What type of dispatch method involves using a firearm?

The type of dispatch method that involves using a firearm is shooting. This method is commonly employed by game wardens and other wildlife officials to quickly and humanely euthanize animals that are injured, dangerous, or suffering. Shooting ensures a swift end to the animal's distress and is often considered one of the most humane options available under such circumstances.

Other methods, while they may have their specific contexts and uses, do not involve firearms. Drowning and blunt force are not only less humane but can also lead to prolonged suffering for the animal involved. Snaring is a trapping method and while it can subdue an animal, it does not involve the direct and often immediate dispatch associated with firearms.
