Fred, Maybe you will understand it if I say it this way:
Dogs can get "mental" from problems such as these and would require you to: 1. put it down OR 2. sedate it till its quality of life was severly reduced.
I'm not sure how to address the issue regarding how death might be an improvement in quality of life but sometimes it can be.
