A canine can be just as good, if not better, than an electronic home security system. However, a canine should not be relied upon because after all they are an animal and can be coerced away, or constrained, from protecting the home. Have you ever seen those hollywood heist movies where the professional criminal will use food to stop the dog from barking? Well, it is true… a dog can be manipulated in to trusting a stranger with these type of simple methods. Also, make sure to check with insurance companies because certain breeds of canines can be considered a liability. Also, you are putting a canine in harms way if they are used as a home security unit. A burglar can poison an animal, shoot an animal, or do something horrible to stop it from protecting the home.
