The pet harness with restraint includes a rigid lateral bar or rod attached across the shoulder strap of a harness. The bar serves to prevent the animal from escaping between the vertical uprights of a fence or similar enclosure. The harness preferably comprises a pair of foreleg loops, a chest strap interconnecting the foreleg loops, and a pair of connecting straps that extend from the loops over the shoulders of the animal. Alternatively, the harness may comprise a collar portion and a body-encircling strap joined by longitudinal chest and dorsal straps. The bar may be permanently attached to across the shoulder or dorsal straps of the harness, but is preferably removable to provide a versatile harness. The bar may be attached to the harness by snap fasteners, by insertion into a sleeve attached to the harness, etc. The harness may include elastic sections therein to provide greater adjustment for growing pets.
