Pit bulls are very friendly until they aren't.
Apparently Great Danes are like that too. They can snap in a second and just kill you after 8 years.
I've had Great Danes and never once had a problem, nor have I ever heard of them being aggressive. I know things change however, ever since neegroes and browns started getting certain dog breeds and over breeding them and making them aggressive.
The things these people have damaged and destroyed, well it's karma when they get what they ask for.
Last year a woman was mauled to death and partially eaten by her 3 Danes. I did more research after that. Poodles are on the list too.
