If you join the siberian Husky club of GB, they have a forum, where members will advice you on training, and maybe you can get to meet up with some other husky owners to practice. Usually the dogs know when they have a working harness on and when they have their walking lead on, its all a matter of training, you need to train your dog to walk on lead like any other breed, it can be done, just because they are sibes does not mean that they automatically pull on lead, ALL dogs do this if not trained, the harnesses you use for pulling a sled/rig is usually an X back harness, this must fit correctly. As you are walkng your dog you can give commands, ie gee for right and haw for left, these are the common commands for working huskies, and most mushers use this terminology, there is also onby to pass other teams/dogs, what I would say though is one sibe is not IMO strong enough to pull an adult person and the sled/rig, it usually requires at least two dogs to do this, and that also includes the musher assisting uphill by scootering with one foot, obviousy it would be fantastic if two dogs could pull all this weight without assistance, but they would have to be amazingly fit to do so.
