Some of the sequences were harder than others. The jump tunnel jump got quite a few dogs running past the tunnel opening. As Le explained it there were four reasons for this:
- People got caught behind the wing of the jump, and in stepping around it pulled their dog to the right and away from the entry.
- People were behind their dog at the jump and the dog turned back towards them missing the entry.
- People turned too soon, dropping their left arm before the dog had committed to the entry.
- The tunnel curved to the left, away from where the dogs knew the reward was.
