The term Bandog (also known as Bandogge) originated around 1250-1300 in Middle England referring to a mastiff type dog that was bound by a chain during the daytime and was released at night to guard against intruders. In 1570 Johannes Caius published a book in Latin which in 1576 was translated into English by Abraham Fleming under the name Of Englishe Dogges in which he described Bandog as a vast stubborn eager dog of heavy body.
