The Labrador Retriever is a medium to large breed known for its friendly and outgoing nature. It has a short, dense water-resistant coat, usually in black, yellow, or chocolate. Labradors are highly intelligent, making them excellent working dogs, often used in search and rescue, therapy, and as guide dogs. They are energetic and require regular exercise, thriving in active households. Their keen sense of smell and trainability also make them popular in hunting and detection roles.

Labrador Retrievers originated in Newfoundland and Labrador, Canada. However, as a domesticated breed, they do not have a 'native region' in the wild sense like wild species do.

Labrador Retrievers thrive in a variety of environments due to their adaptability, but they originally lived in cold, maritime climates. They were originally bred for retrieving in cold waters, which indicates their tolerance for colder temperatures. The breed is well-suited for both rural and urban settings, provided they receive adequate exercise.

As a domesticated breed, Labrador Retrievers do not occupy an ecological niche in the wild. Their role as a working dog includes hunting, retrieving, and assisting in various tasks such as search and rescue, therapy, and as guide dogs for the visually impaired. They are known for their versatility and adaptability to various roles.
