Border Collie Sheepdogs are courageous, self-confident, and fearless. Sheepdogs learn commands quickly, are loyal and highly intelligent. They are also extremely reliable and even put themselves in danger for others. All this makes them popular police and family dogs.
Unfortunately, much experimentation has been done with this breed to perfect their intelligence and endurance. As a result, sheepdogs are genetically predisposed to degenerative diseases, such as hip dysplasia.
