Apologies in advance for this one!!
I wonder if anyone has experienced anything similar with their male dog?

Tonight my terrier suddenly hit the floor and lay trembling and twitching briefly.  He then stood up but hobbled along and was shaking and twitching his head for about a minute then jumped into his bed and shook and twitched his head for about another minute.  Then back to normal.  I don't know what he was doing before he had this episode but I had just started to walk away from where he was.

This happend before about 18 months ago, when it happened then I shot him straight to the vet - nothing found.
Last time it happened he had been humping his bed, as he does, and I ran down the stairs and startled him.  The vet and I came to the conclusion that he had an erection and hurt himself as he jumped off the bed.
He is a small dog, about 6 kg, this may sound stupid but if plenty of blood is "elsewhere" in his body do you think that he may be sort of fainting?

I will ring the vet tomorrow to see if I should take him in but as it stands he's completely normal now

God knows what anyone would think if they checked my Google history tonight -some of the things I've come across whilst trying to find an answer to this one don't bare thinking about!

Does the information on this page ring any bells?    What breed/mix of terrier is he?

Hi, thank you for your reply. 
I honestly don't know what mix he is unfortunately, there could be a bit of everything in there.  He is 8 years old and raw fed.
I've had a quick look at your link and watched a couple of youtube videos of dogs having a seizure, my initial reaction would be to say no, I don't think what happened night was CECS but I will continue to google later when I have more time.
I have to say I have never heard of Spikes Disease before so thank you very much for the info, will definitely mention it to the vet
Thanks again

It could be a mild form of epilepsy -and unfortunately there is no test to detect epilepsy so afterwards the dog will appear 100 % normal again, blood tests and similar will be normal too. What I would do if I was you (and did when it happened to a dog of mine) would be to film the next episode, IF it happens again, and then show it to your vet. It's the only way your vet will be able to see what is going on.

Seizures can take on many forms. I am aware of a border collie owner whom has a bitch that, literally, just 'drops' and is out cold for 2 minutes (no shaking etc) and then bounces back to life like nothing has happened. This happens every few months and has been diagnosed as epilepsy.

>and unfortunately there is no test to detect epilepsy

My Vet informed me only a matter of days ago that Neurologists will now brain scan dogs, whom are suspected of having Epilepsy and once blood tests have ruled out everything else. She advised that the tests are very expensive and are not without risks.

Yes they will scan -but unless there is an obvious cause such as a tumour, it will still find nothing.

The Neurologists have a set formula now where suspected Epilepsy is concerned. They work on charts and look at the whole 'history' e.g blood tests, seizure types, frequency, age and breed of animals etc. She did give me a name but I have forgotten what she called it now! The specialists collate all this information before carrying out further investigations. My Vet (and I assume she knows what she is talking about) said that you can get a definite 'epilepsy' diagnosis now, once the specialists have ruled out everything else. However, she did advise that there are possible risks associated with the brain scan and that unless you are desperate for a definite diagnosis (e.g a breeder may wish to know 100%), then they may not be worth the risk involved to find out.

How did you get on?

Sorry have had probs with my iPad, vet examined and all normal, just a case of waiting to see if it happens again.
He's absolutely fine in himself so it's a waiting game
Thanks
Everyone for your thoughts

Are you insured would be my first question? If you are then I'd personally be getting a bit pro-active. So many basics can be ruled out or in, thyroid, cobalamin, blood sugar levels, eye test (the eyes can be an early indicator of many things) etc, etc. As others have said MRIs and associated tests will only show something if there is something to be seen, cost is around £2,000. Also if insured it can be very worthwhile seeking expertise beyond the realms of a general practice vet.

>just a case of waiting to see if it happens again.

Very true. It is worth writing it down when it happens. Time, date, what happened and for how long, how the dog was afterwards or even beforehand if you noted a difference in behaviour. It may be that it was a one off but if it wasn't, then all this kind of information will come in handy at a later date.

>Very true. It is worth writing it down when it happens. Time, date, what happened and for how long,

When my bitch first started this never occurred to me.  The first couple were far apart, so no medication advised.  When they got closer together, I recorded exact times and dates, and how long they lasted.  After a particularly bad one I took my information to the vet, who started phenobarb immediately.
