Curly-coated retriever is a dog trained to bring back game that has been shot. It gets its name from its black or liver-colored coat, which is a mass of thick, tight curls. This coat keeps the dog from getting chilled while swimming. The dog will work in cold water for a long time. It stands about 26 inches (66 centimeters) high at the shoulder and weighs from 50 to 80 pounds (23 to 36 kilograms). A curly-coated retriever is fairly easy to train, and makes a good watchdog.
