Its pretty old animated movie where a guy finds three doors underground.
Behind the doors are three different size dogs guarding money. One was guarding copper coins second was guarding silver coins and the third was guarding gold coin. Not shure but i remember the guy becoming friends with the dogs and having the money.
Cant remember anything else.
This is probably an animated movie about the fairytale ‘The Tinderbox’ of Hans Christian Andersen. From Wikipedia I found this movie which was originally in German, but the BBC purchased it and put it in their series “Tales From Europe” and dubbed it.
