Ecology and behaviour
Dholes produce whistles resembling the calls of red foxes, sometimes rendered as ''coo-coo''. How this sound is produced is unknown, though it is thought to help in coordinating the pack when travelling through thick brush. When attacking prey, they emit screaming ''KaKaKaKAA'' sounds. Other sounds include whines (food soliciting), growls (warning), screams, chatterings (both of which are alarm calls) and yapping cries. In contrast to wolves, dholes do not howl

. Friendly or submissive greetings are accompanied by horizontal lip retraction and the lowering of the tail, as well as licking. Playful dholes open their mouths with their lips retracted and their tails held in a vertical position whilst assuming a play bow. Aggressive or threatening dholes pucker their lips forward in a snarl and raise the hairs on their backs, as well as keep their tails horizontal or vertical. When afraid, they pull their lips back horizontally with their tails tucked and their ears flat against the skull.
Social and territorial behaviour

s rather than packs, as the latter term refers to a group of animals that always hunt together. In contrast, dhole clans frequently break into small packs of three to five animals, particularly during the spring season, as this is the optimal number for catching fawns. Dominant dholes are hard to identify, as they do not engage in dominance displays as wolves do, though other clan members will show submissive behaviour toward them. Intragroup fighting is rarely observed.

dens); complex cavernous earth dens with more than one entrance; simple cavernous dens excavated under or between rocks; and complex cavernous dens with several other dens in the vicinity, some of which are interconnected. Dens are typically located under dense scrub or on the banks of dry rivers or creeks. The entrance to a dhole den can be almost vertical, with a sharp turn three to four feet down. The tunnel opens into an antechamber, from which extends more than one passage. Some dens may have up to six entrances leading up to of interconnecting tunnels. These "cities" may be developed over many generations of dholes, and are shared by the clan females when raising young together. Like African wild dog

begins, the adults of the clan will regurgitate food for the pups until they are old enough to join in hunting. They remain at the den site for 70–80 days. By the age of six months, pups accompany the adults on hunts and will assist in killing large prey such as sambar by the age of eight months. Maximum longevity in captivity is 15–16 years.
Hunting behaviour
Before embarking on a hunt, clans go through elaborate prehunt social rituals involving nuzzling, body rubbing and homo- and heterosexual mounting. Dholes are primarily diurnal hunters, hunting in the early hours of the morning. They rarely hunt nocturnal

when hunting. Although not as fast as jackals and foxes, they can chase their prey for many hours. During a pursuit, one or more dholes may take over chasing their prey, while the rest of the pack keeps up at a steadier pace behind, taking over once the other group tires. Most chases are short, lasting only . When chasing fleet-footed prey, they run at a pace of . Dholes frequently drive their prey into water bodies, where the targeted animal's movements are hindered.
Once large prey is caught, one dhole will grab the prey's nose, while the rest of the pack pulls the animal down by the flanks and hindquarters. They do not use a killing bite to the throat. They occasionally blind their prey by attacking the eyes. Serow

Like African wild dogs, but unlike wolves, dholes are not known to attack people.[ Dholes eat fruit and vegetable matter more readily than other canids. In captivity, they eat various kinds of grasses, herbs and leaves, seemingly for pleasure rather than just when ill.] In summertime in the Tian Shan Mountains, dholes eat large quantities of mountain rhubarb. Although opportunistic, dholes have a seeming aversion to hunting cattle and their calves. Livestock predation by dholes has been a problem in Bhutan since the late 1990s, as domestic animals are often left outside to graze in the forest, sometimes for weeks at a time. Livestock stall-fed at night and grazed near homes are never attacked. Oxen are killed more often than cows, probably because they are given less protection.
Enemies and competitors
In some areas, dholes are wiktionary:sympatric, sympatric to tiger

s. Competition between these species is mostly avoided through differences in prey selection, although there is still substantial dietary overlap. Along with leopards, dholes typically target animals in the range (mean weights of for dhole and for leopard), while tigers selected for prey animals heavier than (but their mean prey weight was ). Also, other characteristics of the prey, such as sex, arboreality and aggressiveness, may play a role in prey selection. For example, dholes preferentially select male chital, whereas leopards kill both sexes more evenly (and tigers prefer larger prey altogether), dholes and tigers kill langurs rarely compared to leopards due to the leopards' greater arboreality, while leopards kill wild boar infrequently due to the inability of this relatively light predator to tackle aggressive prey of comparable weight.
Tigers are dangerous opponents for dholes, as they have sufficient strength to kill a dhole with a single paw strike. Dhole packs are smaller in areas with higher tiger densities due to tigers directly killing dholes and stealing kills they made. The kleptoparasitism causes dholes to prefer hunting smaller animals because they can eat more of a smaller carcass before a tiger arrives to steal it. Direct predation can lead to lower reproductive and recruitment rates, lower hunting success rates and less food for the pups when a helper is killed, and potentially pack destabilisation if one member of the breeding pair is killed.
Dhole packs may steal leopard kills, while leopards may kill dholes if they encounter them singly or in pairs.[ There are numerous records of leopards being treed by dholes.] Dholes were once thought to be a major factor in reducing Asiatic cheetah populations, though this is doubtful, as cheetahs live in open areas as opposed to forested areas favoured by dholes. Since leopards are smaller than tigers and are more likely to hunt dholes, dhole packs tend to react more aggressively toward them than they do towards tigers.
Dhole packs occasionally attack Asiatic black bears, snow leopards and sloth bears. When attacking bears, dholes will attempt to prevent them from seeking refuge in caves and lacerate their hindquarters.[
Although usually antagonistic toward wolves,] they may hunt and feed alongside one another. There is at least one record of a lone wolf associating with a pair of dholes in Debrigarh Wildlife Sanctuary, and two observations in Satpura Tiger Reserve. They infrequently associate in mixed groups with golden jackal

