The Night Cry (1926)
Directed by Herman C. Raymaker

Rin Tin Tin .... Himself - a dog 
John Harron .... John Martin

Gayne Whitman .... Miguel Hernández 
Heinie Conklin .... Tony 
Don Alvarado .... Pedro 
Mary Louise Miller .... The Martin Baby

A giant condor is killing sheep and Rinty is unjustly accused and by the law of the range must be destroyed. Rinty's owner hides him from the other ranchers. The condor steals a child and Rinty tracks it to its lair and destroys the giant bird. All the stories of how Rin-Tin-Tin could really act are substantiated in this film. The scene when Rinty returns home not knowing why his owner is angry with him has to be our favorite.
