4. For the paranoid: Rottweiler
If you hope to get a dog that’s willing and able to protect you and those you care about, is built like a tank and will gladly take on Satan and a legion of demons to protect you, the Rottweiler may be the one for you. These dogs tend to be wary of strangers and can take some time for people they do not know to earn their trust. For those that they do know and love, they will stay by their side faithfully to the bitter end.
