Use of Armstrong's Cabinet to put down Chocolate lab?

All I can picture is the pain she felt as the blades sliced through her body. They did not hit an organ to kill her instantly so there was pain involved. When they are "put to sleep" they ae out cold as the drugs take effect. There is only the pain of the injection. If you think this is death with dignity, I am glad I am not your mother or father. What would you do to me? But then what can you get for $15.00 now a days! And you were out in less time the it takes to go through McDonalds!
