My dog is not going to be liable in anything, because I personally trained him. I am qualified and have worked with the police. I trained my last dog as an attack dog, but again, done correctly, by a professional, I can stop him at any time. Little kids would pounce on him on a reg. basis, with no aggression.
The police person above, I don't know if you are an actual trainer or handler (to the people that don't know, a lot of K-9's are trained before hand and then are put with their police person "handler." But he/she makes sense...
Again, I just didn't do this on my own, I am a professional and no, if someone entered my home to do me harm, you are dang straight that I would have my dog attack until I pulled my weapon.
I don't leave my dog unattended and I am in full control, plus my dog has actual training, real training and is not out to bite people to bite. I have commmands in place.
Oh, and by the way, I am female and I would shoot to kill.....
These are certain measures that one must take in order to train an "attack dog" properly. If done wrong, then yes, the owner can get in trouble. But not me.... because, again, if someone breaks into my home to cause harm....well that's too bad. I could also have a huge lists of animal expert witnesses to have my back, plus police.
