No dogs for us either. A dog would probably outlive us too. I have a .22 and a 410 with critical defense slugs and other ammo. Most of the people that live in our area have guns and every so often we hear them shooting. Not long ago a woman from Virginia bought 10 acres behind us. She had a German Schnauzer. Not long ago she let it out to do it's business one night and it ventured too far from her house and some coyotes seriously injured it and it died. She was concerned about hearing the gunfire around sometimes and we told he to be grateful she hears it and that we have guns and maybe she should invest in one and learn how to shoot it. Hubby gave her a can of pepper spray, the same as the police use, It actually sprays pretty far and she was happy with that for now. I mentioned to her about a game camera.
while the .410 will work great with the right load, the .22 (i assume you're referring to .22LR?) is not thenbest defensive round. it's better than nothing, but don't count on it to save your life.
every sane adult in america should be armed to the teeth all the time, and they should practice weekly, if not daily.
an armed society is a polite society. period.
there's a reason mass shootings only happen in gun-free zones.
