Kathy Griffin lords her 2007 Emmy win over Cesar Milan on a special episode of “The Dog Whisperer” (8 p.m., National Geographic). The star of “My Life on the D-List” invites Milan to her home to help her get her two dogs, Chance and LuLu, under control. She even bets Milan her Emmy trophy that he can’t train her dogs to work on a treadmill. Guess who loses?

For all of her outrageous outbursts, Griffin is hardly the oddest client on tonight’s episode. One woman, who claims to make a living as an “animal communicator,” can’t control her two vicious dobermans. She can tell you what her dogs are “thinking,” even while they are lunging viciously in your direction. Milan, no stranger to the New Age sensitivities of Hollywood denizens, appears to take her claims with a grain of salt. Or is that a crystal of salt?

¢ With Discovery Channel’s annual “Shark Week” just two nights away, rival cable network National Geographic gets into the act with “Sharkville” (9 p.m.), an hour-long special about hunting great whites off the coast of South Africa.

¢ At the risk of making this another all-critter column, “Extraordinary Animals” (8:30 p.m., Animal Planet) profiles a primate known as a Chimpan-Genius, a chimpanzee with a gift for memorization that leaves human competitors in the dust.

¢ While we’re on the subject of questionable human intelligence, E! offers us a brand new “True Hollywood Story” (7 p.m., E!) profile of Britney Spears.

¢ By apparent coincidence, two cable networks offer viewers a three-film blaxploitation film festival. Fred Williamson stars in the 1973 gangster shocker “Black Caesar” (11 p.m., IFC), directed by cult favorite Larry Cohen.

Turner Classic Movies offers two films from the lesser-known director Jamaa Fanaka, including “Emma Mae” (1 a.m. Saturday, TCM), a 1976 film about a country girl gone astray on L.A.’s mean streets and the 1979 boxer-in-prison drama “Penitentiary” (2:45 a.m., TCM). “Penitentiary” would inspire two sequels, and “Emma Mae” was also released as “Black Sister’s Revenge.”
