The device of the dog toilet for the creative action includes a tail clamp, which is designed with the concept of hairpin to clamp the dog's tail, and then a universal joint is connected at the tail, the upper end of the universal joint is connected with a round head at the lower end, so that the universal joint can move freely from up to down, left and right, and aim at the dog's buttocks without directionality, so that the dog's tail can be tilted or tilted. Those with drooping tail can aim at the dog's stool accurately to ensure that it will not leak out.This creation focuses on using the principle of hairpin, using three fixed claws to grasp the dog's tail, and the inner layer uses the super soft silicon Likang material to make contact with the tail, so that the dog does not feel oppressed. When the dog poops, it can accurately get into the bag without slipping off. No matter it is muddy or dry hard poop, it can be very accurate and not easy to miss.本創作行動用狗大便器的裝置，包含有一個夾尾夾子，用髮夾概念設計，來夾住狗的尾巴，然後在尾部接上一個萬向的接頭，其萬向接頭的上端跟下端各接上一個圓頭，使萬向接頭可以上下左右的自由活動，無方向性的來對準狗狗的屁股，讓狗狗不管是尾巴翹著或者是尾巴下垂情況，都能夠很準確的對準狗狗的大便，確保不會掉漏在外。本創作的重點在於運用髮夾原理，用3個固定的爪來抓住狗的尾巴，並且內層用超軟矽利康材料來做接觸尾巴時，讓狗狗沒有壓迫的感覺，當狗狗大便的時候能夠準確的大入袋子內，不會滑脫，不管是稀泥的或者是乾硬的大便，都能夠很準確而不易遺漏。
