"I hated Sinn. I genuinely felt a deep rage for what he had done to my son. Sinn was always a good dog, extremely obedient and protective and not at all aggressive. He's hyper-active and hyper-sensitive but wants to work and loves to be commanded. I love my dog, and nothing like this had ever happened to me before. But it's my son. I don't love anything more than my flesh and blood," Kroy told the mag.
