text: Unlike horses, which have only one period during their galloping stride in which all four legs are off the ground at once (the period when they are all contracted beneath the body), Greyhounds and many other fast dogs have two periods of suspension during their fastest gallop: the contracted phase, like the horse, plus the extended phase, like the picture of the Greyhound on the side of the bus.
