A truly ancient breed whose history is foggy at best, the Transylvanian Hound has existed for many centuries, and possibly dates back as far as the 9th century. Many believe that the Transylvanian Hound descends from the Hungarian Magyar Ag?r, though this is difficult to prove. What is known, is that during the middle ages, this breed was popular amongst nobility, who used the Transylvanian Hound as a hunting companion.
