The gentleman went on to explain that, over a period of years, he had converted several men to dogs. Some he sold, as he put it, "for a nice profit". I guess this is a cottage industry and there is a niche market for these "mogs" (man/dog). These "hobbyists", as he called them, are well to do and very educated. They come from all parts of the country. They have little get-togethers on the weekends where they put their pet "mogs" into a big circular pen and watch the "mogs" play with each other. The "mogs" may also mount and hump each other.
