Introducing the Dhole
A Dhole (Cuon alpinus) is a wild canid species found throughout areas of Central, South, and Southeast Asia (SandiegoZoo.org). They are also known as Asiatic wild dogs, Indian wild dogs, red dogs, and whistling dogs. Dholes have a fox-like appearance with a long muzzle, pointed ears, and a bushy tail often with a black tip. Their coat color ranges from charcoal gray to tawny and they typically have a lighter underside and white feet (PBS.org). Adult dholes measure 70-110 cm (27.6-43.3 in) from head to tail and weigh around 12-18 kg (26-40 lbs). They have a slender, long-legged body built for stamina and speed when hunting prey across long distances.
Dholes inhabit a wide range of habitats including grasslands, scrublands, tropical rainforests, savannas, alpine areas and desert edges. They once ranged throughout much of Asia but their numbers have declined over the decades due to loss of habitat and prey base, along with disease spread from domestic dogs. Today wild dhole populations are fragmented but can still be found in areas of India, Thailand, Malaysia, Indonesia, and parts of Central Asia (TheAnimalFacts.com).
Dhole Behavior
Dholes exhibit highly social behavior and frequently hunt in packs of 5 to 12 individuals. These clans can grow as large as 30 or 40 members.[1] Pack hunting allows dholes to pursue and takedown prey much larger than themselves, including sambar deer and wild boar.[2] When hunting, dholes rely on relays to exhaust prey animals. Different groups chase the prey in turns until it collapses from fatigue.
Dholes are also very vocal animals. They make a wide range of sounds including whines, mews, yaps, squeaks, screams, growls and chatter calls.[3] These vocalizations help coordinate the pack when hunting and defend territory. Dholes are territorial and mark their ranges with urine, feces and anal gland secretions. Howls and other calls also help the pack stay in contact over large distances.
In addition to their social nature, dholes are incredibly athletic. They can run fast, swim efficiently, and jump impressively high.[2] This physical ability allows them to tire out fleet-footed prey during long chases.
Dhole vs Dog Comparison
Dholes may resemble domestic dogs in appearance, but there are some key differences in their anatomy, social structure, and hunting behaviors.
Anatomically, dholes have larger skulls, longer limbs, and narrower rib cages than most domestic dogs 1. Their nose structure is adapted for scent tracking during the hunt. While many breeds of domestic dog have floppy ears, dhole ears are erect to enhance hearing. Dholes have partially webbed feet which aids their ability to chase prey through wet terrain 2.
Socially, dholes live in hierarchical packs with a dominant breeding pair, similar to wolves. However, domestic dogs do not adhere to rigid pack hierarchies when socializing in groups. Dhole packs also exhibit cooperative breeding and cub rearing, whereas domestic dog parenting roles are not shared amongst a pack 2.
When hunting, dholes rely on stamina, teamwork, and relays to pursue and tire out fleet-footed prey across long distances. Most domestic dog breeds do not display the same level of endurance and persistence when chasing prey. Additionally, dholes have unique physical adaptations that aid their ability to consume and digest bone, which differs from domestic dogs 1.
Taxonomic Classification
The dhole (Cuon alpinus) belongs to the canid family, which includes dogs, wolves, foxes, jackals, and other related species. This places the dhole in the taxonomic order Carnivora and the genus Cuon. There are four distinct subspecies of dhole across its range in Asia.
Despite some similarities with other canids, the dhole is the only living species in its genus Cuon. This makes its taxonomic classification distinct from the genus Canis, which includes the gray wolf, coyote, golden jackal and other wolf-like canines. So while the dhole shares common ancestry and traits with dogs, it is considered its own separate genus.
Some key differences between the dhole’s genus Cuon and the genus Canis which includes dogs, wolves and jackals include the dhole’s smaller size, lack of dewclaws, unique dentition, and adaptations for pack hunting behavior.
So in summary, the dhole’s taxonomic classification places it in the canid family, but as a distinct species and solitary member of its own genus Cuon, separate from dogs and wolves in the genus Canis. Despite some dog-like characteristics, the dhole’s evolutionary lineage and adaptations make it a unique canid.
Diet and Hunting
Dholes are carnivorous and prey primarily on hoofed mammals. In India, their main prey animals include deer, wild pigs, buffalo, and wild goats https://animals.sandiegozoo.org/animals/dhole. In Southeast Asia they feed on deer, gaur, and banteng. And in Siberia, their prey consists of deer, wild sheep, and reindeer https://www.pbs.org/wnet/nature/blog/dhole-fact-sheet/.
Dholes are cooperative hunters that live in large packs, allowing them to take down prey much larger than themselves. They use teamwork and relay hunting to exhaust and overwhelm their prey. A pack will tenaciously pursue large prey over long distances until it tires and can be brought down. Once prey is caught, dholes tear open the belly and eat the entrails first while the prey is still alive. They consume most of the carcass, including bones, leaving little behind.
