  • Patent number: 6371055
    Abstract: A dog leash which incorporates a personal security device. The dog leash includes a handle with an ergonomically shaped body that is also padded to facilitate comfort of use. Disposed substantially inside a substantially watertight cavity defined by the handle is a personal security device. The personal security device includes an audible alarm, a battery, and an activation switch selectively operated by the user so as to activate the audible alarm. A hand loop is connected to one end of the body so that when a user's hand is inserted through the hand loop the user's hand may thereby grasp the ergonomically shaped body, and be proximately disposed with respect to the activation switch of the personal security device. A snap swivel is attached to the other end of the ergonomically shaped body, and a split ring depending from the snap swivel removably engages one end of a lead. The other end of the lead has a coupler for attaching the lead to a dog collar.
