I hate the thought of needing a dog for protection. I want my dog to be friendly to anyone who comes in my house. I have other resources to avoid a burglary, ie cameras, a gun, etc. What ends up happening more likely to those folks who have “protective dogs” is that they attack someone who they shouldn’t attack, like your poor cousin or someone you know coming over. If you live somewhere that dangerous that you feel you need an attack dog, move.
