Before my time trivia question.

Hi In answer to the question ! Rusty was rin tin tins owner in the series . The dogs were three I THINK dogs if I remember right that played the dog, one would do all of the running and jumping parts ,another would do close ups. another would do all of the extra stunts. But all dogs were well trained and very easy to work with. bEAUTIFUL DOGS!! Take care Mary

Rin Tin Tin was 'owned' by Corporal Rusty played by Lee Eaker....and every time there was danger requiring quick canine action, he would always yell "Yooooooo Rinty!!" and then you KNEW that some ne'er do well was in for a mauling.

In support of Rusty being the owner, there was an episode on recently in which Rusty moved away to live with an old woman said to be his long-lost wealthy grandmother. Rinny boarded the stagecoach with Rusty, with the post's troops saying farewell to them both, and they lived together in Grandma's mansion. (I didn't sit through the ending, but I assume the reunion fell through and Rusty and Rinny returned to the post.)
