  • Patent number: 4321888
    Abstract: A ball with extending tethers serves as a toy especially for small dogs. Two molded hollow halves adhered together to form the ball are each formed with at least two and preferably four integral cylindrical interior passageway embossments, equally spaced, which when aligned with those of the other half, create watertight passageways arranged as chord orientated openings, perpendicular to the geometric plane that is common to both the halves, for receiving and securing portions of the tethers. Each tether extends outwardly from the molded hollow watertight ball a sufficient distance to be well gripped in the teeth of small dogs. Optionally, loose small objects, such as metallic balls, are placed within the two molded hollow halves, before they are adhered together, creating their internal watertight space. The movement of the balls creates interesting sounds when the ball is being played with by small dogs.
