should i get my dog trained in guard dog school

Schutzhund, or as you so lightly call it "guard dogs" are not for the inexperienced!!! They are not the average dog, for the average owner. In order for a dog to become a guard dog, you need to spend TONs of time and resources for him to be that way. I have personal experience with dogs trained in Schutzhund, and I cant EVER imagine what would happen if Anya (the dog), who has the power and potential to seriously injure someone, was placed in the wrong hands. Having a guard dog, without proper training, can be a huge liability to you. Lets say that "Guard Dog" goes out and bites a 5 year old girl in the face- Whos the one to blame? and Who is the one to get sued. Um.... You!?! You could lose everything you own. Sure you might think 'Oh well my dog will never get out and hurt someone. I wont let it' ... Even Anya gets away from me sometimes, but I trust her enough that she wont go very far and I depend on her recall to bring her back to me. Most dogs I see, dont have that kind of dicipline.
