The appearance of the Brazilian Terrier is typical of dogs descended from fox terrier types. The short coat is tri-colour. The skull is flat and wedge-shaped, with folded ears. The tail may be docked or natural.
Brazilian Terriers are alert, intelligent and playful with stronger than average hunting instincts. They should not be left alone with small animals. They must be kept active and occupied, becoming destructive or restless if bored.
