Wheel dogs occupy the position immediately in front of the sled, making them crucial to the team’s overall performance. These dogs bear the most direct physical load, especially when starting a heavy sled from a standstill or pulling uphill. They must remain calm and steady despite having the sled moving closely behind them.
Strong, powerful dogs with a solid build are typically chosen for the wheel position. During turns, wheel dogs help pivot the sled by pulling it through the curve, preventing it from swinging wide or tipping. In sled dog racing, experienced wheel dogs can make the difference between a smooth run and a chaotic one.
Wheel dogs need a calm temperament since the sled, brake, and snow hook are all within close proximity. Nervous or easily startled dogs do not perform well in this role. Many mushers consider the wheel position second in importance only to the lead position, and they invest significant time selecting and training dogs suited for this demanding spot on the gangline.
