We've been very happy with the Bark Busters training our pup (and we) have received from Peter. The Bark Busters method of auditory cues/corrections work well with our golden retriever. I'm impressed that as she's getting older, I don't need to use the cues nearly as much or as loudly. Goldens are notorious "thieves" (socks, used tissue, you name it) but a low, soft correction from me now tends to get her to drop it-or stop whatever other mischief she's getting into. Peter is a knowledgeable, pleasant and very enthusiastic trainer, and we look forward to additional refresher training-for us as much as for our dog-as she gets older.
