John, if you have Malamutes, two is plenty to start with. And if you don’t have snow, that’s just fine too. Get yourself a tough mountain bike or even a BMX, loop an eight or ten-foot line around the centrepost above the front fork, attach two three-foot tuglines to the far end of that, and put a neckline between the two dogs’ collars, 10-12 inches long. And you are in business! This is how I train lead dogs in the summertime in Canada, so they know what I want them to do when the snow flies. Maybe even try it with just one dog at first, until you get some confidence. And never, ever try “bike-joring” with more than two dogs, it gets too dangerous.
