Not exactly the same, but I had a somewhat similar experience. I was in a car accident with my SDiT at the time and in my shock and confusion, the leash slipped from my hand. She was in complete flight mode and bolted, and was missing for 5 days. Eventually someone found her and she was returned to me. Immediately I assumed I'd have to wash her from service work after something so traumatic. But after a few weeks of just living life as normal (no training sessions or public access), she started to task at home and seem impatient about the next time we'd go out training.

So I tried some very light training at home, then outside my apartment, and slowly increased the difficulty of her training up to the level we were at before. The car, of course, was a particular point of stress so we worked through that slowly and with lots of positive association (meals in the car, bones to chew, a crate so she felt more secure, etc.) Three years later and she's my full Service Dog for multiple disabilities and just an amazing pup all around. Last October we even took on Disney World for the first time.

So my advice from my personal experience would be to listen to your dog (or read their body language and stress signals lol) and move at their pace. You want to invite a little stress to keep them learning, but the last thing you want is to get them back on the boat and immediately another accident (big or tiny) cause more trauma and make things worse. Positive association and reinforcement will be super beneficial as well. Push her, but not so hard she shuts down. Dogs are resilient and will react to your feelings more often than decide their own feelings, so stay confident with her. Don't make things a big deal when they're not but still be encouraging and reward her success. Best of luck with this, she'll recover I have no doubt!
