 What happened to you, boy? My new movie is based on the true story of a dog who treks hundreds of miles to find someone to love him and ends up showing the whole entire world how extraordinary he is. Come on, boy. Lead the way. Arthur's not alone. There are dogs and cats in shelters all across the country hoping to find their very own people. And just like Arthur, they have this incredible ability to be an amazing friend. All they need is someone like you to show them the way home.
