Based on your explanation for why and what you are training your puppy I would strongly ask you to reconsider at this time and age. In my experience, personal protection training (home invasion, carjacking etc.) is not a puppy's game. It is a very serious endeavor. Obedience training is a strong prerequisite for this type of training, not just sit and down but let me drop the leash and your dog can obey you from a distance without fail. At 11 weeks a 2 min. distracted stay is an accomplishment. I am a strong believer that a dog trained to bite without a strong obedience background is a hazard and a danger. I am very surprised to hear a trainer who feels an 11 week old can be ready for protection in 4 months. I will jump off my soap box now, sorry to be so strong in my wording, I like to only reply on the positive but take it as honest reply to your questions.
