@planet molosser, I think rhodesian ridgebacks have too much of a prey drive for me. They sound a bit too hardheaded and independent for my taste based on what I've read about them but otherwise they would be an option. I do know many of the things I ask are individual and also up to the training provided. Some breeds are a more natural watchdog than others though. I don't think it's even possible to train for example my cavalier into a watchdog.
Pugs look like they've ran into a door... not quite for me. Pomeranians are too barky, they bark at everything. There'd be no way of telling if he's barking at a stranger or a leaf falling down from a tree. If I want a tiny breed as a watchdog I'd go with a papillon but I really want something bigger.
Poodles.. no thank you. I don't want any breed that would require professional grooming. And I think poodles look a bit silly (no offense to poodle owners).
I do like the Dane suggestion, as well as the Newfie. Both breeds will be high on my list to check out further.
@mrose, it is a good idea but the main problem about those particular three breeds is not really me. I know better now than to judge a whole breed based on a few bad behaved individuals. There would have to be something in their body language telling me to be cautious for me to be afraid of them anymore and that stems down from my old fear of dogs. I used to be absolutely terrified, I couldn't go anywhere near a dog of any kind. Now I can't live without them. :lol-sign: Anyway I have never seen a friendly dobe or rott, but I know they exist. I have met some amazing GSDs and if I were to pick a breed out of these three, it would be a GSD. But I highly doubt my relatives would change their opinion so that would leave me with almost no relatives coming to visit me and they would also not take care of a GSD for me in case I have to go away somewhere like they do for my cavalier. It's just easier to try and find a breed both I and they can live with.
Xerxes, I won't rule out getting an adult but I have a feeling an adult fitting these criteria in my country would be almost impossible to find.
