I Did Not Make It Up.

In paragraph two of her review of
Susan Orlean’s New York Times bestseller, 
Rin Tin Tin: The Life and The Legend,
(Oct. 20, 2011, New York Times Sunday Book Review,)
writer Jennifer Schuessler made the suggestion that
Rinny may belong on Rushmore with George and the Tedster.

“Don’t let the book’s title fool you.
Calling Rin Tin Tin the story of a dog
is like calling Moby Dick the story of a whale.”
– Meredith Maran, The Boston Globe 

Rin Tin Tin first came to television in October, 1954.
There were 166 episodes filmed from 1954 to 1959.
