There aren’t dogs that were born knowing how to predict seizures. Most of them are trained by humans to be seizure response dogs, but not predict before one has begun. However, a few dogs have discovered how to predict them by themselves. For example, Ms. Stanley’s dogs predicted a seizure 30 minutes before it started, they started to bark and guide their owner to a safe place. Evidently, her dogs were trained to be seizure alert dogs, but they have developed another level of intuitive abilities. There is not relevant information to know how they do it, because the signs are not visible for humans.

Another similar situation is the case of a horse called Clever Hans. Hans could count, the owner could ask mathematical questions to the horse, and the horse would tap the correct answer. Eventually, a psychologist demonstrated that Hans wasn’t really resolving mathematical problems. Actually, Hans observed at the signs and movements that humas were doing unconsciously. He’d begin and stop tapping his foot when he could see it was time to start and stop tapping.

In conclusion, Hans and the dogs have similarities, they got their skills by themselves without human help. It's thought that those animals have an exceptional intelligence and they belong to another category. They decided to take actions to solve those problems. That is what intelligence is in us, we take actions using our intuitive and cognitive abilities to solve problems.
