This tough, hardy breed of retriever is a great choice as a family pet. They are playful, easy to train, and naturally obedient. Labrador Retrievers do require regular amounts of daily exercise and are prone to obesity. As a pet, they can be demanding of attention and are best suited in a home where they can have a daily workout. They like water and have a unique otter-like tail, which they use like a rudder when they swim.
