Abstract: A safety harness for restraining a pet in an automotive vehicle includes a fabric jacket having a closed bottom portion for covering the chest and forequarters of the pet, and an open top portion. Adjustable belts extend across the front and rear of the open top portion for securing the jacket on the animal's body. In addition, a pair of detachable and preferably adjustable straps extend diagonally across the animal's back from the sides of the fabric jacket to fasten elements located on the vehicle floor or other rigid structure.
