Dogs can bark, bite, and poop.
They cannot, however, shoot back at an intruder.
And guns can't watch your back while you are sleeping. I have heard from a few well-armed people who woke up with a gun in their face.
Lose that fancy named sissy dog and get yourself a Glock. Beware of the armed homeowner.
If you can get past my 120 pound "sissy dog" then you will certainly meet a homeowner who both already knows you are there even if he was asleep when you broke in (perhaps from the screams you gave when you lost your gluteus maximus) and is well-prepared to greet you. No one should be under the impression that getting past that big furry teddy bear means their problems are over.
The crime rate variance, vis a vis canine concentration, would be negligible in this fellow's opinion.
Probably true. Most crime happens outside the home and 100-pound-plus dogs are not really good for concealed carry.
