No, true protection dogs are not aggressive.
Protection dogs are chosen for their temperaments and personalities and we do not select dogs for training who show any sign of aggression. A protection dog is calm, confident and expertly trained to resolve threats. A true protection dog has thousands of training hours under their belt of how to behave perfectly and how to protect their owners in case of threat. Protection dogs are assertive, which means they sit and observe and do not get riled up at any little thing. They save their energy for true threats.
Aggression is generally a personality and temperament issue. We do not select dogs for protection work who show signs of aggression. Aggression in dogs generally comes from fear and fearful dogs do not make quality protection dogs. All of our dogs are chosen for their confidence, sound temperaments and trainability so you know that you are getting a great dog with a fantastic personality.
