Two of our neighbors have dogs (beagle, schnauzer) that have gone there. The schnauzer goes back once a year for "refresher" training. I don't know what training methods they use there, but I was told by the schnauzer's "mom" that they were not allowed to visit during the (I think) 2?-week long session. That sounds bad the way I wrote it - don't mean to cast aspersions - I just truly don't know if they use only positive reinforcement, or a mixture of rewards with pinch or choke collars etc.
We have gotten great results with our girls using just positive reinforcement, based on the book "The Dog Whisperer". We have a poodle would pull so hard on the leash that I was worried she'd injure her windpipe (which can happen in smaller dogs; we've since switched to a harness). Anyway, using this author's ten-thousand $ treat principle, she now walks very well on the leash - if anything lingers behind a little sniffing interesting stuff, but not pulling anymore. It took a commitment on our part though - long walks 3-4 times per week, with a treat bag with us every time. We still bring a treat bag with us when we walk, for the occasional positive reinforcement, but in the beginning we were rewarding almost the whole walk, every time she was in the "right" spot, so we could teach her not to pull ahead.
Oh - one more thing, the schnauzer mom was able to negotiate a better price than what she was originally wuoted, because I know they were priced quite high. I agree with the other posters though - you need to be trained too so you clearly communicate what you want to your pet.
Good luck with your choice - both of the dogs we know that went there are much loved and seem to be well behaved.
Someone obviously trained him before. I really can't understand how he ever ended up at the pound for 5 months before we took him. 
Now, with Skippy we'll see how it goes. He's just 10 weeks old. Not sure when I'll start him. I'd be thrilled if he'd just get the housebreaking routine!
This was supposed to be under the other dog thread.
