Chocolate labs tend to live shorter lives than their yellow and black counterparts, and they tend to have a high rate of skin and ear disease, reported Live Science, citing a new study by an international group of researchers.
The scientists, who are part of a research project called VetCompass, have studied about 2,000 labs from a larger database containing information on more than 30,000 people of the breed.
