Luged out? Can’t tell a triple axel from Jeanne Tripplehorn? Overwhelmed by medals and moguls? Does the sight of a cross-country ski race make you feel guilty about that Nordic Track machine that’s been sitting in your laundry room since 1998?

Perhaps you need a break from the Winter Olympics. Trade in some alpine skiing for strutting Affenpinschers, frisky corgis, Siberian huskies and standard schnauzers.

Yes, we’re talking about the 130th “Westminster Kennel Club Dog Show” (7 p.m., USA, concludes Tuesday). This is the 23rd consecutive year that USA has carried Westminster, the second-oldest, still-running sporting event in the United States. Only the Kentucky Derby is more venerable.

¢ What is this thing called love? Poets from Catullus to Cole Porter have been trying to define, describe and celebrate it. But that was so pre-21st century. To some, l’amour boils down to a formula, an Erlenmeyer flask full of pheromones or the spark resulting from a crossed connection in a jangled ganglion. In this spirit, the series “Naked Science” (8 p.m., National Geographic) reduces the pursuit of love to a show called “What’s Sexy?”

“Sexy” talks to neurologists and researchers who think they’re pretty close to figuring out the physical and chemical reactions that we call love. Says one: “The part of the brain that becomes active when you look at a photograph of your lover, it’s exactly the same region of the brain that becomes active when you feel the rush of cocaine.”