As carnivores that feed primarily on large ungulates, dholes play an important ecological role in regulating and controlling populations of herbivorous animals. Their predatory behavior shapes the abundance, distribution, and evolution of their prey species. As pack hunters, they are able to exert significant predation pressure on large prey populations.
Reproduction and Life Cycle
DHoles have a distinctive breeding season that takes place over about four weeks in late autumn and early winter, usually in November and December. During this time, the pack divides into small groups consisting of an adult male and female pair and their offspring from previous litters. These small family units spend two weeks courting, reinforced by elaborate greetings, play, and friendly interactions between the male and female.
After courting concludes, a two week breeding period follows. The female gives birth to a litter of 4-6 pups after a gestation period of around 60-70 days. She remains at the den nursing and caring for the pups while the rest of the pack hunts and brings back food. The pups open their eyes after about 10 days and emerge from the den around three months old. They are weaned after 6-8 weeks but remain dependent on regurgitated food from the pack while they learn to hunt. Sexual maturity is reached at around one year old and dholes may live up to 15 years in the wild.
Throughout the breeding season, the adult breeding pair remains monogamous. However, dhole packs do not maintain permanent breeding pairs across different seasons, so males and females may mate with new partners each year.

Habitat and Range
The preferred habitat of dholes are the dense forests and grasslands of Asia [1]. They are highly adaptable to a variety of climates, from the freezing winters of Siberia to the tropical forests of Indonesia [2]. Historically, dholes had an extensive range across much of Asia. However, their distribution has become fragmented due to habitat loss and hunting.
Dholes could once be found from eastern Siberia to Indonesia. Their range extended from India to Malaysia and northwards to Russia [1]. Today, dholes have disappeared from much of their former range. They can still be found in small, scattered populations in central and east Asia. This includes countries such as India, Thailand, Cambodia, and parts of China and Russia [2].

Conservation Status
Dholes are listed as Endangered on the IUCN Red List, with populations decreasing and estimated to comprise fewer than 2,500 mature individuals as of 2018. Their numbers have declined due to habitat loss, depletion of prey populations, persecution due to livestock predation, and disease transfer from domestic dogs.
According to the San Diego Zoo, disease and human conflict threaten dholes, which are now listed as an endangered species. Their supply of prey is also running out in several areas. Dholes can no longer be found in over 75% of their former range.
The Wildlife Conservation Society states that the major threats to dholes include habitat loss, loss of prey species, and diseases from domestic and feral dogs. Remaining populations are small and fragmented outside of India and threatened by growing human populations and development.
Cultural Significance
The dhole has been featured prominently in the mythology and folklore of native Asian cultures. In Hindu mythology, the dhole was considered a sacred animal and was associated with Lord Dattatreya. There are also folk tales from India and Nepal that portray the dhole as a clever, courageous, and loyal creature.
In Chinese mythology, the dhole was viewed as a guardian spirit and symbolized courage and loyalty. There are legends of dholes guiding lost travelers and protecting people from harm. The dhole was seen as a defender of righteousness in ancient Chinese folk religion.
Across Tibet and Mongolia, the dhole played various symbolic roles. They were respected as intelligent hunters and parents. Dholes were believed to mate for life, making them symbols of loyalty and fidelity in Mongol tribal customs. However, dholes were also feared for their fierce attacks on livestock.
The dhole appears frequently on artifacts, totems, and in literature from ancient Asian cultures. They are portrayed as clever, social creatures with close family bonds. However, they are also shown as relentless hunters capable of bringing down large prey. The cultural significance of the dhole reflects a mixture of reverence, admiration and apprehension.
Conclusion
The dhole is an elusive and remarkable animal that bears some similarities to domestic dogs, but also many differences. Also called the Asiatic wild dog or red dog, it is not technically a member of the canine family, but is instead a distinct species of its own in the genus Cuon.
Like dogs, dholes are highly social and intelligent pack animals with complex vocal communications. They have many dog-like features as well, including a flexible social structure, cooperative hunting, and male-female pair bonding. However, dholes diverge from dogs in their appearance, taxonomic classification, reproductive habits, and other traits.
While dholes may look and sometimes act like dogs, genetic analysis shows they belong to a separate evolutionary lineage. Their taxonomic classification puts them in the family Canidae along with true dogs and other canids, but in their own distinct genus Cuon. This reflects their unique evolutionary history.
In summary, the dhole is best described as a wild canid that shares common ancestry with dogs, but is definitively not a true dog itself. It is a fascinating animal uniquely adapted to its environment and social structure. With continued habitat loss and human persecution, the future of the dhole remains uncertain. Increased awareness and conservation efforts are needed to protect this remarkable canid species.
