Dog contraption. What do YOU think?

[urbpan]

Someone sent me a link to this site, which appears to be selling a variety of wheeled contraptions that you can attach dogs to. I'm all for making dogs earn their keep--if you're going to be feeding these things and picking up their feces, they ought to do something useful, too. I like the scooter (click the HOW IT WORKS link) but the person who sent me the link emphasized the 'trike,' which I don't actually see anywhere. But as far as the scooter/dog idea goes, the big variable is what if the dog decides to bolt after a squirrel/other dog/motorcycle/whatever triggers your dog to act like an idiot? Perhaps it's for people who don't have dogs that do such asinine things. What do you think?
