Did you know? Those tan markings above the eyes often seen in Rottweilers and Dobermans and other tan-pointed dogs, are known as "pips." According to Stanley Coren, dogs with such eye markings, the “four-eyed dogs," were once thought to have superior physic abilities. The Tibetan mastiff, which also has these markings, was believed to foresee evil as much as three days in advance.
