Murcian Ratter (Ratonero murciano) or Huerta Ratter (Ratonero murciano de huerta) is a Spanish breed of dog originating from Region of Murcia. While the region and its economic activities developed, the numbers of the breed started to decrease. In the 20th century, it was already isolated to very small regions of Murcia. Its breeding was still continued in Bajo Guadalentín and Alto Guadalentín and the highest number of individuals was found in the municipality of Lorca. It was still appreciated in local factories and mills as an efficient ratter. In other municipalities of the region, it was used as a protector of rabbits. A typical characteristic of the breed is its longevity. For example, a female named Estrella has achieved the age of 23 years. Usually the average life expectancy is 14 years or more.
