In addition to this, tell them to keep a diary detailing the events leading up to the seizure. If there are any contributing factors, they will show up when they're written down. Some of the things that can set them off are: over-excitement (excessive playing, running around, barking or maybe children chasing them around) Fear (thunderstorms, being woken up too quickly, threatening behaviour towards the dog) or any one of a dozen other events. They can even take a seizure in their sleep but it's important to try & determine a cause (if any) so that the problem can be eliminated & lessen the chance of it happening. They also need to keep a record of times & dates to show the frequency of how often it happens. All this info will be a big help to the vet when determining what drugs to give & the dosage. The most common treatment is with Phenobarb but maybe you have something better where you are.Our previous pet was epileptic. If he was not on the floor, we would move him there and clear the area of anything that he might hit and hurt himself. Then we would get down on the floor with him and hold him in a comforting way, not restrictive. We always felt he was frightened by what was happening or what had just happened. Watching for the potential of swallowing tongue is always prudent. Not much else you can do other than keep hazards out of the way and provide some comfort.
Also, it's important that they don't 'transmit' their anxiety to the dog. The best thing they can do is follow the above advice & let the dog come around in his own time. If the dog senses their anxiety, he will only become worse.
I've had 2 dogs that were epileptic. One was one of my Pugs who was born with it & one of our old Chihuahuas who took his first fit @ 15. He lived until he was 19 with a lot of TLC. Once you learn how to manage the problem, there is no reason why the dog shouldn't lead a normal happy life.
Please keep us posted re his progress.
