"Here in the city, people generally tend to get their dogs trained properly" is a blanket statement with several qualifiers. In Chicago alone there are dozens of dog "rescues", and many of the dogs are sourced from negligent owners living in the city. Anecdotally, I had neighbors who were young, educated, wealthy white males who owned a dog for whom they could not provide adequate care - due to their schedules and priorities, the dog became the landlord's primary responsibility. There were times I fed and watered the dog out of concern for the dog's well-being, and I'm the furthest thing from a fan of most dogs (for similar reasons to OP). That said, it would have been presumptuous and rude to 'report' their negligence and get the dog taken away either by a rescue or animal control, and so I didn't. I doubt this was a unique scenario.
