In which situation would sternal recumbency be the preferred method of restraint for a dog?

Sternal recumbency, where the dog is lying on its chest with the legs extended, allows for greater control over the animal during various veterinary procedures. This position not only provides physical stability but also allows the veterinary technician to effectively monitor the dog's heart rate, respiratory rate, and overall demeanor while still providing adequate access to various parts of the body.

When heightened control is needed, sternal recumbency enables the handler to keep the dog calm and secure, reducing the likelihood of sudden movements that could lead to injury for both the animal and the personnel involved. This method is particularly useful for procedures that may cause stress or discomfort, as it allows the technician to maintain a firm grip while minimizing the chance of the dog struggling or attempting to escape.

Other scenarios provided in the choices also involve specific situations where restraint might be required, but they do not necessarily emphasize the need for enhanced control in the way sternal recumbency does.
