Character and temperament

They love human attention and can be calm and tolerant of children. A loyal dog that is very protective and needs to be socialised from an early age. It is recommended that introductions to strangers are done by people who the dog trust. An experienced handler is needed for training due to their willful nature. It is not a difficult dog to train but does need a handler that can assert his authority. A devoted guard dog with a good natured temperment.


Created in the late 1800's to catch poachers. They were not trained to kill but to overpower their target. Since then they have been used in the Army and as a police dog and hunting/guarding.
