I have the alarm company stickers on my windows and doors with no mention of fire arms. I also have a Doberman that is protection trained and will attack anyone entering my house when I am not home. A friend of mine doubted he would attack him because he knows him. LOL foolish man he is. He got bitten
I had beware of dog signs on my doors and my insurance man told me to take them down as it was an admission that I had an aggressive dog. If the dog did bite someone and they sued me they would use the signs against me in court.
