But, by taking a general obedience class, she will have those basics down early.
Let me think about what else you can do on your own while waiting, that will give her a good foundation...
Well, you can still make sure that she's around as many people as you can manage. Letting her get pet a lot, etc.
Also, handle her in various ways each day. Run your hands down her legs, rub her tummy, her feet, etc. You never can tell when a child, or an elderly person, will do something unexpected, touch-wise, and if she's already used to it she won't startle, be annoyed, etc.
I'd still expose her to as many things as you can. Things dropping, starting quiet and working up to louder, maybe with a treat bribe to show her that it's okay. Loud radio, turning up the sound on your computer sometimes, when she's nearby, etc.
Maybe a whistle that you could blow quietly across the yard and work up to louder...that's great just to get her used to another loud sound, but also if you guys are visiting a school.
I know that she's not a fan, but desensitizing to the car when you don't have to go anywhere would be time well spent.
You guys walking them is a good thing.
When you think that she's ready, I'd start to lay a light cover over her while she rests, then heavier ones, and then sew her a mock cape to try on for a few minutes at a time, working up to longer, to simulate whatever she will be 'dressed' in when she works.
Also, any other gear that she might wear. You've got the leash and collar covered, but will she wear a harness at any time?
The problem with harnesses, is that they need to fit just so, and pups grow out of them very quickly. But, definitely before she's 1, if she'll ever wear one.
Also, bathing. I'm pretty sure that she will get baths when she visits homes and such, so you will want to come up with a routine for a home bath that she can learn fairly early, just as dogs who are shown do.
In the beginning, a nice, warm water massage might appeal to her. You can even skip the soap the first couple of times, or find a tearless one.
Have you chosen a shampoo yet? Unlike regular groomings, there's no telling how many quick baths she might get at any given time. Because of that, I'd go for a very mild shampoo, and maybe one with a built-in conditioner.
There are so many little things. Some are important for future interactions with other people, and some will just make both of your lives easier once she's grown. Enjoying her baths, for example, keep both of you from starting a day badly.
Good luck with whatever foundation building exercises that you can think of!
