Lindsey Vonn: Butt Holes, My Dog Ate My Pants

Lindsey Vonn's dog chewed up her workout pants over the weekend ... but she didn't realize it until it was too late.

Lindsey posted the pic on social media and wrote, "I love Mondays...especially when you get to the gym and your trainer starts laughing at you because your dog ate your pants...literally."

Ruff morning.
