The bond between man and dog was put on display for all to see in this heart-wrenching photo.

Mike Petrosino, 21, has been diagnosed with cancer and had the opportunity to share one last goodbye with his dog, Rusty, at Massachusetts General Hospital.

The picture of the moment has since become a viral hit after being posted on Reddit.

Petrosino’s friend who put the photo on the site wrote:

My friend Mike was diagnosed with cancer in the 8th grade. He was given a three percent chance to survive the first year. Two days ago we found out that after eight years, the amputation of his leg, and four rounds of cancer that there’s now nothing that they can do.”

Petrosino’s brother, John, said the moment certainly got to the pooch, noting, “Rusty was very emotional when Mike said his finale goodbye,” he said. “Every time I come home these past two days, he sits near Mike’s favorite couch and whines, which is rare from him."
