I sent my dog to http://www.perfectionkennel.com/ just north of KC.
THE BEST PEOPLE in the world as far as I know. I sent my 5 month (at the time) Gordon Setter to them for a month last year. It was EXTREMELY rewarding to see my dog play with them while I visited them. I knew they were extremely gently with him because Shadow loved both of the trainers (it's a wife-and-husband operation). They have a extended training session when they take dogs up to SD for training.
They were extremely resonable (400/month) which if you were to simply board your dog somewhere, it would cost you 10-15 dollars a day anyways...
I'd give them a call. Tell them Shadow said HI!
