People Socialization
Excellent source of people-people social interaction.
Dog-oriented people can meet and interact.

Dog parks allow dogs to get adequate physical and mental exercise, thereby lessening destructive and annoying behaviors in general which can benefit society as a whole.
Educational
Good opportunity for owners to learn about dogs through observation and provides the opportunity to learn from more experienced owners.
Opportunity for well-mannered-dog advocates to demonstrate how they turned their dog into a well-mannered dog.
