Alligator Scarf

This movie I had when I was little, a dog who lived on a farm with his mother and brothers and sisters. Then the little brothers and sisters dog napped and oldest goes to their search itself. The older the red scarf with white polka dots on it in most if not all of the film. A scene I remember is one of the dogs was near a lake with an alligator and his big dog saved before the alligator got him. Please help!

Is this an animated film?

the dog that I know this is a farm Old Yeller

uhhh. Old Yeller? Bengi? Which type of dog?
Beethoven was it? Rin Tin Tin? k-nine? Turner and Hooch?
