If you feel that your dog does not have the appropriate behaviors to be in a dog park then contact your local DogSmith who can help you. DogSmiths run fun and effective "Grumpy Dog Classes"
Grumpy Dog and Dog-on-Dog Etiquette
These classes are for dogs that are reactive to other dogs or struggle with their focus in distracting environments. Dogs with severe aggression are not appropriate for this class. Dogs must have a solid foundation in basic obedience. www.DogSmith.com
