On Harvest Moon Magical melody does your dog ever grow bigger? And when ?and how?

Question

PLease Hurry up this Harvest Moon game that i am talking about is for gamecube!

Answer 1

No, the dog never grows bigger. In fact, the dog doesn't do much of anything except get you a Musical Note when you get your friendship with the dog to 3 hearts. Nobody and nothing grows in the game (except your crops, and your baby becomes a toddler forever).

Answer 2

No, your dog doesn't grow. But as the other person said, you can get a note from it.
