Excellent topic again, German. I did not get a rottweiler for protection, either, but it is nice and appreciated just the same. We have a very sweet girl who I have to say has just about the lowest drive (except for our cats, but she is getting better) I have seen. We got her in October, and at the time, she was recouping from a fractured leg after being struck by a car. The day I brought her home, I did not hear a word out of her, she was calm and quiet for pretty much the first week. Slowly, we are bonding very nicely, and she has become very alert to the surroundings of our house, barking to let us know when someone is outside..she goes everywhere with me in the car, which is nice especially at night...and alot of times it is just me and her and I appreciate knowing that she would probably try to do her best to protect if she needed to.
I did not think she would have adjusted this well so soon, coming from a different environment, and recovering from her surgery, but she is coming along quite nicely, and we do walk at night sometimes, and I feel totally safe.
I do not know her background, but she is true to the rottweiler characteristics, and has the wait and see attitude. She doesn't bark at everything she sees, she seems very confident in just being a dog, and able to judge situations from right and wrong. She is actually a little more laid back, such as when we go to people's house, she will meet everyone and then go about her business, alot of times ending up napping on their floor..
I guess my point is there are some real laid back low drive dogs such as ours, who do also make good watchdogs also, maybe not as intense as ones who have been bred so, or with higher drives, but good enough for people like us. :)
