The price is determined by the dogs' intelligence, beauty, training and bloodlines, which for top dogs often trace back as much as 100 years.

"There's a show in Europe, you can equate it to sort of the Miss Universe Pageant," said November Holley, who runs the training program at Harrison K-9. "Julia placed in the top 50 dogs in the world."

The dogs are trilingual, understanding a combination of English, German and hand signals.

Some clients buy several dogs to use as both companions and guard dogs. And just days after the "Secret Lives" shoot, Lilli, Yola and Juna were all sold for their asking prices.
