The dog is a domesticated mammal known for its loyalty, intelligence, and companionship. Descended from wolves, dogs come in a wide variety of breeds, sizes, and temperaments. They are social animals, often kept as pets, working animals, or service animals. Dogs communicate through barking, body language, and facial expressions. Their keen senses, especially smell and hearing, make them valuable in roles such as hunting, herding, guarding, and assisting people with disabilities.
