Abstract: A collecting device for collecting animal waste includes a collecting component defining a generally pouch-like container section for receiving the animal waste and a flange-like mounting section extending integrally from the container mouth for mounting the collecting component to the animal. The mounting section defines a tail abutment edge positionable adjacent the tail of the animal. An attachment strap is attachable to the collecting component for releasably securing the collecting component to the animal. A handle and a tab both extend from the mounting section and are usable both for manipulating the collecting component to and for closing the latter once the animal waste has been collected.
