Dog Mourns At Owner’s Grave

Stories like the one below make my heart ache. Wolf-dog, Wiley is a 'service wolf' with the program 'Wolves for Warriors' which helps veterans returning from war who are suffering from PTSD.

WIley was exceptionally close to his owner, Gladys, and appears to 'sob' at her headstone. Skeptics suggest less emotional reasons for his behavior, but the original uploader of the video said the dog had never acted in a similar fashion before.
