Hi all,

Great idea to freeze liquids inside the toy--a Kongsicle! I guess first you have to plug up the smaller hole and freeze it upright. I'll have to try that.

I've heard of some dogs being such aggressive chewers that they can actually destroy a Kong (which would definitely keep them busy!), so the black ones are made of super-heavy-duty rubber. Tinier Kongs are good for small dogs and dogs that don't enjoy the challenge so much.

A Google search on "kong stuffing" brought up tons of sites. I'll have to get my butt into the kitchen and try some new things!
