I have looked and looked, but can not find a defense for killing a dog in self defense. Section 9.22 is the only section that MAY allow it. As far as I know, there is none.
It is not covered under 9.32 of the Penal Code (a dog is not "another"), nor under 42.092 (a domesticated dog is not a dangerous wild animal).
Anyone that knows where there is a defense that allows you to kill a dog in self defense I would like to know. This is for my knowledge. I do not want opinions (I have plenty of those myself), please provide the section, I do not need a link.
Thanks to anyone that answers.
