โThe dhole has been described as a mix between the gray wolf and the red foxโ
Also known as the โAsiatic Wild Dogโ, Dholes are once a wide-ranging wild dog species that covered nearly half the globe. Today the dhole is an endangered species with an estimated population of fewer than 2,500 adults. Dholes are animals that inhabit dense jungles, steppes, mountains, scrub forests, and pine forests. These Asiatic wild dogsโ coloring can range from charcoal gray to red or brown with yellow, white, or otherwise light-colored highlights. Despite being members of the dog family, dholes do not bark or howl, but they have unique screams, chattering, clucking, and whistles that they use to communicate and hunt with.
Incredible Dhole Facts!
- While the dhole is closer in stature to a German Shepherd dog, it more closely resembles a fox in appearance.
- These wild dogs once ranged over all of North America, Europe, and Asia, but 12,000 to 18,000 years ago they were reduced to their current habitat of eastern and southern Asia.
- An adult can eat 2.2 lbs of meat in four seconds, and it can later regurgitate it to feed other members of its pack.
- Dhole packs have killed leopards and tigers, and they have even been known to attack Asiatic black bears.
- Dholes are able to run at speeds of up to 45mph.
Scientific Name
The dhole, also known as the Asiatic red dog, Indian wild dog, or mountain wolf, has the scientific name Cuon alpinus. The dhole is a member of the family Canidae and the class Mammalia.
While it is a close relative of animals within the genus Canis, there are several distinct differences. The dholeโs skull is concave, it is missing a third lower molar, and the upper molars possess only one cusp.
Origin Of The Species
It is believed that the dhole is a descendant of a jackal-like animal from the Pleistocene era.
It is believed that the dhole is descended from an ancestor that is jackal-like and was found in the Pleistocene era where it prowled throughout Europe, North America, and Asia. It became confined to its current location around 12,000 to 18,000 years ago. Thought to be the forbearer of the dog, the dhole was formally given the genus name Canis. Although is it still close, genetically, to the Canis species, when it was noted how different the two animals were, it was later changed to the genus Cuon.
Types Of
The dhole, while originally thought to contain two species, is in fact just one species that could possibly be made up of as many as 11 subspecies, although currently there are 7 subspecies recognized. These 7 are:
Burmese dhole (Cuon alpinus adjustus).
Ussuri dhole (Cuon alpinus alpinus)
Tien Shan dhole (Cuon alpinus hesperius)
Sumatran and Javan dhole (Cuon alpinus sumatrensis)
Cuon alpinus fumosus
Cuon alpinus lepturus
Cuon alpinus laniger
Appearance And Behavior
The dog is about 30 to 40 inches long, in addition to an 11 to 19-inch tail, and it can weigh anywhere between 30 to 46 pounds. Depending on the region, they can vary in color from a yellowish hue to a darker red-brown color. They do have lighter coloration along their chest, belly, and paws.
The average dhole, including its tail, is about as long as R2D2, of Star Wars fame, is tall. Males typically weigh more than females and are larger. While they are fox-like in appearance, dholes are more akin to a medium to large-sized dog.
Dholes are highly social animals, and they frequently hunt in packs of 5 to 12. These clans may grow to as many as 30 or 40 members. These wild dogs are carnivores, and they generally hunt deer or sheep. However, there have been recorded instances of dholes attacking animals as large as a tiger or bear.
Dholes are also very vocal animals. As a member of the dog family, they whine and growl much like your family pet. Unique to these animals, though, is a series of clucking noises and screams that are not found anywhere among other canines. They are also known to communicate through whistling and chattering while hunting.
Unlike other canid species, dholes very rarely display in fighting behavior. It may even be difficult to pick out the dominant male-female pair of the pack. They work as a unit to rear the packโs pups, and the young adult animals are free to join other packs without trouble upon reaching maturity.

