Second seizure. What next?

[Nicky, Riley & Boris]

This morning Boris had a second seizure. It happened pretty much the same way as the first though as he ran to find me he didn't manage to get up onto my bed but collapsed at the side of it. This time Joe got bitten because I stupidly in my panic instructed him to move Boris to a safer spot. It lasted nearly three minutes and I then gave him a Valium enema followed by a Valium tab 15 mins later as per our vets instructions. It took a very short time for him to get up but he was agitated for about an hour after but then was back to normal.
Tomorrow I will call the vet but what I wanted to ask is what is best medical practice at this stage as I strongly suspect he has Epilepsy. I am so sad today as is Joe. We know the bite was a stupid mistake as Boris, who is the gentlest boy was totally unaware of what was happening. We just want to be able to lessen the worry of what may happen and if these horrible events can be prevented.

Sorry to read this.  I am sure you have read all of the advise on things to do that may shorten or lessen the severity of the seizure (ice on hind quarter, ice cream after seizure, etc.)

Most of the time the doctors will not be able to determine a cause.  Keeping a diary and recording everything may give you a hint as to what is causing the seizures.  Although it may not "jump" out at you.  We know that giving the Heartgard and the Frontline close together may cause a seizure in Mariner about 5 or 6 days later.  Also changes in the weather - probably related to barometric pressure have caused seizures.  We do follow the weather forecasts and slightly increase his medication in anticipation.  Also stress in the household. 

We have been lucky, having kept Mariner seizure free for over 4 and a half years.  We have had times when we thought he was going to have a seizure - that we prevented.  Pretty much by only sitting with him and holding him.  (Also giving him some ice cream - his favorite).

What feedback did you get from the vet?
