Convicted dangerous dog owner Brian Hill now regrets pleading guilty in the Carolina Anderson mauling case, saying that he is still convinced that his dog was not responsible. He is also angry that his partner Thomas Owen was jailed, as he was not the dog's owner, and is very concerned for his welfare after a vicious attack in prison last Saturday which put Owen in hospital. Owen and Hill have not spoken, due to rules which prevent recent inmates from visiting and restrictions on inmate phone calls. Hill says he gained a lot of knowledge in prison, as well as making some friends. "I dyed my hair black [before entering prison]”, he says. “It gave me a few days of anonymity. By the time they found out who I was, they were my friends."
