An apparatus for restraining a pet. The apparatus includes a sphere having a weighted center and a chain attached to the sphere and a collar worn by the pet. The chain allows the sphere to hang from the pet. Thus, the movement of the pet is restricted by the added weight of the sphere. Preferably, the sphere includes at least two bars affixed to an outer surface of the sphere. In addition, the chain preferably includes at least two chain extensions. Each extension of the chain is attached to each of the bar. In addition, the chain is of a sufficient length to allow the sphere to roll upon the ground. The sphere may be constructed of a rubberized material. In addition, the chain may be covered by a fabric material.
