WATCH: Jason Kelce’s dog, Winnie, has passed away, leaving the Kelce family devastated; I lost part of my soul

On Thursday, Kylie, 31, shared a carousel post of their dog to announce the news.

“When I was in high school I had a folder on my desktop labeled ‘Gods gift to earth,’ ” she wrote. “It was images of Irish Wolfhouds that I had collected from Google. I had fallen in love with the breed when I was a young and never let my fascination with them fade.”

“It all lead me to Winnie and holy s— did she live up to the hype,” she added. “She was everything I had hoped for in a wolfie and more.”

“I lost part of my soul today, but I know she is at peace,” Kylie continued. “I love you, Winn. You will always be my first born child.” In the tribute photos, Winnie was shown happily lying down in the garden and on a blue and white blanket. Kylie also included a snap of her and Winnie looking at each other on her wedding day. The post then featured a snap of what appeared to be Jason, 36, stroking Winnie’s fur.
