[A vicious, attacking dog can be stopped without killing it. The question is how much pain and bites are you willing to endure to stop the dog and restrain it so it is unable to continue attacking. ]
None. As for me a vicious dog should be killed.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
