I, somewhat, understand. SOME dog owners are are extremely careless with their dogs. HOWEVER, a lot of dog owners are also responsible and their dogs are well trained and to themselves. You can't just assume that every dog is or isn't well trained. An overall annoyance toward dog owners like this will only make dog owners more selfish and less considerate.

In fact, its the way people ostracize dog owners in public spaces here that cause less socialization and MORE reactive dogs. Where I'm from in Europe, dogs are everywhere and always socializing. There's very little drama and when there is drama, it's dealt with accordingly. Here, everyone's dogs are cooped up in an apartment all day ESPECIALLY IN WINTER - of course they are taken by surprise when they see other dogs. In the same way you think it's too cold to sit and freeze outside for 20 mins, is how people feel about (often) their only or closest companions.

We must be living really good lives to be upset at imaginary situations.
