Well, I made TWO of these as soon as I read the post the other day, LOL...my dh travels a lot and seems to somehow lose socks in his travels, so I always save the ONE he brings back.....I always think the other one will turn up stuffed in his bag or who knows where? So I've got quite a collection~ I've gone thru two sets of the toy now....the first ones I made, I put the squeaker in, but Madison chewed thru the sock and destroyred both squeakers.....the second set, I put the top on the water bottle, didn't use a squeaker, but I put some of their hard kibble into the bottle (this also prevented the kibble from falling out of the bottle, which I think might be why he really tore up the "toy"...he could smell the kibble. But with the top on the bottle, it just makes noise. Then I put the wadded up empty treat bag on top and knotted the sock....I can't believe how MUCH they LOVE these! And it's so funny to see them just flipping them around! I also did one of them with a knot at the top and bottom (just so they have something to fight over

). Thanks for such a great idea!!! The boys thank you too
