Emotional trauma can cause a seizure-like syndrome, much like post-traumatic stress syndrome.
Are you sure that Dingo was actually having seizures? Other problems, such as severe anxiety attacks, and Syncope (fainting due to heart disease), can mimic seizures.
Seizures can be caused by many pre-existing conditions including: metabolic diseases, infectious diseases, brain masses, head trauma, toxins and chemicals, and idiopathic causes, and others.
If your dog has a seizure disorder from one of the causes I have listed above, the seizures can be brought on by changes in the environment such as storms, in susceptible individuals.
It is important to have Dingo examined and tested to establish if she does have a seizure disorder, or heart disease, etc., and if she does have a seizure disorder, it would be best to find out what the pre-existing cause is, and treat it appropriately, if possible.
For Dingo's own good she should probably be treated for the seizures and/or the anxiety. Many seizure medications also do help with anxiety.
