Border Collies are medium-sized dogs. Typically, they weigh between 30 to 45 pounds and stand about 18 to 22 inches tall at the shoulder. Males generally tend to be larger than females.

Border Collies are known for their high intelligence, energy levels, and strong work ethic. They are highly trainable and often eager to please, making them excellent companions for active families. They are also known to be affectionate, loyal, and often form strong bonds with their owners. However, they can be reserved with strangers.

Border Collies have a double coat that can be either smooth or rough. The rough coat is longer and more feathered, while the smooth coat is shorter and denser. Their fur comes in a variety of colors, including black and white, red and white, blue, and merle. Regular grooming is necessary, especially during shedding seasons.

Border Collies thrive in active environments where they can work or participate in physical activities. They require plenty of mental and physical stimulation to prevent boredom, which can lead to destructive behaviors. Historically as herding dogs, they do best in homes where their skills can be utilized, such as with activities that require focus and problem-solving.

Border Collies enjoy a variety of activities, including:

• Herding trials and competitions
• Agility training
• Obedience competitions
• Fetch and frisbee games
• Long walks, runs, or hiking
• Dog sports such as flyball and disc dog events

Engaging in these activities helps satisfy their high energy needs and keeps them mentally stimulated. Proper training and socialization from an early age are also essential for a well-rounded Border Collie.
