A system for restraining a pet while washing or for any other reason. A wash bag is made from mesh material that protects and confines the pet. The bag acts effectively to prevent the pet from running away or moving too much while still allowing complete access to the pet for washing. In the top front center of the bag, there is an opening for the pets head to emerge. The top of the bag has an end-to-end zipper allowing the bag to completely open from the top and back so that the pet can step into it. There are usually two openings on the side of the bag that allow placement of the hands inside the bag for washing. The pet may lie down or stand up without any harm or discomfort. A drawstring can adjust the neck opening to fit the animals neck size.
