There's an awesome Doberman Rescue in IL, I'd assume it's not too far from Chicago. We were looking for a Dobie from them, but ended up getting a pup. Dobermans are VERY active dogs and would fit in perfectly with anyone who is very active. Although, I will say they are VERY energetic dogs. If you get the dog from a rescue you will know it's temperament and if it's able to play safely with other dogs. The dobie rescue in IL fosters them in homes with children/pets so they are really good at knowing what the dog is really like. Some insurance companies won't insure you if you have a dobie, so you might have to look into the breed before you consider it.

You've had shepards before so you know what they are like. Irish Setters are awesome. I had a Dalmatian when I was younger. She was VERY active and a very nice dog. She stayed active till we had to put her down at 15 years old for multiple health reasons. Boxers are awesome and Very active. Retrievers are all around awesome dogs. I'm not sure if you're looking for a particular look/attitude.
