The fox is a canine beast with a narrow snout and bushy tail; its reputation is one of slyness and craft. It is found in the canting arms of Fuchs, c.1450 [Ingeram 149]. If blazoned a “vixen”, the female fox is intended.
The fox seems to have no default posture; the illustration shows a fox courant. Society heraldry defines a “fox proper” as red, with black “socks” and a white tip on the tail. For related charges, see dog, hyena, wolf.
