The Old Croatian Sighthound, regionally known as the hrt, is a breed of dog from Croatia. Originally developed as a sighthound, the greyhound-like breed was almost exterminated during Croatia's time as part of Yugoslavia; however, its continued existence was confirmed in December 2008.This recent (Bauer & Lemo, December 2008) report containing a record of a preserved nucleus of a regional Old World sighthound, the hrt or Old Croatian sighthound, is a notable cynological and veterinary contribution to sighthound history. It is one more confirmation of the mechanism behind the extinction of sighthound varieties, where the loss of "aristocratic", landed hunting rights (pursued mainly by horse, and hound) gave place to "universal", licensed hunting rights (pursued mainly on foot, by gun) which tended to literally outlaw sighthounds. Sighthounds, which by definition require large open tracts of land, became an object of suspected poaching, and were often actively persecuted. Consequently the regional and national varieties, which for ages had been prolific across Europe, were eradicated or allowed to die out. The Chort, Magyar Agar and Chart, for example escaped this fate, the Frisian sighthound did not. Where national breed and Kennel Clubs actively encouraged sighthound studbooks, and where a strong coursing culture was present sighthounds such as the Galgo survived. In some cases, as with the latter, and as Bauer and Lemo report in connection with the hrt, regional sighthound identity could be compromised by crosses to Greyhounds or other breeds.
