We're very happy that our friend referred us to Don's class. The training that happens is as much (if not more!) for the handler as well as for the dog. We saw a big improvement in our dog, who is "obnoxioulsly happy." So, so happy we took this class, and looking forward to more. Don, Pat, and Ed were wonderful with us, and really "got" our dog. Can't say enough good things about it--loved this class! Thanks for a great experience.
