In this touching video clip, a dog appears to be crying at its dead owner's grave. Of course, dogs have the ability to grieve and miss their previous owners. It's absolutely remarkable that a dog can sense that someone has passed. This short clip below is sad, but it just shows us that dogs really are man's best friend. We wish this adorable dog the best, and we're very happy to see that he is with people who love him and care for him.
