Abstract: A housing has a top, a bottom, and a side wall. A spacer is coupled to and depends downwardly from the bottom of the housing creating a chamber beneath the bottom of the housing within the spacer. A rod is has an upper end within the housing and a lower end there beneath. Drive mechanisms located within the housing and coupled to the rod reciprocate the rod between a retracted position and an extended position. The retracted position is with the lower end within the chamber. The extended position being with the lower end extending beneath the chamber.

Abstract: A muzzle formed of a flexible sheet has a top, a bottom, and laterally spaced sides. A central hole in the muzzle is equally spaced from the sides, closer to the bottom than to the top. Two laterally spaced side holes are in the muzzle between the central hole and the sides. A restraint in a generally rectangular configuration has opposed free ends. Open windows on each side of the restraint allow access to the jugular furrow. Flaps secured by hook and loop fasteners cover the open windows and pivot from a vertical edge. Fasteners are secured to the restraint adjacent to the free ends. Attachment elements couple the muzzle and the restraint.

Abstract: A windowed muzzle has left and right side sections, a lower section, an upper section and a rear section. A left window is in the left side section and a similarly configured right window is in the right side section. A left flap is configured and sized to cover the left window and a similarly configured right flap is configured and sided to cover the right window. A securement assembly selectively retains each flap in a raised orientation above the window or in a lowered orientation covering the window.
