Our 7 year old dog was having a lot of aggression issues towards anyone that came near me. He also couldn’t handle loud noises (door slamming, barking, etc.). Brittany gave us the tools and training to improve his reaction to loud noises and decrease his reaction to people coming near me. While it’s still a work in progress (as with any training), I can definitely recommend Brittany and K9 Harmony as a great trainer.
