Pachon Navarro

Dog

The Pachon Navarro is a Spanish hunting dog (also known as: Old Spanish Pointer; Perdiguero Navarro; Navarro Pointer; and, Pachon De Victoria), has the unusual feature of a split or double nose. It is believed that this unusual nose gives this dog extra sensitivity to smells, a primary reason it was chosen as a hunting dog.
