One of Malia Obama's friends was left bloodied and scarred after being bitten by the first family's dog Sunny on a visit to the White House on Monday.

Social media posts which surfaced online show the teen - who DailyMail.com is not naming - getting stitched up at the office of the president's physician.

'I f****** hate Sunny' the girl wrote in one picture, showing her laying down on a doctor's chair while Malia smiles nearby.

'Malia thinks it's funny,' the girl writes in another Snapchat photo.

Sources tell TMZ that the girl, who is 18, was bitten by Sunny when she leaned down to to pet and kiss the pup.

Dr. Ronny Jackson, the president's physician, reportedly evaluated her and decided to stitch the wound up.

The teen was allegedly upset when he told her it could leave a small scar.

While Malia graduated from high school last spring, she is still living with her parents because she's taking a gap year before starting at Harvard next fall.

Sunny is the younger of the Obamas' two Portuguese water dogs, a generally docile breed. The elder, Bo, was promised to the Obama daughters if their father won the 2008 election. The first family bought Sunny from a breeder in the Great Lakes area in August 2013.

This isn't the first time that Sunny has misbehaved in front of guests. She jumped on a two-year-old girl at a White House Christmas party in 2013

While Bo has been an upstanding First Dog, his four-year-old female companion has been more unruly.

Three years ago, the dog knocked over a two-year-old girl at the White House, who was attending a Christmas party for military families.

Sunny has also been a bit harder to potty train than Bo.

In an interview with People magazine, the president and first lady revealed that Sunny has a penchant for defecating near the Lincoln Bedroom.

'So Sunny is a wonderful dog. But there have been times where she just decided that the area near the Lincoln Bedroom and my office – at the other end of the hall from her crate – is included in being outside when it comes to pooping, which is not true. It’s still the inside. She didn’t always understand that,' the president said.

'She knows that she’s doing something wrong because she’ll run and sneak [past me],' he said. 'Sometimes I’ll be in my office, and I’m doing my work and I’ll see this like scurrying - and I got to get up and run before she does her thing, because if I’m too late then there’s a little gift that she leaves.'

The first lady said that Sunny hasn't done this in awhile, saying 'she's gotten much better'.
