Working Kelpies are medium-sized dogs. Males typically weigh between 30 to 50 pounds, while females usually weigh around 25 to 45 pounds. They stand about 17 to 20 inches tall at the shoulder.

Kelpies are known for their intelligent, energetic, and driven nature. They are highly trainable and excel in various tasks, making them ideal working dogs. They are also known for their loyalty and strong herding instincts. While Kelpies are friendly and affectionate with their families, they can be reserved or cautious around strangers, which can make them good watchdogs.

The Working Kelpie has a short, weather-resistant coat that is smooth and easy to manage. Their coat can come in various colors, including black, red, blue, chocolate, or fawn, often with tan markings. Regular grooming is recommended to keep their coat healthy and to remove loose hair.

Working Kelpies thrive in active environments and require daily mental and physical stimulation. They are best suited for homes where they can engage in exercises that match their high energy levels. Rural or suburban settings are ideal, but they can adapt to urban living if provided ample activity and companionship.

Kelpies enjoy a wide range of activities that involve physical and mental challenges. They excel in herding trials, obedience training, agility, and flyball. Regular outdoor activities such as running, hiking, and playing fetch are essential for keeping them happy and healthy. Additionally, providing them with tasks, whether official working duties or playful games, helps to satisfy their instinctual need for work.
