Our Maltese sleeps on the foot of our bed facing out. She misses nothing. She is fearless and has no idea she weighs only 8 pounds.
She won’t stop anyone using brute force, but they’ll know they are under attack and have their hands full while I chamber a round.
I know what you mean. My mom had Maltese and some were truly fearless. But I need big dogs due to mountain lion presence. Two winters ago the deer population declined and the mountain lions began preying on dogs. I recall that 12 dogs were lost in the canyon I drive up to get home. One was a person walking their dog on a leash and a mountain lion ran out of the forest, grabbed the dog and ran off.
That is how it is with all the dogs we have had. We have a Shitzu mix and a pure bred Cocker, and two that are.... well we are not sure. They know their job is to keep the intruder busy while I get the fire power.
