The University of Sydney studied one of the most popular breeds in the world, Labradors. After analyzing more than 33,000 veterinary reports, the research team discovered that chocolate-colored Labradors live less than black or yellow ones . They also found that chocolates have a higher risk of ear and skin problems . "The relationships between coat color and disease may reflect an inadvertent consequence of the reproduction of certain pigmentations," Paul McGreevey, leader of the research, told Fox News . The most common cause of death among Chocolate Labradors was musculoskeletal disorders and cancers, according to Professor McGreevey.
The researchers would like to expand the evidence for possible links between pigmentation and health in a broader range of dog breeds. "The results can alert owners to potential health problems and inform breed-specific wellness checks," Paul McGreevey, lead of the investigation, told Fox News .
