She also makes house calls, sometimes driving for long stretches through desolate wilderness to check on a patient. This series presents enhanced episodes of "Dr. Oakley: Yukon Vet," which documents how the good doctor juggles being a full-time vet, wife and mom, and does so with a sense of humor and devotion.

This series, from the creators of the Emmy-winning "Deadliest Catch," follows four gold dredges and their eccentric and driven crews who risk their lives to find as much gold as possible before winter sets in and it's too dangerous to dive. The custom-built rigs, some barely seaworthy, include an 80-foot barge run by the most successful gold dredger in Nome, Alaska, and a modified skiff that seats only two people.

He's a fabricator and self-taught mechanic, whose techniques and design skills first endeared him to Rawlings and kick-started the partnership. At the end of Season 12, that partnership ended when Kaufman exited Gas Monkey, leaving Rawlings as the series' sole star.
