Labrador retriever

The Labrador Retriever would have to be one of the most familiar breeds of dog to many. Labradors are noted for their friendliness, intelligence (though they don't often show it) and their obedience. Because of these traits, they are often trained to be assistance dogs[?], such as service dogs or guide dogs.

Labradors are relatively large dogs and they are either black, brown or yellow in colour.
