RWD Dogsled

 Rear wheel drive (geared and covered) dogsled.

Forget the puppy snow goggles and the wind chill factor. You and your puppies can go out for a trot in comfort. This dogsled is covered in temperature-tolerant plastic, supported by attached flexible tubing. Your pooches are harnessed to a lightweight frame *behind* you on a paw-friendly treadmill. No more paws sinking into the snow. They run towards you (from behind). The treadmill is geared to a pair of lightweight tractor tread belts – one on each side. No need to train your pups how to turn – steering is done entirely by the ‘driver’ pivoting the sled runners. The sled is hinged to the treadmill/wheel frame to allow vertical movement, but no horizontal. Manually adjustable gears (via lever and cable) help out with the additional weight when going up hill, allow you to attain higher speeds than that of your pups on good level surfaces, and no need for braking while going down hills any more.

       Oh, you mean like a snow cat-erpillar?
—FarmerJohn, Jan 26 2003
   

       No, a sled is a vehicle mounted on runners, instead of the other way around.
—FarmerJohn, Jan 26 2003
   

       Yes [FJ] - a very comfortable caterpillar to use in extreme conditions.
—Shz, Jan 26 2003
   

       Bring it here. NYC was down to single digits F the other day. For us, that's extreme. Teach me how to drive the thing, while you're at it, please.

       Be there in a few days [snarfy]. I’ll put it in high-gear.
—Shz, Jan 26 2003
   

       To drive: Stand on sled skis as you would normally do – ask your energetic companions to go/mush/(come in this case). Tilt skis with feet as you would normally ski and it will turn.

       Absolutely riotous, sheazy. +

       If you only have just one rather tubby Shih Tzu, rather than a team of lean, mean Huskies, how fast can one expect to go under optimum conditions ?
—8th of 7, Jan 28 2003
   

       [8th of 7] If your dog is that tubby, I suggest you leave the Shih Tzu skidoo in neutral, and let the wee beast run off its extra pounds while you're in the mountain supplies store buying, I dunno, whatever people who live in snowy places buy - extra pullovers, or mitten-compatible keyboards, or somesuch.

       8th’s ‘dog’ is actually a cat disguised as a dog. Surprised it can even power itself, never mind the sled.   

       Ouch! – May have bought myself an especially sharp fishbone for that comment. Let’s see if it slips below the radar.
