Abstract: A multi-purpose utility vest for a pet incorporates a body portion, and a pocket assembly carried by the body portion. The pocket assembly includes overlying outside and inside pocket layers. The outside and inside pocket layers are formed together along a dividing line to define first and second isolated utility compartments having respective first and second access openings for receiving and storing articles therein. A bag-dispensing grommet is attached to the outside pocket layer, and defines a small hole communicating with the first utility compartment for dispensing disposable plastic bags stored in the first utility compartment.
