And some of us who have had to let a pet go wonder if we did the right thing. My Dyna has been gone a year now and I still struggle with my decision. She wasn't in any pain, But had not moved a muscle over night. She was happy to have me pet her for hours while I waited for the vet to open. Her heart was the size of a melon. There was nothing I could do to save her. But a year later I wonder what If? Having euthanasia available for humans would be even harder to justify.
