16、may be fitted with a harness and collar, just so they get used to wearing them. As they get older, a small object may be attached to the harness to practice pulling weight.

24、s to the sled, and a tug line rigs the dogs harnesses to the tow line. The dogs collars are attached to the tow line by the neck line.
