Shazza, I'm sorry to hear that your little one has been having trouble.
As others have said, the first stop is the Tierspital. Hopefully you already have contacted them, but if not here is the info:

You are in good hands at the Tierspital.
They may suggest that you see the neurologist as a follow-up (he is based in Luzern IIRC, but takes appointments at the Tierspital) - if so, I highly recommend him.
Seizures can be caused by many different things - try to give the vet as comprehensive a description of what happened as possible to help him help your little one. Information such as:
-What was happening just before the event - were there any unusual movements (such as seeming to bat something away from the face), or pacing, or standing rigid, or staring?
-Describe what your dog was doing during the event - was there eye movement? If so, horizonal or vertical? How fast was the eye movement? Did the eyes roll backwards?
-Did your dog go into convulsions? If so, try to describe what kind - leg movement, etc.
-Did your dog's legs seem rigid or 'frozen'? For how long?
-Did your dog collapse onto the ground? Did he remain so?
-How long did the seizure last?
*** I know that it will have seemed to last a very long time, but this is usually only perception. Should another occur, try to time it. Keep record of each seizure - time of day, etc. Again, looking for patterns
-Did your dog lose consciousness? Did he appear to respond to you, or was he aware of your presence?
-Did your dog vomit?
-Did he urinate or defecate?
-Once the seizure passed, describe your dog's physical state - how wobbly, for how long, was your dog able to walk normally or did he display ataxia* ("drunken walking"), did he walk in circles or diagonally, or was he able to walk in a straight line?
-Is there any lingering after-effect to the eyes, is one or both squinting?
And, to help rule out poison related seizures- has your dog eaten anything unusual?
And given the holiday - were there any fireworks going off when your dog had the first seizure?
* Is your dog by any chance an older dog? If so, and if he displayed the ataxia, there is a possibliity of vestibular syndrome - which looks like a seizure but is in fact an inner-ear issue. Hence, the need to describe as best you can what happened before, during, and after.
Keeping good records, gathering information to try to establish patterns can be extremely helpful for your veterinarian. You might ask him if filming a seizure would be helpful. If so, it is often best to have a second person do so, as you are likely to be occupied with caring for your dog. And if you do film an event, be careful NOT to get the flash in your dog's eyes!!! But ask the vet first if this would be helpful in your dog's case, or not.
These are two websites with some very good information on seizures. They are both devoted to canine epilepsy, but have a lot of good info on seizures caused by other condition/factors. You might find the information helpful:

I have some experience with canine seizures - after much testing and backing-and-forthing we decided that my dog's seizures were likely due to FSME (tick born encephalitis), although we cannot say for certain and must remain open to other possibilities.
Should you need a symathetic ear or shoulder to cry on, feel free to PM me.
FIngers crossed, thumbs pressed for your little guy.
FYI, the German for seizure is Anfall.
