Chili, N.Y.-- Devyn Pereira was born with Angelman's Syndrome. It is a rare form of autism that includes severe epileptic seizures.
People in Chili and Gates responded when Devyn's family held fundraisers to get a service dog for Devyn. They raised $16,000.
The Pereira's welcomed 2-year-old Hannah into their home and hearts. She has changed Devyn's life and, at times, saved her life.
Hannah senses when the five-year-old is about to have a seizure and even wakes up Devyn's mother to let her know the child is in trouble.
The sheep dog has also helped Devyn learn to walk. Before the service dog arrived, Devyn had to use a wheelchair. Now, she walks with Hannah attached at her hip by a tether.
Up until now, Hannah has been allowed to go to pre-school with Devyn in Gates. The service dog rides the bus or van and spends the day in class.
