The Canaan Dog is sometimes mistakenly believed to be a pariah dog which roams throughout the Middle East, however this is incorrect. The Canaan Dog is a true breed which has survived in the desert for more than 2000 years. In the 1930s the Israelis began a program of re-domestication of these dogs, recognizing their potential as guard dogs to guard their settlements . Their history as a desert breed has contributed strength and endurance to the genetic makeup, to say nothing of the fact that they are relatively disease free. Their bodies have developed in much the same way as the Arabian Horse, strong lungs and resistance to extremes of weather are part of their heritage.
