I don’t have the energy to argue. My dogs just sleep so sound when they’re in my bed and they’ve also never been put in a situation to protect me when they’re inside. They’ve protected my property and myself a many of times while outside though! My female is all bark, but my male is all bite. I’ve always wanted to get him trained bc I know he has the drive in him, and I have really good control over him, but when Im not around he will tear someone up only when they come onto “his” property of course. I’m always with them so I can monitor the situation and his “out” and “recall” is amazing, so that always comes in handy! I’ve always wonder how they would react if a stranger came into my house in the middle of the night, though!So you really aren't interested in opinions, you just want to argue. I'm good with that but the mods close threads unless we're polite.
Your dogs could seem more alert outside because they are insecure in their surroundings. My protection dogs didn't usually waste much energy barking, and the dog that I least expected to protect me jumped over me to bite the stranger that walked into my room. She didn't waste much energy barking either.
As I said I live where it's cold. Dogs outside here spend lots of time alone come winter. Not my thing.
