Job: To respond to their handler’s seizures via trained tasks. The dog may retrieve medication, utilize deep pressure stimulation to end a seizure early, fetch a nearby person to help or call 911. Other trained tasks are common as well.
Handler: May or may not show signs of physical disability.
Gear: Typically no special gear required.
Notes: Seizure Alert Dogs fall under this category. Please keep in mind that you cannot train a Seizure Response Dog to alert to seizures — it must be something the dog comes to do naturally via association with their human partner and an intuitive nature.
