Here is a small selection of training videos featuring Darkvakia dogs.

A protection dog should be conditioned and trained
to protect in any environment.
The dog should always focus on the man,
not merely on the big padded sleeve he is wearing on his arm.

Controlled civil aggression: Bertha of Darkvakia

Passive attack: The threat in this case is in the letter being delivered by the pretty lady.
The objective is to demonstrate that though the dog sees no threat.
He still reacts instantly to his handler’s command to engage – an insightful test.
