I’ve seen dogs do enough in my time to realize you shouldn’t trust ANY of them unless you know them well and know their training. And I LOVE dogs.
This, with the addendum that if I know the owner and his/her training methods and general habits with dogs, I'll be more likely to be relaxed at the outset.
I love GSDs.
I have a history with GSDs in a working capacity.
I currently have a yellow lab, and won't have another GSD until I retire. If I can't provide the time for proper training, exercise, and socialization....I don't have any business keeping the breed as a companion.
Needless to say, I'm looking forward to retirement.
