Dog exercise toy:
the awsome empty milk jug

It's great for indoor exersize and all you need to do it get an empty milk jug and throw it down the hall. Then my dog goes running after it and he just keeps kicking the milk jug and running after it again and again. This is kind of noisy but extremely funny, and it lets your dog get lots of exersize and fun.
