Abstract: A collar and leash assembly is provided, comprising a strap, preferably constructed from nylon or similar fabric, having a first end and a second end, wherein the first end includes a first fastener, and wherein the second end includes a second fastener. A loop is formed into the first end of the strap, and the loop is closed adjacent to the first fastener. A third fastener is slidably connected to the loop of the strap, and a fourth fastener is slidably connected to the strap between the loop and the second end. Preferably, a releasable clip is slidably connected to the loop for optional connection to an existing animal collar. The strap can be configured into a long leash, short leash, or collar configuration depending upon the connections between the various fasteners.
