I'm in LaGrange Park and have a 10 week old flashy fawn boy.
So far he loves my friend's male yellow lab, a chocolate lab from the neighborhood, growls at the poodle across the street, hates the King Charles Spaniel on the next block and LOVED the first boxer (80 pounds!!) that he met.
I'm game, there's a dog park I know of in Hinsdale.
Keep me posted!
