Planet Earth: Dynasties, 8 PM on BBCA; 12:25 AM on BBCA:

This six-episode follow-up to the acclaimed first season provides more fresh insights into the secret lives of some of the most fascinating animals on Earth, over an extended period of time. The season premiere, “Puma,” opens in the wild and remote highlands of Patagonia, where a solitary mother puma called Rupestre strives to raise four cubs, her largest litter yet. Hunting to feed her young forces Rupestre to brave hostile natural forces like white-out blizzards in which winds approach 100 mph. Her more serious threats, though, come from other pumas.

Movie: Romance to the Rescue, 8 PM on HALL:

When Kyra (Andrea Brooks) meets Trevor (Nathan Witte), the new manager at the grocery store where she works, he checks off the boxes on her list for Mr. Right. When a well-meaning colleague discovers Trevor is a huge dog lover, he blurts out that Kyra has a welltrained dog, to which Trevor enthusiastically suggests she enter her pooch in their store’s upcoming canine competition. This poses a problem for Kyra, who has no such pet. A nearby animal shelter may hold the answer, though, in this new romantic comedy.
