What to Watch Friday, Sept. 19

'Dog Whisperer'
(9PM, NGC) 100th episode
It's a dog day evening on this special episode of 'Whisperer,' which finds Cesar inviting more than 100 of his past pooch guests and their owners to a party to celebrate his 100th episode.

Complete with red carpet (lined with fire hydrants), the soiree marks a successful dog run in which the trainer has rehabbed more than 300 dogs and 500 owners (in more than 100 cities), curing the canines of aggression, fear and out-of-control behavior and empowering their owners with skills to live happily with man's best friend.

And as a thank you for Cesar's animal magnetism, his party guests have a doggone good surprise for him: An appearance by his childhood hero, Lassie.
