The Alaunt is an extinct breed of dog, with the original breed having existed in central Asia and Europe from ancient times through the 17th century.
 The Alaunt breed had three distinct phenotypes: Alaunt Veantre, Alaunt Boucherie and the Alaunt Gentile.
 They all were large, short coated dogs of varying head-types.
 The former two resembled the molosser type dogs much like the present-day Dogo Argentino or like the Caucasian Shepherd Dog except with short hair and a mesocephalic head which made them excellent large-game hunters.
 The Alaunt was originally bred by the Alani tribes, the nomads of Indo-European Sarmatian ancestry who spoke an Iranian language.
 The Alans were known as superb warriors, herdsmen, and breeders of horses and dogs.
 The Alans bred their dogs for work and developed different strains within the breed for specific duties.
 The breed was further developed in Spain, France, Germany, England, and in Italy.
