Abstract: A diaper for a dog or other small quadruped comprises a textile body band and tail band forming a T with fasteners at one or both ends of the body band and the end of the tail band and an absorbent pad affixed to the inside surface of the tail band at its junction with the body band. The body band is wrapped around the dog's body with its ends on its back and those ends are connected by their fasteners. The tail band is brought over its rump and back and fastened to the body band ends at their junction so that the absorbent pad is against the dog's genital and anal areas. The tail band may be unitary with an opening for the dog's tail, or bifurcated.
