Markets in everything

Sherry Shumaker has grooved to "Dancing Queen," "Wild Thing" and "Doo Wah Diddy" with her dancing partner Heidi -- a Doberman pinscher.

At a Woodbridge studio, Heidi has taken lessons in standing on her hind legs, walking backwards and spinning, all in time to music and in sync to Shumaker's dance steps.

Here is the rest, and no I didn't know that dogs could take swimming lessons (silly me), or that you could arrange for them to watch back episodes of Lassie on satellite TV.
