One word for this training: AMAZING! The results were amazing, beyond noticeable! The techniques are easy and effective. I was concerned and stressed at first, but that went away as the training progressed. I've already recommended Jeri and Bark Busters to everyone who would listen! Jeri was great! Friends visiting the next day wanted to know where my dogs were as these couldn't be the same dogs! They said visiting was actually pleasant. A huge change in 24 hours! I can't say enough positive things about Jeri and the training.
