A chocolate Lab is a Labrador Retriever in the liver-brown coat, one of three colors the breed standard accepts. The breed traces back to Newfoundland water dogs and was developed in Britain as a gun dog, which explains the dense, weather-resistant double coat, the otter tail and the love of water. Chocolates have brown noses and eye rims, and adults usually weigh 55 to 80 pounds.
Color doesn't set personality. Most chocolate Labs are outgoing, eager to please and motivated by food, though young ones can be bouncy and mouthy, and dogs from field lines tend to need more work than show-line dogs. Shedding is moderate to heavy and continues all year, so weekly brushing helps. A large UK study found chocolates lived somewhat shorter lives on average, which makes routine vet care worth prioritizing.