Habitat
Dholes are wide-ranging, and they are found throughout Eastern and Southeastern Asia. Once, these wild dogs could be found across North America, Asia, and Europe. Around 12,000-18,000 years ago, they were reduced to specific areas within the Asian continent. Dholes can now be seen as far north as Siberia, as far south as some Malaysian islands, and as far west as the Indian peninsula. Due to the vast area they can be found in, they survive in an equally wide variety of habitats such as
- Dense forest
- Scrub forest
- Plains
- Mountains
- Jungles
Dholes, like other dogs, cover a large area. Their average territory can be 34 square miles. Thatโs larger than the entire area of Manhattan! As such, they are extremely fast runners, swimmers, and jumpers.
Dhole dens are typically underground and may be simple or very complex with many tunnels. Dholes have even taken over jackal dens. The entire pack will inhabit one den and may utilize multiple entrances.
Diet
Dholes are carnivores and tend to hunt in packs.

As mentioned earlier, Dholes are carnivorous. Primarily they hunt hoofed mammals in packs; however, due to their vast habitat, they are highly adaptable, and they hunt whatever is available in that specific region.
Their need for enough food is actually the reason for such a large habitat to begin with. The dhole hunting parties take down their prey, swallow large portions of it whole, and then transport it back to the rest of the pack. Dholes have even been known to eat over one kilogram of meat in under four seconds; thatโs as heavy as three-quarters of a human brain!
In smaller packs, and alone, they will eat proportionally smaller prey consisting of rabbits, lizards, mice, etc.
Predators And Threats
The dhole is not specifically prey for any other predator. Tigers, leopards, and other predators that share a habitat with the dhole have killed them, but the reverse is also true. The primary source of conflict between these higher-level predators is because of food scarcity.
The major threats faced by the dhole are not from other animals. Dholes are suffering from habitat loss specifically due to deforestation for agricultural, residential, and commercial purposes. This habitat loss leads to a decline in available prey, and it increases the subsequent threat of competition from high-level predators in the area.
Also, related to this loss of habitat is the persecution of the dhole by humans in the area. Failing to find adequate food from their usual prey source, they adapt and occasionally hunt domesticated animals. The resulting retaliation from farmers has been devastating to the dhole population as a whole.
Disease has also proven to be a major threat to them. Their exposure to pathogens has drastically increased with their proximity to, and association with, domesticated dogs as well as their predation of other domestic animals.
Reproduction, Babies, And Lifespan
A dhole pup has a growth rate similar to a coyote.

A dhole pack will typically contain more than one breeding female. In the wild, they have been observed to mate from October through January, but this may vary in captivity. A baby dhole is called a pup. They are born in large litters typically consisting of 5-10 pups but sometimes as many as 12 to 16.
The gestational period is approximately 60 days, and the babies are suckled by their mothers for a period of similar length. During this time, any pregnant females share the den and the pups interact freely. While their mothers ween them, the entire pack helps feed the pups by regurgitating their food.
The pups grow much faster than wolf or dog pups. Their growth is more similar in rate to that of a coyote. By six months, the pups are accompanying the pack on hunts, and at eight months old they take on active roles in the hunt.
After maturing, dholes can leave the pack and join another without the challenges or fighting that is common in other wild dog species. Typically, around the age of three, females leave the pack to join another. In the wild, the average lifespan for these animals is around 10 years. Captive dholes average 15 to 16 years of life.
Population
Dholes suffered from loss of habitat and lack of prey.

The true population size of the dhole is very difficult to assess. Their tendency to inhabit locales that are sparsely populated, or contain unfavorable terrain, makes it nearly impossible to get a firm figure for their population. In addition, dholes, in areas that have been studied, have frequently experienced wild population swings over short periods of time.
The best estimate is a total population of between 949 and 2,215 adult animals that remain in the wild. For that reason, these wild dogs are listed as endangered, and the population is assumed to be in continued decline.
In The Zoo
There are only three places in North America where you will find these wild dogs. The Minnesota Zoo, the San Diego Zoo, and The Wilds operated by the Columbus Zoo, all have captive dholes. Notably, the staff at The Wilds have recently hand-raised a litter of pups when their mother died shortly after birthing them.
