When we first see Moze, Aunt Meg's Golden Retriever, he's a pure Golden and I figure about 2-3 years old. He is one solid gold color and his face is as well. Watch the scene where the tornado is taking Jonah and the driver (Jo's competition) up. There's a brief scene where we see Jo's team watching from the truck. Moze is in the center and has a pure white, aged face of a Golden who is probably 12 years or older! Now maybe it's not an OLDER dog but it clearly is a different dog from the one they previously used at the beginning!
