Dogs jump differently when they continue straight after a jump or when they have to turn. It’s called jumping with extension (going straight) or collection (turning). The big difference between the two is the take-off point and the landing, which varies depending on the dog and their jump height. When dogs jump with extension, they will take off and land much further from the actual jump than when they have to collect in order to turn. The higher the jump, the further before they will take off in order to reach the highest point of the jump arc when they are over the bar.
In this video you can see examples for both, in regular time and in slow motion.
