“last resort” (8 p.m., abc): Don’t let the submarine thriller “Last Resort” take a dive in the ratings. Fall’s best new drama returns with another tense episode in which an unknown force attacks the crew and puts Marcus (Andre Braugher) and Sam (Scott Speedman) on the defensive.
“hero dog awards” (8 p.m., hallmark): Apparently, not all dogs sit around for hours and scratch themselves. Some actually contribute to society. And so Kristin Chenoweth hosts the “American Humane Association Hero Dog Awards.” Among the honorees: a canine who served in Iraq, searching for explosives and weapons.
