I ask this question after talking with a friend who did just that. He has known the time was coming; that his dog would only suffer through another winter if he didn't put her down. So, last week he dug a deep grave on the hillside behind his house, packed the dog onto the four wheeler (because she couldn't make the walk), took her up to the site and shot her through the chest. He buried her and when the kids came home from school he told them she had died that day. Taking the two youngsters up to the grave, they said their goodbyes and placed a cross as a marker. The boys cried. My friend did too.
