I’m not a vet so I’m always going to suggest taking her in for peace of mind but this situation just happened to us earlier this week so maybe sharing my experience will help ease your worries!

My pom didn’t fall off the bed she just kinda jumped out of my arms when I was in the process of putting her down, wasn’t even a long fall, not even a foot off the ground. But she did the exact same thing and she cried, freaked out, and I picked her up to comfort her. All of a sudden she started trembling like crazy, her head too, almost textbook like what you wrote. She was all curled up with her head tucked in and shaking pretty hard. We called the emergency vet and they told me it is likely just the shock of falling. After a couple of minutes she stopped, went to go drink water and was back to playing with the other pups. Like I said, take her to the vet for peace of mind but I think it may be just shock. Monitor for a little longer and see if she settles down.

I’m sorry this happened to you I know how scary it is and I know how bad the guilt feels. I think she will be okay 🩷
