Vincent from LOST
No, but I bet he filled Al’s shoes plenty of times. 
Actually, wasn’t Buck reincarnated as Lucky?
Benji was a TV dog?! Then Higgins and Moose tied for first all time forever.
Vincent may have made me cry twice during the run of LOST but he didn’t have to do much doggy “acting”.
Oh, and besides, that was not the original Vincent in the final scene of LOST if memory serves, anyhow.
Zeus and Apollo from Magnum P.I..
I alslo liked Freeway from Hart To Hart b/c my cousins had one just like him.
You know who was a good dog? Fry’s dog Seymour. wipes away a tear
Tie between Buck Bundy and Tralfaz.
Have to give props to the Frasier dog amd the Futurama dog.
But my all time favorite is Lou, the chihuahua from The Soup. He’s sooo cute, and I love the way he “awoooos” on command, and the little skits they put him in.
Indeed he was. That poor dog. Well the original incarnation of Buck was my favorite.
Mr. Bojangles from SNL’s Dog Show was a very fine dog. World’s calmest dog.
The linked video isn’t very fine (a jerky video taping of a TV screen) but isn’t unwatchable.
Triumph, the insult comic dog.
