SS- It's almost like that! She's actually yawning.
But she is basically training herself to yawn on command - she seems to know I like it when she yawns so if I stand in front of her, about 5 feet away for about 30 seconds, it's a pretty sure thing that she'll start yawning. Then, after each yawn she'll kinda look at me like "was that good?" and if I tell her "good girl!", she'll stop but if I'm silent, she'll keep going until I tell her it was a good one. She's so great.
