Executive Protection Dogs are for defense, not offense. Many guard dog owners opt to let a professional dog trainer train their new pooch. If the dog shows signs of aggression while out in public, it will need to be socialized in a calming atmosphere. Dogs that show new need for chasing are perfect as protection dogs because they are obedient. Avoid purchasing or adopting a herder dog, since they have an incredible instinct to chase.
