There is no definitive answer to this question, as the term “veterinarian” did not enter into general use until the 1600s. Nonetheless, it is known that many animals were brought to castles at this time for medical treatments.
One of these was “the dog,” a type of small hunting hound which played an important role in the training process for knights as well as working alongside them during hunts.
Other common medieval animals trained by nobles included horses and dogs—including canines such as mastiffs, German shepherds, Irish wolfhounds (or wolfdogs), Norwich terriers (which are thought to be the ancestors of modern American kissing bugs or Old English sheepdogs), pointers, setters and spaniels.
