A pet washing collar includes a flexible permeable hose for placement around the neck of a pet. A hose coupling delivers water into the interior of the hose which distributes water around part of the neck of the pet. In some embodiments, the flexible permeable hose includes inner and outer tubes. A length adjuster allows lengthening and shortening of the collar to accommodate pets of different size. A buckle connects ends of the collar together to allow it to be placed and removed from a pet. The effective water distributing length of the hose is adjustable by selectively pinching off part of the hose.
