If it needed to be said, allowing dogs excludes people. We allow dogs into our cities in exchange for dog owners being responsible. Unfortunately, many dog owners don't abide by those rules and let their dogs run around off leash. People who are scared of dogs should be able to go out the front door without worrying that they'll run into a dog.
I'm a dog lover but their are a huge number of irresponsible dog owners at Allan Gardens who think it's fine because their dog is 'cute and wouldn't hurt anyone'. People MUST come before dogs. I'm all in favour of a few dog free parks except many dog owners won't care and will bring their dogs any way. There will always be selfish inconsiderate rude people who do as they please.
