Retractable snap-on leash
View Patent ↗Improvements in a retractable Snap-On Leash is disclosed. The Snap-on Leash is always on the collar and can be used on nearly any collar that is available in the market place. This further allows the retractable snap-on leash to be removed and placed on a different collar when as the animal grows and when the collar wears out or is damaged. The owner simply needs to locate the handle to extend the leash. A lanyard retainer, stop or lock can be incorporated to limit the extension length less than the length of the leash spooled in the housing. The retracting mechanism allows the leash to be retracted automatically at the end of a walk or as the dog changes distance from the owner. The handle conforms to the shape of the housing to minimize a surface that can catch on anything that the dog might encounter.
