Valid Protection Strategy Against Islamist?

As you all may already know: Islam states that Dogs (Or Black Dogs) are the Devil. I personally have experienced many times how afraid Muslims and Islamists are of Dogs (regardless of their color) or black cats.

Do you think it is wise as an ex moose to have a black dog not just because dogs are awesome and cute and cool and reliable and generally great supporters but also because it could make Islamist knife stabbers think thrice before attacking me?
