I really do feel terrible you lost your dog, but you have now gone from one dog to all dogs. From asking to demanding. And now into putting down someone who took you at your word.
My cousin had a dog named Domino. Domino, as fun-loving as he was, was truly one of the stupidest creatures I've ever met. He was quilled by porcupines twice, skunked twice, and bit by copperheads four times. (Surviving all that, but not surviving forever.) Protect? He couldn't even protect himself. Truly, truly dumb.
You are certainly free to believe whatever you want out of the mind that you have, but don't assume that means we all have to believe the same, nor are we all making it up as we go along too. dcontroversal gave you verses from God's word. You asked. He answered honestly, with dignity, and truthfully. If you don't want an answer from God's word, then ask wherever people are happy to give you what you want, instead of the truth.
"Bible Discussion." I like this board for its focus, not for a place were people can get others to agree without any backup, support, or reality getting in the way.
