The Ariegeois normally weighs approximately 28–30 kg. Males should stand 52–58 cm tall, and females 50–56 cm. The coat is smooth and short, white with clearly defined black markings; it is sometimes mottled, and there may be tan points at the head. The head of the dog is lean and elongated. There are no wrinkles. The eyes are dark and gentle. The ears are very soft and medium-length. The muzzle is of medium length, and the nose is black. The neck is slender and arched slightly, to the chest which is narrow and deep. The ribs are well-sprung with a strong, sloping back. It should have straight forelegs and strong, powerful hindlegs. The feet are hard and foxlike. The tail is slightly curved. Overall, the Ariegeois is a talented scenthound, and affectionate and serene in the home. The Ariegeois is now being bred in Italy and used to hunt wild boar, performing well in this endeavour under Italian conditions.

Good speed; a degree of endurance not generally found in hounds of this size. A surprisingly deep, powerful voice and remarkable scenting ability. Of even temperament, essentially friendly and social. As a hunting/working scenthound breed, and being called upon to work in close proximity with other hounds and their handlers, aggression towards other hounds and people is to be considered a fault.
