I adopted a wonderful rescued bulldog puppy this summer, but began having difficulty with his anxiety-based aggression. I thought it would just be something to manage and work around and assumed that - because of his abusive background - that it was "unsolvable." Then his aggression escalated and he began snapping at and even biting us when we'd take him out for walks. I emailed Bark Busters in a panic after he drew blood one day and after ONE lesson with Marsha, he is SO much more relaxed and happy! He no longer feels the burden of having to "lead" our pack. No more barking when we leave the room, no more growling/lunging at us on our walks. He doesn't even try to guard the front door when he sees me getting ready to leave - he watches calmly, lounging from his spot on the bed :) Without all that stress he is calm and happy, walks behind me down the stairs (no more pulling/barking the whole way) and I am thrilled to see him this relaxed!! I loved that this method doesn't use any form of physical force, no yelling and it isn't even food based. I didn't believe in miracle cures, but Marsha - and the Bark Busters technique - is INCREDIBLE. The lifetime guarantee is pricy, but worth every penny. If you think your dog's issue is "incurable" ... this training method is the thing to try. Thank you from me and my pup!
