Btw dogs often do this to indicate they're playing/mean no harm :)
The yawn thing that someone else mentioned is also common. If they are displeased with you, you get a yawn. Like if you ask them to do something (sit, paw etc) too many times and they're bored of you, you'll get an exaggerated vocal yawn.
And the last one I'll mention, because it's so common in all dogs I've seen, is the shake. Directly after a tense situation, they shake, like they do when they're drying themselves. For example, if you're walking your dog and they encounter another dog that is larger, or a breed that they don't know or don't trust, they'll sometimes do a quick shake a few seconds after the encounter. I always reward the shake with a treat, to tell them "good dog, you kept your shit together in a stressful situation". A trainer told me to do that when I had a grey who had very bad social anxiety, and it really worked.
I see it occasionally between dogs when one is being stiff/dominant and the other yawns to kind of apologize and diffuse the situation.
Then again, I haven't worked much with sighthounds and they're basically a different species from other dogs, haha.
Either way, she's wonderful, and learned every trick I taught her in the first couple of months. She still knows them all 9 years later. She's learned a lot about me without my instruction, we just fit like a glove.
I don't have an exact count, but she knows at least 30 commands (some are for the same thing, like "wait for me" and "slow down"). I use natural language. I'm not sure how many other things she's picked up. I always tell her "be right back" if it's true, but I'm not sure if she understands it or not, because she's not an anxious dog.
She's never been that interested in food or toys. She's a farm dog. The best.
I wish they'd speed up that research on dog longevity. She's 9.
Sneezing is a way dogs say they want to play. That's adorable that she loves sneezing for you. [1]

I don't know if she trained us or I trained her, but she associated stopping doing something with a yawn.
Don't like petting? yawn and the human will stop.
Don't like that food? yawn and we will change it.
Don't like going to the veterinary? yawn - but that never worked.
I loved that dog.
The hard part is most humans can't connect their own angst with their environmental conditions!
I noticed while teaching her to "speak" that she would sneeze a lot, I guess it's kind of a reflex for her when she tries to speak. So I wondered, can I teach a dog to sneeze? And sure enough, after a bit of training, she will now sneeze on command.
