“The German Shepherd was a total coward”
The GS probably had the best response of all of them. Actually, ideal would be a combo of some of these dogs.
The Rott did warning barks ahead of time, but checked out when the guy was in. The GS apparently (no film prior) let the man in w/o barking but seemed suspicious as time wore on and barked more at him.
Frankly, you don’t want a dog who just indiscriminantly charges and rips everything. There are many times “strangers” come to your home that you don’t want ripped apart. Especially if you want them to care for the dog. My dear-departed Perfect Dog GS (”only” 60 lbs as a GS should be, not oversized) always scared the !%##!%$# out of people outside the house, and she knew the INSTANT someone touched the grass on our lawn 300ft away down a steep hill just by hearing. Excellent “watch” dog. People coming to the house itself were scared. She ran after 1 boy when she slipped through the door after he stood there asking us to mow, but she stopped going for his ankle the INSTANT he obeyed my order to “STOP RUNNING!” and ran right by him. She always barked at everyone but those always in the house, regardless, but if you used her name, she’d let you in while barking (ask cleaning lady, my friend who took care of her on vacation). Cautious, anyway, but she’d watch you until she felt comfortable.
I want a dog that walks the line. Not enough are smart enough for that, though.
Not a fair test for the German Shepherd.
Let the intruder enter the property and threaten the occupants, then see what happens.
My German Shepherds are unlikely to even bark at intruders, unless they brought their own dogs. But 200 pounds of them will intimidate most would-be intruders.
