Take your dog to the veterinarian to be sure he/she is current on vaccines, flea/tick and intestinal parasite preventatives before exposing to other dogs at the dog park.
Know how to control your dog if a problematic situation arises by teaching them basic commands.
Find an ideal spot to keep your dog safe while playing. Ask around for recommendations and do your research.
Pack some basic supplies such as a leash, toys, bags for waste disposal and drinking water until you know what the dog park provides.
Keep an eye on your dog at all times. Be prepared to quickly and safely remove your dog should a situation arise.
Use caution if a fight occurs. Never try to intervene physically as you may be injured. A horn, water or tossing an object are the best ways to break up the dogs.
