The phrase "Little Horse’s Way Home!" is almost correct, but it depends on what you want to say.
If you mean to say that the little horse has a path or route to get home, you could say:
- "Little Horse’s Way Home!" — This means the way (path) that belongs to the little horse to get home. This is correct if you're showing the path of the little horse.
If you want to make it a sentence or a statement, you could say:
- "The Little Horse’s Way Home" — adding "The" at the start makes it clearer.
- Or, "The Little Horse’s Way Back Home" if you want to say the horse is going back home.
However, if you want to tell a story title or a phrase for a book, your original phrase is acceptable and understandable as it is!
