A simple, small, light weight and economical device for catching and holding a dog's waste before it falls on the ground. The device would be held on the dog's tail by a fastener with a simple clip mechanism. Two flexible retractable arms, in the shape of a trapezoid with no base, are attached to the fastener enabling a simple adjustable folded diaper to be caught and placed in the right position to catch and hold the dog's waste before it falls on the ground or grass. When not in use the device might be folded and become compact and easy to carry.
