  • Patent number: 6792893
    Abstract: A retractable leash for two animals which includes two spool assemblies (24A and 24B) for individual extension and retraction of each animal's cord. Each animal's cord is controlled by a button and locking mechanism. The cord holes (20A and 20B) where the leash cords (12A and 12B) exit are opposite of each other to minimize or prevent entanglement. If the leash cords cross, the operator need only rotate the lease handgrip (38) to uncross the cords. In one locking design, braking and locking buttons (18A, 18B, 18C, 18D and 16A, 16B, 16C, 16D) are placed on both the top and bottom of the leash handgrip (38) so that the operator may turn the leash and be immediately ready to control the forward movement of the animals. The leash may also be adapted to mount on the animal's collars as separate units which fasten together to form one walking leash.
