Abstract: A teat cautery bullet or device for insertion through the teat orifice and into the papillary duct of an injured teat of a dairy cow or similar animal to control hemorrhaging and prevent formation of a blood clot in the teat orifice or papillary duct is formed by molding of solid material which is soluble by liquid in said teat to control such hemorrhaging and clotting. The device comprises a nose portion tapered to facilitate insertion, an integral neck portion tapered to facilitate retention, and an integral base portion to facilitate insertion and removal and of such width as to prevent passage or loss of the device upward into the teat sinus.
