Developed in mid-1800s England as a gamekeeper's retriever for land and water, the Flat-Coated Retriever was once Britain's favorite retriever before Labradors and Goldens overtook it. Its numbers fell dangerously low around the two world wars, and careful work from the 1960s rebuilt the breed. Flat-Coats have a long, one-piece head unique among retrievers and a glossy, flat-lying coat in solid black or liver, with feathering on the legs and tail.
Often called the Peter Pan of dogs, many Flat-Coats keep a puppyish, tail-wagging exuberance well into old age. They tend to be cheerful, people-focused and eager to please, which makes training rewarding, but they need lots of exercise and dislike long hours alone. Prospective adopters should also understand the breed's unusually high cancer risk, which shortens many lives.
