Brett Bennett from Seattle had posted YouTube videos of his Rottweilers Brutus and Hank, but the most recent addition to his videos was a very sad one.

Bennett posted a video of one of his Rottweilers Brutus resting his head on his brother Hank, who passed away during the night, according to the U.K.’s The Mirror.

“Brutus never whined or cried out in pain in the two years I have had him,” wrote Bennett.

He added, “But clearly you can see in his eyes, he is crying for his brother who had passed as his world around him just crumbled. We both grieve and cry for our brother. This is proof that animals DO have emotions and feel pain just like we do.”

Although the video, which has gone viral, is only 1 minute 56 seconds, the incredible sadness Brutus feels after his loss is captured, enough to make YouTube users feel his emotions.

“Seeing the pain in his eyes literally broke my heart,” wrote YouTube user Angela H.

Another social media user Sophie Rutigliano commented, “Hank was such a beautiful dog. I’m so sorry for your loss.”

The viral video has garnered over more than 4 million views and 13, 595 likes and counting.

“Let the world know animals feel love and pain just like us,” wrote Bennett.

He added, “Don’t let Hanks passing die in vein with him. Please share our story.”
