Often folks thinking about sd at home forget one of the best aids to situational awareness and deterance: a dog.

Doesn't have to be attack trained, or even mean.

A dog is much more aware of what's going on around it than most folks. A dog will alert you to events and strangers long before you can detect them. Dogs are always in 'condition yellow'.

Dogs are also great deterants. Most BG's would rather tackle a home or person without a dog than one with a dog.

Don't overlook the added security a dog can provide.
