The Short-eared Dog has short and slender limbs with short and rounded ears. The Short-eared Dog has a distinctive fox-like muzzle and bushy tail. It ranges from dark to reddish-grey, but can also be nearly navy blue, coffee brown, dark grey or chestnut-grey, and the coat is short, with thick and bristly fur. Its paws are partly webbed, owing to its partly aquatic habitat.
It moves with feline lightness unparalleled among the other canids. It has a somewhat narrow chest, with dark colour variation on thorax merging to brighter, more reddish tones on the abdominal side of the body. This species possesses a large elongated head and long canine teeth, protruding even when its muzzle is closed. Its back often has a dark streak, while a brighter stain is on its tail. Like all canids, it has 42 teeth.
Typical height at the shoulder is 25-30 cm. Its head and body length is about 100 cm, with a tail of about 30-35 cm. It weighs about 9–10 kg.
This wild dog is mainly a carnivore, with fish, insects, and small mammals making up the majority of its diet. An investigation led in Cocha Cashu Biological Station in Peru into the proportions of different kinds of food in this animal's diet produced the following results: fish 28%, insects 17%, small mammals 13%, various fruits 10%, crabs 10%, frogs 4%, reptiles 3%, birds 10%.
