Mochi “Mo” Rickert, holder of the record for the longest tongue on a living dog, has died, according to Guinness World Records.

The female Saint Bernard’s tongue measured 18.58 cm (7.3 in), Guinness says. Mochi held the record for five years.

Mochi was featured on the cover of "Amazing Animals," a book by Guinness World Records.

Mochi was a rescue dog in Colorado. She made more than a hundred appearances at schools, nursing homes, events for animal rescues and TV. Mochi was featured on the cover of “Amazing Animals,” a Guinness World Records book published in 2017.

Owner Carla Ernst said in a 2017 video by Guinness that she used Mochi’s favorite snack, peanut butter, to show people how far the pooch’s tongue could reach.

When Mochi was confirmed a record holder, Ernst said, it made “all the water and slobber we’ve cleaned up over the last six-and-a-half years well worth it.”

Guinness announced Mochi’s death October 20.

“Mochi had an impact on nearly everyone she met. She rescued so many hearts in her life… what a joy this journey has been,” Ernst told Guinness. “She was the most amazing animal ever. We miss our precious furry child!”
