Dallas, Texas - Boregaurd the dog was returned to the Dallas Animal Services shelter by his owner at the end of March after eleven years. The reason? Only because his owner was sad to see him grow older.

The infuriating explanation brought the dog's Instagram video viral acclaim.

Animal shelter helper Vivian Powers shared the clip at the end of March, showing the trembling Boregaurd, who clearly doesn't understand what has happened to him.

"His owner surrendered him yesterday because he was sad his dog was getting older," she wrote in the tragic onscreen text.

"He was terrified and didn't want to move," she added.

In one scene, the furry friend is led outside on a "daycation" walk by volunteers.

"He kept [wanting] to go through that door," read the onscreen text as the dog's eyes can be seen darting around, looking for something – or someone.

Tragically, the pup thinks he will be able to find his owner on the other side of the shelter's front door.

"He was searching for his owner," Powers wrote.

"How do you even explain to him that they're not coming back for him..."

As expected, this situation goes down very badly with the Insta audience.

One commenter calls for the owner to be banned from ever getting another dog.

Someone else demands that people who do this should be treated in exactly the same way in their own old age.

There are also plenty of broken hearts and crying emojis in the comments section as well.

However, in an interview with Newsweek, Powers defended herself against the accusation that she had wanted to put Boregaurd's former owner on blast.

She asserts that she was only interested in drawing attention to the four-legged friend and his adoption case.

Reportedly, the dog is now staying with a foster family while he waits for a new forever home.
