Ousted at the dog park

Everyone around here has a dog and the local dog park is quite the hang out. In fact, I was sure that it was going to allow me to meet all sorts of new people. Well we may just be ousted from the dog park. Iris is great when it comes to playing with other dogs but Crumley has never really been around other dogs before and turns into Mr. Aggressive as soon as he sees another dog. We think he's partially playing and partially trying to dominate the other dogs. We show up and all the dogs are happily playing. We let Iris off her leash and she starts happily playing. We let Crumley off his leash and he starts barking and trying to scare all the other dogs and children away. In fact, two families left within minutes (seconds) after we let Crumley off his leash. We had to round him up immediately and let Iris have all the fun by herself. So, no, I don't think we're making any new friends any time soon.
