Shetland sheepdogs, also known as shelties, bond with their owners in a special way. They’re loyal to an extreme, willing to do anything to please their owners. Unlike Rottweilers, shelties are unlikely to resort to destructive behavior if they’re under-stimulated, so basic obedience training will suffice.
They’re plenty smart enough to pick up new skills, however, and their light, agile frames are ideal for agility training.
