Restraining an animal typically involves using physical or mechanical means to limit its movement or behavior. This can be done for various reasons, such as for medical treatment, grooming, or training. Some common methods of restraining animals include using a leash or harness, a crate or cage, a muzzle, or physical restraint by holding or immobilizing the animal. It is important to use appropriate and humane methods of restraint to ensure the safety and well-being of the animal.
