Now you can take your dog for a walk without ever leaving the house.

Get a look at the Doggy Health Run Pet Owner Exercise Treadmill, a $2,000 contraption in which Fido can run on a treadmill that's powered by a bicycle pedaled by a human. The faster you pedal, the faster your pooch has to move to keep up.

The bike and treadmill can be placed side-by-side or facing each other, providing the ultimate motivation for dropping those excess pounds.

The bike weighs 35 pounds, while the treadmill is 43 pounds, meaning getting them into your house won't wear you out so much you won't be able to use them once you've got them all set up.

Then, of course, there's the matter of that aforementioned $2,000 price tag. That sure seems like a lot of money, considering you can walk your dog outside for free.
