WOW we had a situation where we took in an aggressive fear biter. We did not know that he was this bad. BUT luckily for us Bark Busters helped us immensely. We were walking on eggshells due to his aggression and not knowing what would trigger his biting. After one session with Lisette we have the situation well under control. It is slow going and he did not develop this behavior overnight but in a week with doing the exercises and staying consistent we have seen a huge change in Zorro. He is listening better and he has only growled at me once. Thanks to Lisette and Bark Busters we feel that Zorro is on his way to being a well adjusted dog who will be able to be adopted out.
