Susan Silberman of Fl started a yahoo group, http://pets.groups.yahoo.com/group/PPasoRescue/ , for such listings and for short term homes for victims of disasters like floods and hurricanes. There are a number of listings already there. This group also lists Paso Finos and an occasional gaited horse of another breed. Feel free to join and list there or look over the listings for a companion to your horse. Some are said to be riding sound.
