There's a Dog Park in Edmond as well, but it doesn't have a pond for the dogs to get into (which can be a plus if you're not in a mood to give your dog a bath afterwards).

I agree that it is usually the owners that are the problem, especially when they don't correct over-aggressive behavior. If you are unsure, go on a day when the dog park maintainers are there. They will ask owners to leave if their dogs don't behave properly. Also, take your dog on lead into the park. When you feel comfortable, let them run free!
