Dusty is by far my hardest dog ever. He is australian shephard and husky. He is super duper hyper. One word always comes to mind when I look at him...estatic. He knocks you down cause he's so excited to see you, he does back flips and knocks stuff down, he sees a person or kitty and he runs off to see them, he's got this shrill high pitched bark that can break glass... These all sound like things you can break, right? Nope. Dusty is so happy that reprimands do not phase him. I have tried both physical and verbal punishment. Nothing matters, he is still happy as heck. I have never seen Dusty get his feelings hurt or seen him miss a beat when I discipline him. I've just tried to be consistant and hopefully sooner or later, he'll grow out of it. He's getting a little better.
