A dog feeder that includes a base, a lid, and a coupler. The base includes a left wall and a right wall that extend vertically away from a tray between the left wall and the right wall. The tray is configured to contain dog food. The lid includes a front side and a back side, where the front side includes a protrusion that protrudes outwards away from the back side. The coupler couples the base to the lid such that the lid is capable of swinging between the left wall and the right wall. The protrusion is configured such that when a head of a dog pushes against the protrusion to swing the lid to expose the tray, ears of the dog do not reach an edge of the lid.
