle in the freezer and broke off when I tried removing it. A section of carrot will do for semi solid foods, but leaked when I tried it with liquid.

Use to use chicken hearts to stuff the hole but this works so much better no leaking

These stoppers are perfect. They prevented any liquids leaking out of the toppl's and they are incredibly cute.

These are so cute! They really stop everything from coming out of here.PRO TIP: take the stopper out before giving to your dog or they may eat it like mine, lol. Lesson learned!

These are excellent. I’ve tried several other stoppers and these are the first to not drip any liquid out. Plus they are dishwasher safe. Definitely recommend.

The media could not be loaded.  LOVE THIS PRODUCT! It keeps every inside of the toppl and is super easy to wash!

It’s been a pain to fill toppls and have to figure out how to avoid leaking messes. These worked great in the L and XL toppls. Only wish they offered for the S size. Happy enough to buy a second set!

These were bigger than I thought, but they fit the L and XL toppl perfectly! Great for stopping the liquid when freezing goodies in the toppl. Remember to remove the stopper before you give it to your dog.
