it's been many years since i had sled dogs but i sure remember the fun we had! i had 2 siberian huskies, a friend of mine had 3. sometimes we raced, other times we hooked all 5 dogs to the same sled and took turns.
i don't know if one mal would be able to pull you on a sled but much would depend on the size/strength of the dog, your size and the surface you are on. my 2 sibes had no trouble pulling me all day long but i'm a lightweight and i always took them out on firmly packed snow.
this is how we started...
once they were used to pulling a small wagon, we graduated to regular racing harnesses and they were hitched, one at a time, to a small car tire. we gradually increased the size/weight of the tire until they were pulling a fairly heavy one.
there are lots of good books for beginning mushers. can't think of any off the top of my head but i'm sure google could help you out. it's important to take it very slowly because pulling weight with a harness is much different than dragging you down the street by collar/leash.
this is me with all 5 dogs. i didn't really have big hair, we were going at a pretty good clip when my friend took this picture so my hair was blowing in the wind.
the red sibe at the right of the pic is my female, in the swing position. my male is the one in the wheel position in the back. most of the time, my female was our lead dog. she was sharp as a tack and learned commands very quickly. my male was always a wheel dog because he was so powerful.
