Beethoven's Treasure Tail (2014)

Beethoven the St. Bernard, leaves Hollywood after a doggone disaster of a movie shoot, and with his trainer Eddie, are heading home when they get stranded in a small coastal village. Beethoven befriends a local boy who has been trying to find a treasure hidden by the boy's pirate grandfather 200 years ago. They unite their persistence and flair against a grandmother who dislikes pets and modern day pirates, and end up by bringing together the whole town, and Eddie and the boy's widowed mother.
