The equine canter is a 3 time beat with a moment of suspension after the sequence. The canter lead is determined by the forleg which moves last and reaches furthers forward. when a horse is on the left rein, if he has the correct lead, the left leg should lead, and vice versa.
In this Left rein canter, the Right (offside) hind initiates the movement, the left (near) hind and right (offside) fore leg move together as a diagonal and then the left (near) foreleg moves. There is a moment of suspension and the sequence is repeated.
At 20 seconds, the pony carries out a downward transition to trot and you can see the contralateral (opposite) front (fore) legs and back (hind) legs move together as diagonals with a moment of suspension between them.
