Hi Lester
My male started suffering from seizures at the age of 7. My vet did some bloodwork on him and diagnosed his seizures as idiopathic meaning no known cause. We had to wait 4 days for the blood test results to come back, so I insisted that we start Buddy on a course of phenobarb immediatly and if the blood tests showed differently, we would cease the phenobarb and deal with the issues at hand. He agreed as like you say, it is awful to watch your furbaby have seizures. What type of testing have they done and why has your vet not put her on some type of seizure control for the interim?
My suggestion to you is to go back your vet discuss the testing he wants to do, thyroid and brain scans are normal tests for canines having seizures, and ask about some type of seizure medication to use in the interim. Phenobarb is inexpensive and once the drug dose is established I found it worked well at keeping Buddy seizure free. Also I found it very helpful to keep a daily diary on Buddy logging activities, food, weather, anything unusual about his day,general disposition etc. This is a useful tool for your vet to see when trying to make a diagnosis. As well the diary may help you identify triggers for the seizures. One thing I have learned since is this, If your vet diagnosis her seizures as idiopathic (unknown cause) do not accept this as the final diagnosis, insist that more testing be done for an underlying cause.
