The term suspension is used to describe a moment when all four hooves of the horses are off the ground.

In trot, the horse moves in diagonal pair and the moment of suspension happens when the horse changes from one diagonal to the other. In canter, there is one suspension phase in each stride. When walking the horse always has at least one foot on the ground meaning that there is no moment of suspension.
