A hand attachable animal washing apparatus, attachable upon the hand of a user, enables singlehanded control of water flow and application of water into the coat of an animal. Control of water flow though a molded body portion is effective by singlehanded operation of a valve assembly disposed interiorly within the molded body portion. A user is enabled to open and close the valve assembly by compressing a compressible portion disposed proximally overlying the user's palm when wearing the apparatus upon one hand. A user may thereby control and apply water applied to an animal with one hand while securing and comforting the animal with the other hand.
