We have a lot of aggressive staffies around here owned by teenage gobshites that think it is clever to teach their dogs to attack other dogs. Had one go after Willow and Tam, put the dogs behind me and threatened to call the police . Mouthy little git decided against it after telling me his dog could kill mine. I now avoid all staffies, can’t take a chance on it any more.
The other thing that winds me up is people letting bitches in season off lead to go up to any dog they fancy, then they tell you she is in season. They did this to my sister with Farrokh once, she just said that fine he is entire and there was a hasty scrap to put the bitch on a lead ;D
