The possible earliest written use of the word in English occurred in 1808 by soldier Thomas Williamson, who encountered the animal in Ramghur district.
The Merriam-Webster Dictionary theorises that it may have come from the tōḷa ('wolf'). ==Taxonomy and evolution== Canis alpinus was the binomial name proposed by Peter Simon Pallas in 1811, who described its range as encompassing the upper levels of Udskoi Ostrog in Amurland, towards the eastern side and in the region of the upper Lena River, around the Yenisei River and occasionally crossing into China.
During the early Middle Pleistocene there arose both Canis majori stehlini that was the size of a large wolf, and the early dhole Canis alpinus Pallas 1811 which first appeared at Hundsheim and Mosbach in Germany.
In 1827, Charles Hamilton Smith claimed that it was derived from a language spoken in 'various parts of the East'. Two years later, Smith connected this word with deli 'mad, crazy', and erroneously compared the Turkish word with dol and dol (cfr.
This northern Russian range reported by Pallas during the 18th and 19th centuries is "considerably north" of where this species occurs today. Canis primaevus was a name proposed by Brian Houghton Hodgson in 1833 who thought that the dhole is a primitive Canis form and the progenitor of the domestic dog.
The paleontologist Bjorn Kurten wrote in his 1968 book Pleistocene Mammals of Europe that the primitive dhole Canis majori Del Campana 1913 - the remains of which have been found in Villafranchian era Valdarno, Italy and in China - was almost indistinguishable from genus Canis.
Hodgson later took note of the dhole's physical distinctiveness from the genus Canis and proposed the genus Cuon. The first study on the origins of the species was conducted by paleontologist Erich Thenius, who concluded in 1955 that the dhole was a post-Pleistocene descendant of a golden jackal-like ancestor.

This closeness to Canis may have been confirmed in a menagerie in Madras, where according to zoologist Reginald Pocock there is a record of a dhole interbred with a golden jackal. === Admixture with the African wild dog === In 2018, whole genome sequencing was used to compare all members (apart from the black-backed and side-striped jackals) of the genus Canis, along with the dhole and the African wild dog (Lycaon pictus).
