I keep a loaded 12 gauge and a loaded mag and rifle within easy reach as a matter of home security so yes the 15 seconds to grab it wouldn’t be an issue for me. Let say you didn’t have a weapon within imediate access (ie locked in a safe) then your theory holds. Like cap crew stated your a good sized dude, I’m about 160 so it’s a little different. Also your not pulling a distinction between your animal or the ones you love and the agressor. Not to sound like a dick, but I hold those I care about in a higher regard then some dog attacking them.
