Probably a Rottweiler, I was drunk coming back from a party in a forest when a Rottweiler was looking to attack us (protecting his owner), the owner was with two prostitutes (most likely and didn't give a fuck what the dog was doing for quite some time). We were frozen in place to not upset the dog. I'd say a minute later he tells the dog to calm down... weirdest part there was a Rottweiler puppy present too who was licking my leg the whole time (i'm ticklish). Fortunately no one was hurt, but it was pretty scary. More so with my friends who were closer to the Big Rottweiler.
