McDougal taught pre-kindergarten before winning a swimwear competition that launched her career as a glamour, promotional, and swimsuit model. Since her appearances in Playboy, she has extended her career into a wide variety of appearances in mainstream media, including other magazine modeling, television commercials, and minor acting, with mixed success. She has been a successful fitness model, with multiple magazine appearances including being the first woman to appear on the cover of Men's Fitness magazine.

Since her Playmate days, she has maintained a largely private social life. The revelation of an alleged affair with Donald Trump from 2006–07 has put her into national headlines before and after the 2016 United States presidential election.
