Jean the Vitagraph Dog was owned and trained by Larry Trimble. Jean started in films in 1910 and was the first US canine movie star. From what I can find, Trimble started at Vitagraph as a trainer, writer, actor, director and worked often with Florence Turner.Jean started in films the summer of 1910 when Trimble took his Vitagraph company to Maine. The oldest surviving film from this summer appears to be
Jean the Match-Maker. Trimble, Turner and Jean made 6 or 7 films that summer. Several survive.
Anyway..... Another film from 1910 titled
A Frontier Hero was produced by Edison and released that July. It also features a collie and the dog looks very similar to Jean. Maybe all collies look alike, but what a coincidence. The first Jean film wasn't released til August of 1910. Here are caps of each dog:

Did Trimble and Jean work for Edison that same year? Or is this a totally bizarre coincidence with two different dogs? The dog act is even the same (pretty much).
