It's well known that dog is man's best friend.
But Wiley the wolf-dog was pretty fond of it's owner's late grandmother Gladys - so much so that he appears to cry at her graveside.
In this heart-breaking video, posted to YouTube on April 14 by user SarahVarley13, the adorable wolf-dog lays on the tombstone, shaking, and makes what appear to be sobbing noises as the family gathers around him.
The handler can be heard in the 10 second clip saying 'We miss her too,' as she comforts the dog.
The video has garnered some 362,000 views since it was posted to YouTube.
It was also posted to the website of the Lockwood Animal Rescue Center, a Ventura County, California, shelter that specializes in the care of wolf-dogs and horses.
The LARC website describes Gladys as 'a family member, and a supporter' of the animal rescue center.
