Abstract: An automatic balling gun includes an elongated member having a tubular profile which is easily operated and manipulated by the single hand of the user. A release assembly is mounted along the length of the tubular member to dispense medicine orally to an animal by merely depressing a plunger. A knob is provided on a proximal end of the automatic balling gun which facilitates cocking the gun and loading a dispensing chamber thereof with a capsule or pill to be dispensed. The automatic balling gun can then be inserted into the animal to be treated followed by depressing the plunger on the release assembly to dispense the medication from the gun.
