That familiar adage about old dogs and new tricks doesn’t apply to Cesar Millan.

A renowned canine behavior expert and the host of “Dog Whisperer With Cesar Millan,” he has revamped his show so that it more accurately portrays rehabilitation just in time for the eighth-season premiere tonight. The reality offering, which got its start on the National Geographic Channel, has found a new home on the network’s sister station, Nat Geo Wild.

Now fans can expect a more chatty and explanatory Millan. Instead of just saying a dog is dominant or submissive, he studies and explains such conclusions through their micro-expressions captured on video. Think “Lie to Me,” but without Tim Roth and his angry eyes and snooty British accent.

Millan, 42, also seems to be more compassionate and patient with befuddled owners. In the season opener, for instance, he gives dog owner Sandy Hill the benefit of the doubt when trying to help her and her two troubled Jack Russell terriers, Ruby and Jinx. The two can’t stop fighting each other, and Millan comes in and tries to bring peace to Hill’s home.

Unlike before, Millan also seems less interested in being right and more concerned with truly making owners and their pooches happy. Could it be that finally he is buckling under the pressure of guff and criticism from certain members of the veterinarian community? Or maybe the divorce from his wife of 16 years changed him? Maybe it’s a little bit of both.

Whatever the reason, “Dog Whisperer With Cesar Millan” is an old rover with a fresh makeover just begging for viewers’ love and attention.
