A Great Dane is helping the Co Clare family of a three year-old girl with epilepsy to respond to her frequent seizures.
Charlie the dog can detect the onset of a seizure for Brianna Lynch 20 minutes before the start of the episode.
Brianna suffers from different forms of epileptic seizures, many of which happen at night.
When Charlie detects that Brianna is about to have a seizure he will hold her gently against a wall until someone comes to help her.
