The gold medallist took to Instagram.com to post a video of herself in a hospital bed, moments before she went under the knife to repair her right hand.
"So the story is that my dogs got rowdy fighting over a dang Frisbee and I tried to break it up but got bit instead. Fun weekend," Vonn wrote.
Tiger Woods' ex-girlfriend had to have multiple stitches in her right thumb, and Vonn thanked U.S. ski team physician Dr. Randy Viola for helping her during the incident.
On Sunday (08Nov15), Vonn assured her fans she's already back to normal, by sharing a video of herself back on the ski slopes at high speed, writing the caption, "Dog bite is fine."
The injury is yet another ailment Vonn has had to deal with this year (15) - three months ago, she suffered a crash during training, which left her with a broken ankle. Vonn insists she'll be fit and ready for the World Cup giant slalom in Aspen, Colorado, at the end of November (15).
