A pet accessory is disclosed. The pet accessory comprises a strap, a bag and an attachment means that attaches the strap to the bag. The strap has sufficient length to be used as a leash and has a releasable catch at a first end for attaching the strap to a pet. The bag defines an interior volume for containing objects. The attachment means attaches the bag to the strap such that the pet accessory is adaptable to form a carry bag whereby the strap forms a handle or shoulder strap for carrying the bag and to form a pet leash with the bag attached and with the strap forming a hand loop in a portion of the strap opposite to the first end for restraining a pet.
