I'm glad your dog park experience was so positive. We have a really neat dog park near us (neat for clark county which means 'fenced empty dirt field with garbage cans) and we used to take Badger to it, but too many times dogs got nasty toward Badger, nipping him. A few times, dognados came through, (tornados made out of wildy out of control dogs at the park...coined by ME) slamming into oblivious Badger, and he doesn't appreciate that either. We realized that sadly, we were taking him because it was fun for us, not him. Many people take there dogs to dog parks forever with no problems.
What is really nice about this area anyway, is that if your dog knows off-leash commands, you can take them offleash to any park. Your dog has to 'reliably come to you when called under all circumstances'. As long as nobody pulls out a cheesecake coated bouncy tennis ball, we should be fine...
