A chocolate Lab is a Labrador Retriever in the breed's brown coat, with a brown nose, brown eye rims and brown or hazel eyes. The sturdy build, otter tail and dense double coat come from retrieving game in cold water, which is about as far from the desert as a coat can get. That coat sheds year-round, so brown hair on floors and furniture is part of life with one.
Most chocolate Labs are friendly, food-driven and eager to please, but dogs vary, and color doesn't set personality. One research finding is worth knowing: a large UK study found chocolates lived about a year and a half less on average and had more ear and skin problems. That's a good reason to budget for routine vet care and keep a young adult lean and active.
