Greyhound Seizure ??

since she came out of it fine and its over with there really is nothing a vet could do at this point. and they probably wouldnt put her on anti-seizure meds with only one seizure. just be watchful for more. at her age there is a chance that there is actually a cause besides just being prone to them like some dogs. if she has another one then i would see a vet and get an exam and some tests run to make sure there isnt a cause that you should know about. also if she starts having them on a regular basis and the vet can't determine a reason for them, there are a few anti-seizures meds available to help control them. some dogs have been known to have just one or two in their lifetime for no apparent reason and never have one again, so at this point i wouldnt be too worried but i would keep an eye on her. as you might know multiple seizure (especially cluster seizures) can lead to brain damage. good luck and hope it doesnt happen again.
