A chocolate Lab is a Labrador Retriever with a brown coat, one of three colors the breed accepts alongside black and yellow. Chocolates have the Lab's sturdy build, otter tail and dense, weather-resistant double coat, plus a brown nose and brown or hazel eyes. Most weigh 55 to 80 pounds and stand 21 to 25 inches tall.
Temperament doesn't change with color. Many chocolate Labs are friendly, food-driven and eager to work with people, so they do best with company, training and measured meals. They shed year-round and more in spring and fall. A large UK study found chocolates lived about a year and a half less on average and had more ear and skin problems, so a veterinarian can help you plan preventive care.
