A restraining apparatus for an animal including a combination of a leash and a harness to be used in conjunction with a collar. The restraining apparatus includes a ring defining an opening. A coupling element for fastening to a collar on the animal is mounted to the ring. A substantially rigid arm is mounted to the ring and extends to a free distal end spaced from the ring, with the arm forming a substantially elongated opening with the ring. A leash may be attached to the ring. When the restraining apparatus is applied to the animal as a harness, the coupling element is fastened to the collar, and the leash is wrapped around the torso of the animal, engages the arm at the elongated opening, and may freely slide and tighten around the torso of the animal.
