‘Westminster’ focuses on dogs

Luged out? Can’t tell a triple axel from Jeanne Tripplehorn? Overwhelmed by medals and moguls?

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” (8 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.

Canine expert David Frei will help cover this year’s Westminster, his 17th show. He’ll be joined by veterinarian Dr. Debbye Turner (“The Early Show”) and entertainment reporter Jill Rappaport (“The Today Show”).

But tonight goes to the dogs. More than 2,600 four-legged entrants, representing 165 breeds, will compete within their categories and then vie for the ultimate title: best in show.

“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.”
