The beagle is a small to medium-sized breed of dog known for its keen sense of smell and friendly nature. Originally bred for hunting, beagles are often used in detection work due to their strong tracking instincts. They have a short coat, typically in a mix of colors like tri-color (black, white, and brown) or lemon (light tan and white). Beagles are social animals that thrive in family environments. They are known for their playful and curious personalities, making them great companions. Regular exercise and mental stimulation are important for beagles to keep them happy and healthy, as they can become bored easily.
