Here are some in IL. The first one is the Lake County Forest Preserve---there are about 4 different parks---my favorite is Wauconda...huge and fenced. We've had a Doodle Romp there. The second is DuPage County but I haven't been to that one.

I am totally hooked on Dog Parks. They just make me laugh. I love to see all the different dogs and hear their names.
