Abstract: A device for administering to animals a treatment liquid stored in a container, the device comprising a hollow loop serving as a flow conduit between the container and a flexible nozzle mounted on one side of the loop adapted to direct a jet of the liquid toward the back of the animal's throat. The loop has a geometry close to that of an equilateral triangle, the corners of which adjacent the side which carries the nozzle being rounded whereby the loop may be clamped very firmly on the nose of the animal without inflicting pain.
