Police in Las Vegas were called to the home of a 23-year-old woman earlier this week after her neighbors complained that she was having sex with a pit bull in broad daylight in her own backyard.

When cops arrived at the scene they found Kara Vandereyk "naked and on the ground," engaging in an unspecified sexual act with the dog.

According to the police report, Vandereyk, who appeared to be on drugs, greeted the officers with a "hi" and proceeded to "touch the dog in a sexual way."

She was covered with a blanket and asked a series of questions about her identity, the current date, and the name of the President, none of which she was able to answer.

Vandereyk reportedly told the officers that she was "bipolar," and claimed to be on "prescription medication."

Animal control was called in to remove the dog, and Vandereyk was arrested on a charge of open or gross lewdness.

Vandereyk was looking much better just six months ago, when she was arrested in Utah for an unspecified crime.
