being a verteran and being in the military, i think he's probably relieved of duty at this point while the decipher how they are going to play this media issue.
as for him killing a dog, i dont think the military will care much. it is conduct unbecoming as far as i know in the uniform code of military justice, but when you teach people to kill, then well, there are always chances they may kill something they shouldn't.
i think its terrible what he did btw.
no need to kill the dog.
