A heartbroken dog cannot handle the loss of his owner. He sobs on his tomb, unable to cope with his loss. This is a true example of how deep emotions dogs spread towards their owners.

Wiley the wolf-dog had been so devoted to its late owner, Gladys, that it was difficult for him to comprehend that she had died.

A distressing video shows the bereaved dog wailing uncontrollably at Gladys’ burial while lying sadly on her gravestone.

The video, which has touched the hearts of thousands of viewers, shows Wiley sobbing and shaking as family members gather around him.

In one scene, a family member is seen reaching out to soothe a crying Wiley and saying, “We miss her too.”

Since it was shared on YouTube by user SarahandtheWolves, the video has had over 9,174,611 views.

Wiley is one of the military wolf-dogs that treat veterans suffering from Post Traumatic Stress Disorder after they return from combat, according to the YouTube account SarahandtheWolves.

The military wolf-dogs give rehabilitation and care to veterans through LARC, the Lockwood Animal Rescue Centre, which specializes in wolf-dog and horse care.

The user also supplied an explanation to allay any fears about Wiley’s health.

“I’m not a vet, so I can’t say if he’s reverse sneezing like some of you,” SarahandtheWolves wrote.

“I can assure you that he has never done it before and has not done so since. I may be anthropomorphizing his acts, but this is how I choose to cope with loss…”

“Also, for those who say he’s dying, I assure you he’s not. The sanctuary has a veterinarian on site, and Wiley is great.”
