First, you need to train your dogs to come to you when called and to stay with you. If you are the target in a home invasion or burglary, etc. your dogs are fine for setting the alarm but they need to get out of the way once the alarm has been "barked". I have four dogs, ranging in size from fifty pounds to 140 pounds. In the daytime, they have the fenced yard to watch over with two doggie doors into the house. At nite, we "pull in the perimeter" and lock the dogs inside the house with us. They are not attack dogs but their alert mode is very intimidating. When I "tell" them to get-outa-da-way, they move back.
Second, assorted types of pepper sprays work fine most of the time on most people....with Most being the key word. They're fine for police officers to give them other options besides lethal force but they always have a Plan B in case Plan A (Pepper spray) doesn't work. I once used a whole can of law enforcement (It's my other job!) type pepper spray on a bad guy and it didn't faze him at all. That same guy was Tased by my partner. (Plan B) He pulled the wires out and kept coming. We finally got him under control by piling lots of people on him. (Plan C)
In a home invasion or drug crazed attacker scenario, you probably wont have lot's of freinds there to help you so Plan C is out. In a closed environment, pepper spray will affect you almost as much as the bad guy. A Taser works most of the time, if you get both barbs into him and if he doesn't manage to pull the wires out. However, what if there's more than one bad guy? A Taser has to be reloaded for the next "shot" and once you drop the empty cartridge, you loose control over the first guy....who's now going to be really upset because you shot two little barbed arrows into him!
A firearm really is the best defense for a home type scenario. The type of firearm is up to you. In my home, my Wife and I both have handguns close by the bedside but they're just to get us to the pump shotguns....which are just to get us to the gun safe where the real fire-power is.
I often get asked "what's the best defense for me in my home"? My answer is always the same: A little dog for the alarm and a big gun for the defense.
Now having said that, I have to add one thing. I often get asked about the size of firearm to get for home defense. The answer is: The biggest one that you can shoot well. My Mom was getting to old and frail for the massive revolver that she usually depended on but she liked the intimidation factor of the huge muzzle bore. She started carrying a big .22 caliber revolver but it had a counter bored muzzle. From the front, it looked like a .45. It was only a .22 but she fired Vipers out of it and could pop an eyeball on the move at 25 paces with it. Keep yer powder dry, Mac.
