What technique is used to ensure a dog maintains sternal recumbency?

The technique of using downward pressure on the dog's thorax is effective in ensuring a dog maintains sternal recumbency because it encourages the animal to position itself correctly on its sternum. This position, where the dog is lying on its chest with its limbs extended, is often necessary for proper breathing and comfort during examinations or procedures. By applying gentle yet firm downward pressure, the dog is guided into or kept in the sternal position, allowing for relaxation and a stable posture.

This approach is particularly important in clinical settings, as maintaining sternal recumbency can facilitate various medical procedures and examinations, ensuring the safety and well-being of the animal. Other methods may not provide the same level of control or encouragement for the dog to adopt this specific posture.
