In addition to “Andean double-nosed tiger hound,” there are two pointer (really HPR) breeds that have double noses: the Navarro Pointer and the çatalburun or Turkish pointer. German short-hairs and some Porguese pointrs have the double-nosed characteristic, probably as the result of having ancestry from the Navarro pointer. I am not as willing to suggest, as the BBC report does, that the Bolivian jaguar hunting dog are descended from any sort of European breed. It seems to me that they are very likely to be an indigeneous Bolivian creation. Because all Latin American dogs have a very high amount of European dog in them, though, it is possible that the some Navarro Pointer blood got into the local jaguar dogs.
The çatalburun is native only to the Tarsus region. It is virtually unknown outside of Turkey. It is possible that this is home to the original mutation of split-nosed dogs in the Old World. The Spanish and Portuguese were major rivals of the Ottoman Empire during the fifteen and sixteenth centuries. It is possible that they obtained these dogs from Turkey. It is also possible that the origins of the mutation is Iberia, rather than Turkey, and the dogs eventually wound up in Turkish hands. I have yet to find really good historical records on either the Iberian split-nosed dogs or their Turkish counterparts.
The Navarro pointer, Pachon Navarro, or Perdiguero Navarro is another rare breed with that same unusual nose. Unlike the çatalburun, the dogs don’t always have a double nose, but they very often do. This breed is one of two breeds that was referred to as the Spanish pointer. (The other one is the more widely known Perdiguero de Burgos, which is the ancestor of both the German short-hair and the English pointer.)
