  • Patent number: 5682840
    Abstract: Restraining devices for use with small quadruped animals are provided. The restraining devices are comprised of a pair of substantially equal length cords, each cord having a first end, a second end opposite the first end and an intermediate portion between the first and second ends. A mechanism is secured to the first end of the cords for receiving at least a portion of the intermediate portions of the cords with the intermediate portions each forming a loop to be disposed within one of the foreleg pits of the small animal whereby an animal straining against a person holding the second ends results in a pressure applied to the foreleg pits of the animal causing the animal to react.

  • Patent number: 5078637
    Abstract: A flexible flying disc used for play by adults and children as a retrieval toy for animals, particularly dogs. The disc is characterized by having an aerodynamic design for long and stable flight similar to rigid discs, yet is made of soft, flexible material which eliminates harm to humans and damage to the mouths of any animal catching it. The lower edge is made of an abrasion-resistant material which allows the disc to land and be skipped off hard surfaces without damaging the disc. A flexible tube within the disc provides a spring type action for maintaining the shape of the disc or for returning the disc to its original shape when the disc is folded or pulled out of shape. When the disc is tossed, it has a circular dome which inflates upwardly providing an air foil effect, while a lower edge, wrapped around the tube defines a toroid which provides a gyroscopic effect lending stability to the flight as the disk spins through the air.
