toy poodle with seizures

Question
Hi my boyfriend and I just got a 4 year old toy poodle from a friend.  He was fine the first three days we had him and then on the forth day he had a seizure where we found him on the floor very tense and shaking.  He tried walking and his legs just sprawled out and he couldn't move so we rushed him to the vet.  They did blood work and a urine analysis and found that he is perfectly healthy.  The previous owners said that he has been having them about once a week. But after his first with us he had two more within a 12 hour period.Today he had a small shaking episode and threw up a white foam.  The previous owners have taken him to the vet on a few occasions and their vet also said he is fine on the inside and cant explain the seizures.  We have never had to deal with anything like this and I am wondering if it sounds like he is getting worse.  I don't want one of these episodes to end with his death.  Do you know of any possibilities why he is having the seizures and why he he is having them more frequently.  When he has a seizure they start out of nowhere while he is laying down resting.  He doesn't urinate or have any accidents he just starts to drool and look around with a blank stare while he shakes and gets very tense.  Please let me know what you think about this and if you have any questions.  Thank  you for your time.

Hello Kaitlyn,
Unfortunally, Seizures are becomeing more frequent in Poodles.  I have a Silver boy who will have one about every 4 months or so and most times there is nothing that seems to bring them on.   He tends to get really clingy just before he has one as if he knows its coming.  When this happens, I sit with him on the floor and try to comfort him the best I can by talking to him and I usually say a little Prayer for him.
They tend to last around 5-8 minutes or so (thought those are some of the longest minutes of my life) and then he comes out of it, and after a couple of recooperation minutes, he acts as if nothing has happened.

With Seizures, there can be a number of things that can trigger them, but unfortunally unless the seizure happens right there in the Vets office, the tests will show that everything is normal.  Your dog has to be sezing for the bloodwork to show what is causing the seizure.

Seizures can be caused by Stress/High excitement, Improper nutrition, Medication, Trauma, Genetic history, Medical condition, etc.
It sounds to me like your dog has had a history of Seizures and maybe the stress of moving to a new home has caused them to increase in number and frequency.

One thing that would be helpful for you and your Vet is to keep a journal about what happens durning the Seizure.  Log information on;
What your dog was doing before the Seizure,
What he did during the Seizure (did he drool, growl, whine, bark, lose his bowels or bladder, throw-up, ets)
How long did it last,  How long was his recovery time, and can you think of anything that he might have been exposed to before the seizure (chemicals, household cleaning products, yard sprays, medication)

Your Vet may be able to prescribe Pheno Barbital (may be spelled wrong) or a similar drug to help keep the Seizures under control.  
The medication is controversial because the side-effects of the drug can sometimes be worse than the seizures, but in your dogs case, since he is suffering so many so frequently, it may be an option that you need to think about.
If your Vet hasn't suggested it yet, you may think about going with another Vet's opinion.
I would try just calling several Vets in your area, let them know whats going on and see what they have to say.

I'm sorry for what your dog is going through.  If you need some more advice or someone to talk to, please don't hesitate to contact me.
