For the Rookie You have 2 or 3 dogs and you're wondering what you need for lines? If you want to run 2 dogs' side by side using a sled, a light arctic shock bungee, 2 tug ropes and a leader neckline is all you need. If you want to run one dog in front of the other on a sled, a light duty arctic shock bungee, a 2-dog team section-polyethylene or cable filled polyethylene-and 1 tug rope that comes off of the front of the 2-dog section will do the job. If you want to run 3 dogs, the previous setup applies, the only change would be if you want 2 of the dogs to run in front, then you would need a 2nd tug rope and a leader neckline. The leader neckline attaches to each of the lead dog's collar ring; this keeps them both going in the same direction. Are you wondering how to hook up to a bicycle or scooter? The towline on the SKIJOR EQUIPMENT page works great for 1 or 2 dogs. All you need for 1 dog is the towline, if you want to run 2 dogs at the same time be sure to add an extra tug rope and a leader neckline. Safety Tip: Use something to guard the rope from getting wound up in the front tire so as not to stop short. Wheel sections are 9 feet and typically set up as the first section in front of the sled to get the dogs further away from it, Team sections are set up after the wheel section. Wheel sections are not an absolute necessity it comes down to personnel preference. 8-foot versus 7-foot team sections are again a personnel preference.
