Yes, it's really hard to predict how they'll get along. My male was fine at the dog park, playing with other males, some of which were intact. I took him there both before and after he was neutered.
Then, one day we met up with an intact mastiff. I could tell right away from this dog's body language that he was Trouble. His owner was aware, too, and we kept the two dogs as far apart as we could.
Unfortunately, we let our guard slip as we were leaving the park. We were able to get the dogs separated before they hurt each other, but the mastiff's owner suffered a nasty bite to her calf.
Just be careful, watch the body language, and be prepared to intervene if things start to go south. As a safety precaution, you might want to leave the leashes on the dogs when they are playing, or have them on long lines/lunge lines so you have something to grab to separate them. NEVER grab a fighting dog by the collar. That will almost guarantee a bite.
