This remarkable German Shepard was the loving pet of Argentinian, Miguel Guzman. The dog, named Captain, ran away from his home when Miguel died in 2006 and family members eventually found him at the gravesite where Miguel was buried.
Interestingly, Captain seems to have intuited where his master was laid to rest as the family never took him to the gravesite. Although they initially tried to get him to come home, Captain refuses to leave the cemetery and has been keeping vigil there for 6 years now. The cemetery staff has taken over feeding and caring for him while he looks over his master.
