This is the single most important thing to know about the breed: Flat-Coated Retrievers have an unusually high rate of histiocytic sarcoma, an aggressive cancer that affects roughly 20% of the breed with near-uniform fatality — a genuine, well-documented breed-specific risk that's the subject of ongoing genetic research. The breed is also predisposed to hip dysplasia and glaucoma, typically appearing around age 5-6.
A quality diet in measured portions; standard weight management applies, though periodic health screening matters more for this breed than diet given the cancer risk.
The moderately long, flat-lying coat needs regular brushing, with feathering on the legs and tail needing extra attention to prevent matting.
Eager to please and highly trainable, Flat-Coats do well with positive reinforcement and need real daily exercise to match their genuinely high energy level, which persists longer into adulthood than in many other retriever breeds.
The Flat-Coated Retriever was developed in 19th-century Britain as a versatile retrieving gundog, one of the first two retriever breeds recognized alongside the Curly-Coated Retriever. Sometimes called the "ebony retriever" for its sleek black coat, the breed can be mistaken at a glance for a black Golden Retriever, though it's a genuinely distinct breed with its own long, low-set head shape.
Flat-Coats are known for a puppy-like exuberance that persists well into adulthood — genuinely cheerful, energetic, and affectionate, a temperament the Flat-Coated Retriever Society of America describes as central to the breed's charm.
