The invention relates to a stabilising device for animals for medical treatment, for relieving strain, stabilising, securing, and to enable them to be lifted horizontally and carried, comprising various components. These include a flat belly element, which is designed to be attached in the belly region and has a flexible, anatomically adaptable supporting area and at least four connector elements with first closure means arranged thereon. The components of the stabilising device further include a flat back element which is designed to be attachable in the back region, and has at least one means for stabilising at least partially to the longitudinal axis, and at least four corresponding second closure means. The at least four connector elements are arranged on the belly element at a distance from each other mirror symmetrically to the longitudinal axis of the belly element. The belly element is further designed to be detachably connectable to the back element via the connector elements with the first closure means arranged thereon and the corresponding second closure means, wherein the number of first closure means is equal to the number of corresponding second closure means.
