Labrador Retrievers descend from the St. John's water dogs of Newfoundland, which British sportsmen shaped into gun dogs that retrieve from land and water. The dense, water-resistant double coat, thick otter tail and webbed toes all come from that work. Labs come in black, yellow and chocolate, and field-bred dogs tend to be leaner and higher-drive than show-bred ones.
In Bayamon, the double coat is the part to plan around. With no real cold season, a Lab may shed steadily through the year, so expect hair on floors and furniture and a dog that needs shade, water and a cool indoor spot between outings. Labs are sociable and food-motivated, which makes training easier but means portions need watching. Adolescence can be bouncy and last until two or three years old, and each Lab's energy level and history vary.
