Task advice: PTSD edition

Tl;dr How did yall train PTSD/Panic detection?

Hello! Can anyone give us some advice or alternate techniques on how to train early detection?

And, does anyone have their dog trained to help ground through dissociations?

I’d like Gilly (6yo FS black English lab) to try and detect an ptsd/dissociative episode or panic attack before it happens. Does anyone know how to actually do this? Right now she just knows how to interrupt and mitigate or stop an episode.

My trainer said that, since I have very few natural visual queues (it’s hard to visually see when an episode is starting), that I should be trying to assign a motion to the beginning of the panic feeling (starting to feel anxious and needing to deep breathe, so tap thigh etc.).

Thoughts? Thanks again!
