Atelocynus microtis
short-eared dog

Atelocynus microtis can be found in northern South America east of the Andes in Colombia, Ecuador, and Peru, as well as south of the Amazon in Brazil. Berta (1986)

The short, thick coat of A. microtis suggests that the animal is often in water or resides in areas of heavy rainfall. Furthermore, its short legs are well adapted for locomotion in dense forests. These conclusions are supported by this animals' distribution--all specimens have been collected in lowland tropical rainforests. Berta (1986)

Atelocynus microtis has a large head, relatively short and slender limbs, and a long bushy tail. The ears are proportionately shorter than in most other species of wild dogs, but protrude well above the crown. The tips of the canines are visible when the mouth is closed. Atelocynus microtis has short and stiff pelage which is brown or blackish, giving way to a dull reddish-brown on the underside. Other markings include a dark band along the top of the back and tail, and a light-colored patch at the underside of the base of the tail. Emmons (1990) ; Berta (1986)

Nothing is known of the behavior of A. microtis in the wild. Observations of this species have been made in captivity. These animals were shy during the early part of captivity but became tame with time. To manifest hostility, they growled, snarled, bared their teeth, and attempted to bite. The males have been seen to assert dominance in most situations, although the females are one-third larger. The tip of the tail of this animal is particulary sensitive and, when the animal is excited, the hairs are erected. Furthermore, when males are excited, they emit a strong musky odor. Observations of the small-eared dog in captivity show that it moves gracefully and lightly, uncharacteristic of other members of the family.

Nothing is known about the food habits of of A. microtis in the wild. Observations of this species in captivity suggest a carnivorous diet, although it has been suggested that it will eat fruit in wild if prey is scarce. Berta (1986)

The small-eared dog appears to be extremely rare throughout its range. It is protected by law in Brazil and Peru and is on the Brazilian list of endangered species. Hoffmann (1982) ; Berta (1986)

The generic name Atelocynus is derived from the Greek words for 'imperfect' and 'dog'. The specific name microtis is formed from the Greek words meaning 'small' and 'ear'. Berta (1986)