s. Domestic dogs may kill dholes, though they will feed alongside them on occasion.
Diseases and parasites
Dholes are vulnerable to a number of different diseases, particularly in areas where they are wiktionary:Sympatric, sympatric with other canid species. Infectious pathogens such as ''Toxocara canis'' are present in their faeces. They may suffer from rabies, canine distemper, mange, trypanosomiasis, canine parvovirus and endoparasites such as cestodes and roundworms.[
]
Threats
The dhole only rarely takes domestic livestock. Some ethnic groups like the Kuruba and Mon Khmer-speaking tribes will appropriate dhole kills; some Indian villagers welcome the dhole because of this appropriation of dhole kills. Dholes were persecuted throughout India for bounties until they were given protection by the Wildlife Protection Act of 1972. Methods used for dhole hunting included poisoning, snaring, shooting and clubbing at den sites. Native Indian people killed dholes primarily to protect livestock, while British sporthunters during the British Raj did so under the conviction that dholes were responsible for drops in Game (hunting), game populations. Persecution of dholes still occurs with varying degrees of intensity according to the region.[ Bounties paid for dholes used to be 25 rupees, though this was reduced to 20 in 1926 after the number of presented dhole carcasses became too numerous to maintain the established reward.] In Indochina, dholes suffer heavily from nonselective hunting techniques such as snaring.[
The fur trade does not pose a significant threat to dholes.][ The people of India do not eat dhole flesh and their fur is not considered overly valuable.] Due to their rarity, dholes were never harvested for their skins in large numbers in the Soviet Union and were sometimes accepted as dog or wolf pelts (being labeled as "half wolf" for the latter). The winter fur was prized by the Chinese, who bought dhole pelts in Ussuriysk during the late 1860s for a few silver rubles. In the early 20th century, dhole pelts reached eight rubles in Manchuria. In Semirechye, fur coats made from dhole skin were considered the warmest, but were very costly.
Conservation
In India, the dhole is protected under Schedule 2 of the Wildlife Protection Act, 1972. The creation of reserves under Project Tiger provided some protection for dhole populations sympatric with tigers. In 2014, the Indian government sanctioned its first dhole conservation breeding centre at the Indira Gandhi Zoological Park (IGZP) in Visakhapatnam. The dhole has been protected in Russia since 1974, though it is vulnerable to poison left out for wolves. In China, the animal is listed as a category II protected species under the Chinese wildlife protection act of 1988. In Cambodia, the dhole is protected from all hunting, while conservation laws in Vietnam limit extraction and utilisation.[
In 2016, the Korean company Sooam Biotech was reported to be attempting to clone the dhole using dogs as surrogate mothers to help conserve the species.]
In culture and literature
Three dhole-like animals are featured on the Coping (architecture), coping stone of the Bharhut stupa dating from 100 BC. They are shown waiting by a tree, with a woman or spirit trapped up it, a scene reminiscent of dholes treeing tigers. The animal's fearsome reputation in India is reflected by the number of pejorative names it possesses in Hindi, which variously translate as "red devil", "devil dog", "jungle devil", or "hound of Kali".
Leopold von Schrenck had trouble obtaining dhole specimens during his exploration of Amurland

, as the local Gilyaks greatly feared the species. This fear and superstition was not, however, shared by neighbouring Tungusic peoples. It was speculated that this differing attitude towards the dhole was due to the Tungusic people's more nomadic, hunter-gatherer lifestyle.
Dholes appear in Rudyard Kipling's ''Red Dog (Kipling short story), Red Dog'', where they are portrayed as aggressive and bloodthirsty animals which descend from the Deccan Plateau into the Seoni, Madhya Pradesh, Seeonee Hills inhabited by Mowgli and his adopted wolf pack to cause carnage among the jungle's denizens. They are described as living in packs numbering hundreds of individuals, and that even Shere Khan and Hathi make way for them when they descend into the jungle. The dholes are despised by the wolves because of their destructiveness, their habit of not living in dens and the hair between their toes. With Mowgli and Kaa's help, the Seeonee wolf pack manages to wipe out the dholes by leading them through bee hives and torrential waters before finishing off the rest in battle.
Japanese author Uchida Roan wrote (; A dog's tale) in 1901 as a Japanese nationalism, nationalistic critique of the declining popularity of indigenous dog breeds, which he asserted were descended from the dhole.
A fictional version of the dhole, imbued with supernatural abilities, appears in the season 6 episode of TV series ''The X-Files'', titled "Alpha (The X-Files), Alpha".
In China, the dhole were widely known throughout history and mythology. One notable legendary creature is the Nine sons of the dragon, Yazi (), which was believed to be a creature that was part-dhole part-dragon. In modern times, however, the Chinese word for dhole () is often confused with 'jackal' or 'wolf', resulting in many confusions and mistranslations of dholes as jackals or wolves.
Dholes also appear as enemies in the video game ''Far Cry 4'', alongside other predators such as the Bengal tiger, honey badger, snow leopard, clouded leopard, Tibetan wolf and Asian black bear. They can be found hunting the player and other non-player character, NPCs across the map, but are easily killed, being one of the weakest enemies in the game. They once again appear in the video game ''Far Cry Primal'', where they play similar roles as their counterparts in the previous game, but can now also be tamed and used in combat by Takkar, the main protagonist of the game.
