You missed the entire closing sentence. Your dog is good to YOU. A public event is not a place for pets. It doesn't matter how well you know your dog because your dog doesn't know a stranger.

Adding to that, if your dog bites someone are you okay with taking to the vet and paying $500 to kill it? Are you okay with taking the blame entirely and potentially getting your shit absolutely wrecked because of it?

This is such a stupid conversation. A dog is a possession. You own it. This like asking if you can bring a knife or gun to a fireworks show, it just doesn't make sense. Both those two things are infinitely safer than a dog because you can predict what they'll do.

What is wrong with people?
