I am from IL..I was by Peoria (live in AZ now) I worked with a vet who was very into her Dobes. She competes in agility with her male, Hawk, and I believe she's started with her younger female. She also competes with her GSP. While she doesn't breed, her male came from a good breeder and I'm sure she'd be able to refer you to someone. She's very into proper health testing and doing sports, so I'm sure she'd make sure to refer you to someone with the same goals. The last I knew she'd switched to Dunlap Veterinary Clinic 2, so I'm sure you'd be able to contact her. Her name is Carol Kluka. If nothing else, if you go to any agility trial in IL or the surrounding states on any given weekend, she'll likely be there :p .
