Bolivia Study Records Over 4,600 Images of Rare Dog

Why this is here: The research team analyzed 4,635 photos, representing 594 separate events, to gather data on the elusive short-eared dog’s behavior and habitat.

Robert Wallace, a biologist with the Wildlife Conservation Society in Bolivia, and colleagues compiled over 4,600 camera-trap images during a 23-year study to document the short-eared dog within the Bolivian Amazon. The species, locally known as the ghost dog, is one of the least-known canids globally and depends on intact forest habitats for survival.

Researchers focused surveys on the Greater Madidi-Tambopata Landscape and the Llanos de Moxos Biocultural Landscape. They systematically reviewed existing records and deployed camera traps annually during the dry season. These efforts revealed the dog prefers mature, lowland forests and avoids more open areas.

The study notes the short-eared dog—measuring 70 to 100 centimeters long and weighing 9 to 10 kilograms—is solitary and primarily active during the day. While camera traps suggest the species may be more abundant than previously thought, direct sightings remain rare due to its skittish nature. Further research is needed to fully understand its population dynamics and ensure its long-term survival.
