Pop Goes The News — Two months after picking up rescued puppy Beemo from a shelter in Montreal, U.S. Olympian Gus Kenworthy is mourning her death.

In an Instagram post, the freestyle skier said he and boyfriend Matt Wilkas “are beside ourselves trying to cope with her loss.”

Beemo was one of more than 80 dogs rescued from a South Korean dog meat farm by Humane Society International earlier this year. Beemo, a jindo/husky mix, was living in subzero conditions in Gyeonggi-do province.

In March, Kenworthy was in Montreal to collect the dog.

On Saturday, he said he was concerned about Beemo when she showed decreased appetite.

“There were several trips to the vet and on our final visit this past Thursday I asked them do a full body scan in case there was an underlying issue they had missed,” Kenworthy wrote. “Beemo went into a panic attack during the x-rays and her breathing became rapid and shallow. The scan revealed that her lungs were deteriorated and that her heart was too big for her body – a birth defect we had no way of knowing about.”

Beemo was transferred to an emergency clinic where she was put on a respirator.

“The ER doc told us that even if we’d somehow spotted the issue earlier it wouldn’t have made a difference in the end. He said that she’d been living on ‘borrowed time’ from the get go,” Kenworthy explained.

In his heartbreaking post, Kenworthy described Beemo as smart, playful and “the best thing that ever happened to me.”

He added: “I feel so fortunate for our borrowed time together. I’ve never loved anything or anyone in the way that I loved that dog and she is and will always be deeply missed.”
