Dogs lie down and stand up so many times a day, but that simple movement can be adapted to efficiently work many areas of the body.
Picture a dog lying down from a sitting position. First, they move the rear part of their body down to the ground and then they use their forelimbs to walk the front of the body down towards the floor. There are not many muscle groups engaged during this movement…basically, the shoulders are working as they move down and in pushing themselves back up into a stand.
Now imagine the action of a “folding down”. This is when the dog lies down in the “sphinx” position with the knees and feet track forward while the hips are tucked in close to the body.
The dog starts from a standing position with the rear feet a natural distance from the front feet. The back is flat with no arch (if that is the dog’s natural topline) and the head is in a neutral position. As the dog moves into the down position, there is no movement of the front and rear feet. When moving back into the standing position, all four feet stay in place. No movement. Check out this video of a folding down in slow motion…
