Hi everybody. Here's a pic of Taco's favorite toy. It's called an I.Q. Cube. It comes with 4 little stuffed shapes that have squeaky's in them and you put them in the inside of the cube and he has to stick his head in the cube and take them out. He loves it. As long as I keep putting them back in there, he plays with it forever. I picked it up at Petco. And, its machine washable. Just thought I'd share incase somebody else wanted to try one. I bet a crafty person could even make one. Maybe even smaller for a smaller chi.
