My Shyla still hides sometimes. When we meet people or dogs who she doesn't trust, she literally vanishes. She's very good at doing it without anyone noticing. People who don't know me are not aware that I have a dog with me.
If I look around really hard, I sometimes catch a glimpse of her peeking out from behind a tree...
... or behind a boulder. I don't tell the scary people that she's there because I feel like I'd be giving away Shyla's secret strategy. It would scare her if everyone turned and looked at her.
Then, after the scary people and their dogs have left, I call her. She bursts out to sprint to me.
No matter what, I've got her back.
