Evan Moss is a nine-year-old boy with epilepsy:

I have two dogs. One is Dinky and the other is Mindy. Dinky is our family dog and he really belongs to my sister, Aria. Mindy is my seizure dog.

 

Evan and Mindy have a lot of fun together, even though Mindy’s job is pretty serious:

Mindy barks when I have a seizure so my parents will know. When I have a seizure, my mom and dad give me medicine to help stop the seizure. People ask me a lot what it feels like but it’s hard to describe and sometimes I don’t remember having a seizure.
