That’s just wasting their time though, it’s clearly not an xl bully. Ok not much time as they’d know immediatly looking at the pics.
it does appear the op was freighted of both the dog and the man, and neither did anything wrong, both behaved well and were within their rights to be out, meeting with friends, family, kids etc.
no one should be encouraged to report people and dogs who are just going about their business and perfectly legit. That’s a shit way to behave and if everyone did it, the authories would struggle to cope.
The op needs to educate herself. And deal with any anxiety issues she has around men she feels looks intimidating ie counselling etc if something happened in her past.
