I loved these old cartoons as a kid and still watch them on youtube. For some reason however this one has always stuck with me as an unpleasant memory. There used to be a rule in Hollywood passed by the Hays censorship office that evil should NEVER win out in a movie. Apparently this one slipped by them. I know its only a cartoon but it bothered me that evil dog got away with so many things form letting a burglar rob his loving masters house to trying to kill that poor little dog in the end and to top it all off that heroic cat who saw him for what he was got the bad treatment and justice didn't triumph in the end.
