ABC News' Micah Grimes reports:

One of the puppies that Olympic silver medalist skier Gus Kenworthy adopted while in Sochi for the Winter Olympics has died, his representative confirmed today. "Sochi," a female stray, died while Kenworthy's friend, Robin Macdonald, was trying to get the adopted puppies back to the United States for proper treatment, Kenworthy spokesman Michael Spencer said.

No words can explain what has happened here, good bye little guy, we will miss you. ???? Heading home on Tuesday.

In winning a silver medal and sharing the four puppies he saved from the streets of Sochi with the world on social media, Kenworthy became a household name during the Olympics.
