Additional information (Wiki): The Flat-Coated Retriever is a gundog breed from the United Kingdom. It was developed as a retriever on both land and in the water. Flat-coats make exceptional family companions, bonding very closely with all members of the family. Compared with other sporting breeds, Flat-coats have a relatively low activity level indoors, but outdoors can play, run and retrieve tirelessly. Flat-coats given too little exercise, companionship and mental stimulation, however, can become overly active or destructive indoors, especially if left alone for extended periods of time. They are wonderful with older children but may be too exuberant for very small children. Early obedience training and socialisation are highly recommended. The well-socialised and well-trained Flat-coat is an optimistic, enthusiastic dog with a constantly wagging tail who is a friend to all.

The Flat-coat’s personality is described as outgoing, devoted, and friendly, an ideal companion with a strong bond to its owner and family. It is a versatile hunting dog, retrieving well on land or in the water, flushing upland game, marking downed birds, and generally performing all the tasks expected of a multi-purpose gundog. Although not as well known and much less popular than the Labrador and Golden Retrievers, it has benefited from that lack of popularity by enjoying more careful breeding and better maintenance of its working ability.
Flat-coats love water

Flat-coats love to please, but may be slightly more difficult to train than Golden Retrievers and Labradors. They are easily bored with repetitive training techniques and can exhibit a streak of willfulness at times. For this reason, it is best to make training sessions fun, varied, and relatively short for the dog. Flat-coats are very sensitive and respond best to positive reinforcement. They cannot tolerate harsh handling or corrections.

Flat-coats are known for having a sunny optimism and a tail that is always wagging. They are capable of getting along well with cats, other dogs, small pets, and strangers. However, due to their exuberant nature, they may tend to knock over very small children. Socialization and obedience training are highly recommended. Flat-coats are known to demonstrate their affectionate natures by frequently kissing their human friends. They also display an unusual habit with their canine friends: the "flat-coat kiss", where the dogs lick each others mouths as a form of greeting. Since they are inclined to be friendly to all, they make only adequate watchdogs to give warning.
