Abstract: A weighted pet leash assembly including a housing for containing the leash in a retracted condition. The housing includes a handle which is integrally formed with a handle of a hand weight such as a dumbbell such that gripping the dumbbell handle places the finger of a user proximate the leash assembly trigger for selectively activating a stop mechanism to terminate travel of the leash through an opening in the leash housing. The weighted pet leash assembly can be used in combination with a conventional dumbbell or other hand weight such that each arm of the user is being exercised simultaneously.
