That's the thing, when you have an adult and a pup; the pups learn from the adult - both good things, and bad! I haven't raised a lone dog in literally decades. It's easier in some ways, more difficult in others.
In other words, you speak Sheltie? Well, at learn Arwenese!
Oh, my! What did the instructor say about that?
