HOLLYWOOD, FLA -- An 11-year old girl has undergone successful surgery to reconstruct the lower part of her face after being attacked by a friend's dog during a sleepover.

Jacklyn Tucker was at a friend’s house for a sleepover Tuesday night.

She told her dad she fell asleep on the family’s couch.

At some point during the night she rolled off and landed on the floor.

When she opened her eyes, she saw the family’s dog, Tanker, standing in front of her, growling, according to the Palm Beach Post.

"I just laid there, and I closed my eyes, hoping the dog would just go away," Tucker said, the Post reports.

Instead of going away, the Jack Russell terrier-English bulldog mix pounced on the girl's face, tearing off three-quarters of her upper lip and part of her nose.

In order to repair the wound, plastic surgeons took tissue from Tucker's bottom lip.

"It's called a lip switch," said Dr. Drew Schnitt, at Joe DiMaggio Children's Hospital told ABC News.

According to Schnitt, surgeons take a wedge from the lower lip, flip it upside down and insert it into the upper lip.

"In two to three weeks, new blood vessels will grow into the tissue," he said.

Tucker will then have to have another procedure.

Tanker, the dog, was surrendered to Animal Care and Control, according to local reports.

He will likely be euthanized.
