A surgical tray for holding an animal in place in a dorsally recumbent position is made in the form of a shell contoured to conform generally to the back, neck and head of the animal. The shell has raised side wall portions on it in the vicinity of the head and thorax area, and scapular shoulder rests for the animal. Openings are placed adjacent the positions of the front and rear legs of an animal placed in the shell; and a detachable leg strap is led around the leg of an animal and passes through a corresponding opening in the shell for holding the animal in place. The shell is designed to raise the bottom above a table surface on which it is placed; and drain holes through the shell are employed to drain fluids from it.
