Amber Laudicina was training her service dog, Koda, for medical conditions in a supermarket, when all of a sudden training snapped into reality as Amber suffered a seizure.

The 36 year old from Winston-Salem, North Carolina, was acclimatising 10-month-old puppy Koda to what they might come across in a real-life situation, like being well-behaved in a store but then the training kicked up a notch.

During the session, Koda began to disobey commands and bark at Amber which she credited to Koda still being young and in training.

She sat on the floor to get a better understanding as to whether Koda was misbehaving or whether there was something bigger at play.

At that point, Amber dissociated from herself and slipped into a seizure and Koda stepped into action and began to alert others to Amber's state.

An employee from the store was able to tend to Amber; keeping her warm and in a position where harm could not be done to herself and helped calm Koda down in the process.

All of this was captured on camera in a rare instance as seizures cannot be predicted, thus this was an example where people can see the need and importance of training and living with service dogs for seizure and epilepsy.

Amber said: "I had no idea until later that night that my cell phone was still recording and recorded the entire heroic actions that this manager showed remaining calm by helping and keeping me safe and assuring my service dog did a great job.

"My service dog is not a seizure alert dog, or at least wasn't until now, as I rarely have seizures, he is trained for other serious medical conditions.

"He did everything he was trained to do in that video even though he was caught on his leash.

"My service dog program/trainer couldn't be more proud considering my dog is only 10 months old and did this and the program is 2 years long.

"You cannot train a dog to detect seizures, they either do or they don't."
