I was taught in college that if a dog has a seizure less than 4 times a year there is no point in putting them on meds. Also, dogs that have seizures shouldnt be exposed to certain anesthetics, it can actually trigger a seizure and kill them. That being said, your dog has about 6-12 seizures per year correct? He should be put on medication, the most common being Phenobarbitol. The siezures can be triggered by many things, nobody on this board can give you an accurate diagnosis. Please take him to the vet, it will save you alot of money in the long run, since the seizures can cause many problems.
