Very high energy and very attached to its handler. Best for experienced, active owners who enjoy daily structured work.

Versatile and trainable, with a long history in police, military and family roles. Lines differ, so ask which one you are looking at.

Powerful, steady and self-assured. Often calmer than herding breeds, and best with confident, consistent handling.

Lean, quick and devoted. It tends to want constant contact with its person and dislikes long isolation.

Start with your daily routine and living space, then your experience, then the breed.
Ask for health testing records for the parents and the dog.
Meet the individual dog. Two dogs of one breed can be very different.

Is a bigger dog a better protector?

Not necessarily. Control, stability and training matter more than size, and a very large dog can be harder to handle and to insure.

It is uncommon. Professionals usually want known genetics and a proven temperament for this work.
