Carol's bedroom was in disarray. The floor was covered with papers and magazines, the bed was littered from top to bottom, and food—both human and dog—was strewn about.

Carol's kitchen, which had taken our crew more than eight hours to clean, looked okay on the surface. But when Dr. Tolin started investigating, he found signs of unsanitary conditions: dead bugs floating on dishes stacked in the sink and the refrigerator full of moldy food. In fact, a pizza box on the counter left by The Oprah Winfrey Show camera crew the last time they were here—months ago—had attracted bugs.

And who could forget Carol's bathroom in which the shower was full of dog feces? Dr. Tolin found that the dogs had reclaimed the bathroom for their own use.
