I think it is very uncommon to not allow intact dogs into a dog park. That would essentially mean any dog that is a show dog, used for breeding, or owners who simply make the choice to not alter wouldn't be allowed in.
What is so weird is that type of dog is the kind he loves to play with. He can be pushy himself and loves to play ruff. He seems to have this issue with dogs he has never met. Most of the time his behavior with the other dog starts out as play then changes to him snapping at them. He is not trying to kill them its almost like he is trying to put them in their place? If that makes sense.I think it is very uncommon to not allow intact dogs into a dog park.

I think WAY more common is that females in heat are prohibited, that sign is pretty much on every dog park. Anyone who brings a female in heat to the dog park is a nutcase.
To the OP: Is your dog neutered? If he is, it could just be he doesn't enjoy rude, pushy, dogs. I try to take my guys over to an area of the park away from everyone else if there is a pushy/not nice dog. If they follow us, I go over to the smaller separate area (usually reserved for small dogs, but there are never any around). Dog parks are so hit and miss, it is difficult to say what kind of experience you'll have when you go.
