That would also be my first thought Brainless ;) Especially if it is a recent thing.
Perhaps a quick checkup at the Vet would do no harm ;)
Once any medical prob's have been ruled out, then these are my (probably useless) :rolleyes: observations on yawns.
One of my dogs is also of the horizontal attitude to life sort, even guns going off, firework night and 4ft singing swinging reindeers don't upset his happy existance
but whenever I'm late feeding him, the manical yawning comes into play. He'll do it in my face, complete with tremouring head just to make his point. If my little minx who knows she's Alpha, gives him a hard time for any reason (she really doesn't need one):rolleyes: then he'll also do it to her. If we have a disagreement in the family, he'll also display it.
It's an appeasing behaviour IMO but also is done when he starts to get aggitated.
My bitch doesn't do it nearly as often and when she does, it's normally at me when I have to unclamp her teeth from his face.
I've had dogs in the past that didn't have such a happy start to their lifes, yet didn't yawn like him.
So in my limited experience of observing
my different dogs behaviour over the years, to me, it seems that the more Alpha they are in status, the less likely they are to yawn in any given situations. :)
No doubt there will be others who have had differing experiences.
