Study Links Dog's Coat Color With Longevity

A new report is linking the color of their coasts to longevity.  Research looked at the health outcomes of 33,000 veterinary patient records of one of the world's most popular dog breeds, Labradors. What they found was chocolate labs live significantly shorter lives than their black and yellow cousins. The average age of non-chocolate labs was 12.1 years, more than 10% longer than chocolate ones at 10.7 years. It also found chocolate labs were twice as likely to suffer from ear infections and four times as likely to experience skin problems. The relationships between coat color and disease may reflect an inadvertent consequence of breeding certain pigmentations. Because chocolate color is recessive in dogs, the gene for this color must be present in both parents for their puppies to be chocolate. Breeders targeting this color may therefore be more likely to breed only Labradors carrying the chocolate coat gene resulting in a reduced gene pool that may include a higher proportion of genes that cause ear and skin conditions. The most common causes of death for chocolate labs were musculoskeletal disorders and cancers. Researchers now want to explore any possible pigmentation-health links in a broader range of canine breeds.
