What causes dogs to have seizers and how can u stop them from happening?

The seizures have different causes, and are very scary when they happen. In some cases, a vet can prescribe a medicine to stop them. Otherwise, there isn't much you can do.

My dog also has seizures. My vet prescribed phenobarbitol, same like humans take, his seizures aren't occurring on a regular basis, but more often than we would like. The medication which we keep on hand works really well. Only your vet can determine what causes the seizures in your dog, good luck with him.
