It's cold out there, and Dr. Ernie Ward is back, this time with an eye-opening experiment showing how dangerous it can be to leave your dog outside when temperatures plummet.

The North Carolina veterinarian first made his way into our news feeds with a viral video demonstrating the harmful effects of leaving your canine companion in a hot car. Now that the weather has shifted to the opposite extreme, Ward is just as committed to making sure pet owners understand how to keep their pets safe.

To demonstrate that it's never OK to leave dogs outside in freezing temperatures, Ward spent as long as he could outside in a doghouse while temperatures sat well below 32 degrees. Even though he was bundled in warm winter gear, Ward was almost immediately uncomfortable. In just 30 minutes the temperature inside the doghouse had dipped to 20 degrees. Despite his best efforts, he only lasted four hours, and was forced to call it quits by the time the thermometer hit a painful 15 degrees.

"No dog is biologically adapted to handle this," he said.

According to the American Veterinary Medical Association longer-haired and thick-coated dog breeds, such as huskies and other dogs bred for colder climates, are more tolerant of cold weather, "but no pet should be left outside for long periods of time in below-freezing weather."

Watch the alarming experiment above, and do your pup a favor and take him inside when temps fall.
