kim: when i had two dogs, they (understandably) amused themselves a lot better than peanut does. hence, i find i buy peanut more toys. one nice little gadget is the busy-buddy. it's shaped like a dumbbell, with holes in the ends where you put treats. put in a few appropriately-sized treats, and your canine is busy, waving and dropping the busy-buddy, trying to cajole the treats out of their container. i prefer this style over some other ones, because it's made of rubber, so it works well with hardwood floors.
i've even taught peanut that she must bring it over and hand it to me (not drop it on the floor at my feet) when she is ready for more.
peanut: fill 'er up again, please!
