Our old lab/shep cross died at home of naural causes and it was a beautiful thing. She had a chronic illness for at least the better part of a year and her back end was gone, but the day she died was not out of the ordinary. However, in the night she got herself up, god knows how, and made it to the back door and I let her out. When she came back in she didn't want to go to her bed in our room but instead made her way to her day bed. In the morning it became very clear that she was dying, and I had the luxury of being beside her until the end, some 8 hours or so later. It was a gift for both of us.
