Took Copper out visiting today to the local junkyard (we're friends with the owners).  She met lots of people and saw lots of big scary equipment, and did really well!
She has started jumping for attention, but we're working on stopping that.  She's learning 'stay' too.
This dog is so weird y'all.  I almost don't have to use commands with her.  (Of course, she's in a regression phase right now and isn't really minding them very well anyway.  Unless I have beef heart.  I'm told this is normal.)  But she's GLUED to my body language, constantly watching my face and hands, she's sooo attuned.  She's using context nearly entirely to figure out what I want and to do it over really paying attention to what I'm asking for.  Like I know she knows at least some of the commands, but she seems to be preferring to use context?
IE:  I haven't had to teach her stay as a command per se.  I just have been teaching her sit at the door, then I hold up my hand and look her in the eyes, and then I step through the door and invite her through.  I had to show her this exactly 5 times without a single "stay" ever uttered.  She also figured out load-in/load-out of the vehicle all on her own, just by watching me for cues and responding to the lightest touch of leash.  Tonight I sat her at the barn gate and had to go inside and do some stuff I didn't want company on.  So I shut it with her on the other side and asked her to sit nicely.  5 minutes later, I come out, and she's in exactly the same position, waiting for me attentively.
She's also becoming rather lap doggy and snuggly when she's not in landshark mode. She safely dozed whilst getting petted in Mom's lap for 20 minutes today and they both enjoyed the hell out of that. I have no idea how that's going to work when she's 40+ pounds... 
Fed her mealworms with the chickens, but her chicken-snaps are getting too close to chicken heads to be safe anymore, she's just getting too big.  ( I swear the puppy I woke up to this morning was bigger than the one I put to bed last night?) Probably going to put an end to shared treat times until she has more self control.
If anyone has mind games that working dogs love, please share!  I think I need to keep her brain working more to develop what appears to be great potential.
