@punkstardogsspam: As crufts 2023 is coming up, I want to remind everyone that there is no such thing as a 'straight back' german shepherd. The angulation when a german shepherd dog is in a 3 point stack is called the croup, NOT the back. Which has been bred for a steeper angulation to aid in herding using the flying trot german shepherd, which is a trotting gait the german shepherd dog preforms in order to cover more ground quickly and without exhaust as 'boundary herder'. Here is my poodle showing how a 3 point stack can alter the way the dog's rear is angulated.
