The extendable, pet sanitation device is a portable device for collecting pet waste, especially from dogs, and includes an ergonomically-contoured shaft having a handle disposed at an upper end and a circular or oval hoop defining a lower end. A net is attached to the hoop and depends downward therefrom. Elastic straps are strategically positioned on the net for securing a disposable bag thereto. The contoured shaft is telescopically constructed so that it can be adjusted to accommodate a person's height.
