HiCustomer

When I hear a client described an arched back like this, my first suspicion is back pain or neck pain. Shivering often is secondary to pain as well. Back or neck pain can be caused by muscle (or soft tissue) injury or a disc rupture.

Unfortunately, Corgis as a breed are prone to disc problems, so my hunch is that your girl may have a bulging or ruptured disc that is causing her some discomfort.

The other possibility for her behavior is stomach pian/discomfort. If she tenses her belly, this can cause the back to arch. Pancreatitis and kidney stones are a few of the things that can cause belly pain.

As a veterinarian, my next diagnostic step would be to take radiographs of your dog's abdomen and back. I would also carefully palpate her back and manipulate her neck to determine if I can elicit any pain. Subsequently, there are blood tests to check specifically for pancreatitis.

I would recommend having your veterinarian reassess your dog as soon as you are able. Please let me know what you find.
