absolutely wonderful! my little furbaby kept marking in the house and everything revolves around him. Kara taught not only my dog to trust me but to trust my dog more, which in return makes everyday hikes and car rides that much more enjoyable with my best friend by my side. Jax no longer marks in the house and listens so much better than he use to. I highly recommend k9 addict dog training to anyone with any dog: small, big, old or young!
