Abstract: A powder dispensing brush for use in dispensing medicated powders or flea control powder onto the body of a pet comprises a hollow elongate handle provided with an end opening closed by a snap-lock closure through which the powder is inserted into the handle interior. The handle itself is formed to provide a grasping surface over one longitudinal segment thereof and an applicator segment on the remainder of its structure. Formed on one lateral surface of the applicator segment are a plurality of conical projections each provided with a central vertical port communicating with the interior cavity of the handle. It is through these ports that powder deposited in the handle is dispensed onto the skin of the animal. In order to control the flow rate of the powder there is further included inside the handle a sliding plate provided with a plurality of openings disposed to align, along one point of the sliding stroke with the ports in the projection.
