Can You Name That Dog?

I've got one for you to figure out. What famous TV dog was rescued out of the trenches in France during world war one? A war dog kennel was bombed and the mother and five puppies survived. This little pup was only five days old and became one of the only two survivors in the end.
Corporal Lee Duncan took the two pups and named one after a tiny 1" tall French puppet. Hmmm...there's a clue. Duncan worked with these dogs and found out the kennel master in charge of the bombed kennel had been captured by the Americans. Duncan actually visited the kennel master in prison to find out more about this new breed and to let him know about the rescue.
After the war, Duncan took his pups back the the United States to his home in Los Angeles. During the long 15 day journey, the female pup became ill with distemper and finally died.
Duncan took his remaining puppy to dog shows. In 1922, The Novograph Pictures Company asked to film this dog in action.
He knew this dog was special and took him to every film studio he could find. He was always turned down, but would not give up.
Finally after much persistence, the soon to be famous dog got a scene in the movie, " Man From Hells River." Another clue!
This film was a hit and the dog was a sensation. This dog made 26 pictures for Warner Brothers and got 10,000 fan letters a week.
But, in 1932, this famous pup died expectantly, Oh,no! Thank God for the new litter and now the son of _______ took his place. Many people wanted these pups of this famous bloodline, but Duncan was selective as to who they went to.
In 1960, Duncan died, but the bloodline was passed on to a woman in Texas who spent her life training, breeding and caring for these dogs. There have been 10 generations so far.
Ok, now you have the scoop. This dog stared in a TV show from 1950-1955. We all loved this show and the dog. Who was this mystery dog?
