The Labrador Retriever, or just Labrador, is a large breed of retriever-gun dog. The Labrador is the most popular breed of dog in Canada, the United Kingdom, and the United States.

A favourite disability assistance breed in many countries, Labradors are frequently trained to aid those with blindness or autism, act as a therapy dog, or perform screening and detection work for law enforcement and other official agencies.

The breed is best known for their obedience, loyalty, and playful composure. They are known to be very docile.

Additionally, they are prized as sporting and hunting dogs. In the 1830s, the 10th Earl of Home and his nephews had imported progenitors of the breed from Newfoundland to Europe for use as gundogs.

Another early advocate of these Newfoundland dogs, or Labrador Retrievers as they later became known, was the 2nd Earl of Malmesbury who bred them for their expertise in waterfowling.

Labradors are medium-large, with males typically weighing 65–80 lb (29–36 kg) and females 55–70 lb (25–32 kg). The majority of the characteristics of this breed, with the exception of colour, are the result of breeding to produce a working retriever.
