Dog Mushing Glossary
The complete guide to mushing terminology. From lead dog to snow hook, learn every term used in dog-powered sports.
B
Basket Sled
A traditional sled featuring an open framework basket mounted on two runners, used for carrying gear, supplies, or passengers, and the most common sled type in distance racing.
Bikejoring
A dog sport where one or two dogs pull a cyclist via a bungee line attached to the bike frame, combining mountain biking with the pulling drive of trained dogs on dirt trails and forest roads.
Booties
Lightweight protective fabric coverings worn on sled dogs' paws to prevent ice buildup between the toes, abrasion from rough trail surfaces, and cuts from sharp ice crystals during training and racing.
C
Canicross
The sport of cross-country running with a dog attached to the runner via a bungee line and waist belt, where the dog pulls from the front while the runner maintains pace behind over varied terrain.
Checkpoint
A designated stop along a race course where mushers must check in, rest their dog teams, and where veterinarians perform mandatory health examinations on every dog before the team is cleared to continue.
Come Haw
A mushing voice command that directs the lead dogs to make a complete 180-degree turn to the left, effectively reversing the entire team's direction of travel on the trail.
D
Dog Driver
Another term for a musher, commonly used in Scandinavia and parts of Europe, referring to the person who drives and manages a team of sled dogs during training or competition.
Dog Lot
The designated area where sled dogs are housed and cared for on a daily basis, typically featuring individual insulated dog houses, tethering posts or fenced enclosures, and organized spaces for feeding, watering, and exercising the dogs.
Dog Scootering
A dryland mushing sport where one or more dogs pull a rider standing on a specially designed kick scooter, offering an accessible and fun entry point into dog-powered sports on trails and dirt roads.
Dog Yard
The designated area where a musher's sled dogs are housed, fed, exercised, and trained on a daily basis, serving as the operational heart of a mushing kennel and the dogs' primary living space.
Drag Mat
A heavy rubber or carpet mat attached beneath the sled runners that the musher can step on to create friction against the snow surface, providing a gentle braking effect to help control the team's speed on descents and approaches.
Dropped Dog
A dog removed from a racing team at a checkpoint due to injury, illness, or fatigue, left in the care of race veterinarians and volunteers until it can be safely transported back to the kennel.
G
Gangline
The central rope or line running from the sled to the lead dogs that connects all dogs in a sled dog team, serving as the backbone of the rigging system to which tuglines and necklines attach for each dog position.
Gee & Haw
The two primary directional voice commands used in mushing: 'Gee' instructs the lead dog to turn right, while 'Haw' instructs the lead dog to turn left, forming the foundation of musher-to-dog communication on the trail.
H
H-Back Harness
A pulling harness with a horizontal strap connecting two parallel side straps across the dog's back, providing a shorter and gentler fit than an x-back harness, ideal for dogs with back sensitivities.
Handler
A person who assists a musher with daily dog care, training runs, feeding schedules, and race logistics, serving as essential support staff in sled dog kennel operations and at race checkpoints throughout the season.
Harness
A fitted garment worn by a pulling dog that distributes the force of pulling across the chest and shoulders rather than the neck, allowing the dog to work efficiently and comfortably during mushing activities.
L
Lead Dog
The dog or pair of dogs positioned at the very front of a sled dog team, responsible for following the musher's directional commands such as gee and haw, setting the pace, and guiding the rest of the team along the trail.
Line Out
A command or the act of holding the lead dogs forward to keep the gangline taut and the entire team lined out straight ahead while the musher prepares the sled, adjusts gear, or gets ready to depart.
M
Mid-Distance Race
A sled dog race covering 100 to 350 miles that requires a balance of speed and endurance, with teams navigating checkpoints and mandatory rest periods over several days.
Musher
A person who drives a sled dog team or participates in dog-powered sports, responsible for training, caring for, and guiding their dogs during races, expeditions, recreational runs, and everyday kennel operations.
P
Pedaling
The act of a musher pushing the sled forward by kicking off the ground with one foot while the other foot remains planted on the runner, helping the dogs maintain speed on flat or uphill terrain.
Point Dog
Another term for the lead dog — the dog running at the very front of a sled dog team, responsible for setting the pace, following the musher's directional commands, and guiding the rest of the team down the trail.
S
Skijoring
A winter sport in which a person on cross-country skis is pulled by one or more dogs attached via a bungee towline and hip belt, combining the techniques of skiing with the power of trained pulling dogs.
Sled Bag
The fabric compartment mounted on a dogsled frame used to carry mandatory gear, dog food, human supplies, and — when necessary during races — injured or fatigued dogs that need to be transported to the next checkpoint.
Snow Hook
A large, heavy metal hook attached to the sled by a rope, used to anchor the sled by driving it firmly into packed snow or ice so the musher can temporarily stop the team and step away from the sled safely.
Sprint Race
A short-distance sled dog race, typically 4 to 30 miles, where teams compete for the fastest time over one or more heats held across a single day or weekend.
Swing Dog
The dog or pair of dogs positioned directly behind the lead dogs, responsible for helping swing the rest of the team around turns and corners while maintaining the formation set by the leaders on the trail.
T
Team Dog
Any sled dog running in the middle of the team between the swing dogs and the wheel dogs, providing the bulk of the pulling power and maintaining a steady pace within the formation.
Toboggan Sled
A flat-bottomed sled that slides on a continuous surface rather than runners, providing excellent flotation in deep or soft snow and greater stability on uneven terrain.
Trail (Command)
A mushing right-of-way call shouted by a musher to request that the team ahead pull over and yield the trail, allowing the faster team to pass safely — similar to calling 'on your left' in cycling.
Tugline
A short line connecting a sled dog's harness to the central gangline, designed to transfer the dog's pulling force efficiently to the main line and ultimately propel the sled forward along the trail.
W
Wheel Dog
The dog or pair of dogs positioned closest to the sled, directly in front of it, responsible for providing strong pulling power, maintaining stability during turns, and helping steer the sled around corners on the trail.
Whoa
The standard mushing voice command used to instruct a sled dog team to stop or slow down, considered one of the most critical commands for maintaining safety and control during any sled dog run or race on the trail.
