While most people consider domesticated dogs to be friendly and easygoing, the reality is that there are a number of dog breeds that have been blacklisted by a wide range of insurance companies. Certain breeds of dog are more dangerous than others and the type of breed that you choose could have an effect on your ability to obtain insurance for your home.

Their size and aggression makes them far too much of a liability.
