The Seventh Brother (1991)

A lost puppy adopted by a friendly colony of rabbits must find his way home before the cold winds of winter begin to blow in an animated tale of friendship and faith that aims to encourage healthy conversation between parent and child. When Tiny is separated from young Angie and her gentle grandfather, he soon begins to fear that he will never find his way back home. Soon adopted by a concerned family of rabbits and invited to live among them as one of the family, Tiny does his best to protect his siblings and settle in to his new home. As winter approaches Tiny begins to grow increasingly weak though, and when the struggling pup's friends band together to help him get back to his family Tiny soon learns that a little faith is enough to overcome any fear. ~ Jason Buchanan, Rovi
