A chocolate Lab is a Labrador Retriever with a brown coat, one of the three colors the breed standard accepts. The breed traces back to Newfoundland's St. John's water dogs and was developed in Britain as a gun dog, which explains the water-resistant double coat, the thick otter tail and the love of fetch. Adults usually weigh 55 to 80 pounds and shed all year, with heavier seasons in spring and fall.
Chocolates share the Lab's sociable, eager-to-please nature, though behavior varies from dog to dog and coat color doesn't predict it. A UK study found chocolates lived about a year and a half less on average and had more ear and skin problems, so ear care and a lean weight matter. Mansfield's cold, snowy winters suit the coat well.
