There are a few differences between a Seizure Alert Dog and a Seizure Response Dog. The functions of each of these types of service dog is slightly different, which results in a tailored training process.
A Seizure Response Dog is trained to behave a certain way when a seizure occurs. This is usually a task such as pressing a medical alert button, retrieving a phone, or barking for help.
By contrast, a Seizure Alert Dog is trained to behave a certain way before the seizure ever happens, providing early warning to their handler that a seizure is imminent. With many types of seizures, time is of the essence to limit the amount of damage the body suffers, and with enough advance notice, some seizures can even be prevented by the administration of appropriate medications.
Ever versatile, a service dog tested for the correct temperament and drive can actually be trained to both indicate before a seizure occurs, as well as sound the alert when one is in progress. This means it is theoretically possible for the dog to be trained in both seizure alert and seizure response skills, depending upon what the owner needs. Naturally, this is a more intensive training process and typically requires more time with the trainer, as this requires the dog to be trained with two very distinct (and potentially life-saving) skills.
Both types of service dogs are amazing examples of the abilities of our canine companions. However, it is important to understand that seizure alert is not a task all dogs can learn. Due to the precarious situations of seizures, it is a possibility the service dog may never pick up on the seizures ahead of time. Though seizure alert training is complex and can be difficult, it is still possible and extremely helpful to those who require this type of assistance.
