They were actually used by a friend of mine. I believe they somewhat gave up on her energetic dalmation! We just had ours trained at PetSmart and they did great. Then again, ours are labs :)
We have a very naughty German shepherd and we interviewed them but the trainer they sent out to sell the program to us was scared $hitless of our dog. It was actually rather humorous to watch. We went with a private trainer and she was great. :) The Boston's just went to the local college puppy kindergarden and did great.
