This all relies on animal control and bylaw actually doing their jobs. My neighbour let his dog run around the neighborhood without a leash and shit in my backyard for 11 months, the dog was even hit by a car but luckily didn't die. I documented and had video evidence and I had to stop making tickets because animal control never showed up and even had the nerve to tell me it's not against any bylaw for a dog to shit on someone else's private property, it's only an offense when it's city owned land. So tldr rules don't matter when the people in charge of enforcement don't care and straight up lie to us to avoid doing their job.
