The pet grooming tunnel is a device that is adapted to brush hair or fur of an animal. The pet grooming tunnel is constructed of a ring member that includes a plurality of brush bristles provided on an inner surface. The ring member is supported in a vertical orientation via support legs provided on opposing sides of the ring member. The support legs are each vertically, adjustable so as to raise and lower the ring member with respect to a support surface. The plurality of brush bristles are concentrically oriented. An alternative embodiment includes a wider ring member wherein the plurality of brush bristles form a truncated conical opening.
