Make the dog safe. Remove things in area that it can hurt itself on. If the dog is having multiple seizures, concurrently, find a 24 hour emergency vet. If the dog had one seizure, it should recover for the evening on its own to make it through the night without intervention. The vet will do some tests and prescribe some meds. It's at this point that CBD should be considered as a preventative.
Some people have tried CBD oil for dogs, Google that
