A brush may be mounted on a typical flap-style pet door. As the pet uses the pet door, the brush may automatically sweep dirt, loose hair, leaves, grass, allergens, or other debris off the pet. The result may be both a cleaner pet and a cleaner house, as the debris may be brushed off the pet prior to the pet entering the house. The pet owner need not be present for the brush to reap its benefits. |
