Luke, who's 7 years old, has type 1 diabetes, which means his body cannot properly control his blood sugar levels. To keep within a normal range, he requires frequent monitoring.
His mother, Dorrie Nuttall, said receiving that diagnosis was when everything changed for them.
"The doctor told us what we needed to do to take care of him," she told The Dodo. "We started researching everything that we could find to help him. We got him all the equipment to monitor him, but we wanted something to help us even more."
That's when they started researching diabetes detection dogs.
