What does euthanasia involve?

Euthanasia involves the induction of death in a sick or injured animal, typically carried out to alleviate suffering when recovery is not possible or when the animal's quality of life is severely diminished. This procedure is performed with the intent of minimizing pain and distress for the animal, often utilizing humane methods and medications designed to ensure a peaceful passing.

In contrast, the other options focus on processes that aim to improve an animal's health or extend their lives. Rehabilitating sick animals, providing medical treatment for chronic diseases, and conducting surgeries on healthy animals emphasize recovery, treatment, and management rather than the ending of life. These actions are aimed at sustaining and enhancing the well-being of animals rather than fulfilling the compassionate purpose of euthanasia, which is to offer relief from suffering.
