Had this happen to me sort of. Delivered food to some people. They opened the door and their large barking collie (mix?) got up in my face pushing me back, and the 2 men (30s) just *stared* from their door frame as their dog was attacking me (without actually biting, just jumping at me while I was backing away trying not to fall, barking, and threatening to bite). Dog stopped when I finally made it out of their property. They then yelled that she’s all bark. Usually people hold back their dogs at the door, put them in a closed room for a moment, or would run out to restrain the dog and profusely apologize. Especially when it involves a stranger who just helped you out. It was a bizarre encounter that left me shaking at the time. And I love dogs!
