The piston is extendable from and retractable into the piston cylinder by sliding movement, and includes a receptacle having an opening. The plunger is positionable in a first loading position relative to the housing to expose the opening to the receptacle such that a medicament is insertable into the receptacle through the opening, and positionable in a second loading position relative to the housing to expose the opening to the receptacle such that an edible composition is insertable into the receptacle through the opening. The plunger is also positionable in an ejection position relative to the housing to eject a pet chew comprising the edible composition and medicament from the receptacle.
