Harness. Please do not use your regular walking harness. Mushing harnesses are designed to have dogs pull and their padding and manufacturing is different that your regular dog harness for walking. Best is to have a custom harness made to your dogs specific measurements.
Tugline. The tugline is the line that connects your dog to the scooter. Please have a bungee in addition (most bought tuglines have bungees integrated). The bungee is a shock absorber and limits injury when the dogs intially "takes off to run". You want to avoid a strong jerk.
