What explains the bonds between a dog and its owner, what accounts for things that are difficult to put into words?
When Paco’s owner, Kelly Black, was killed in a traffic accident, her uninjured pet knew only how to show his grief by lying at the spot where she died.
CBS said Ms Black, from Jacksonville, Florida, and her pet were inseparable.
Ms Black was killed last week in an an early morning traffic accident that is still being investigated by police.
Local media captured the images of Paco, lying on the road for several hours. He stayed there until members of Ms Black’s family came and collected him.
