It will take $15,000 to train “Hershey” to wake up a child when she stops breathing in her sleep, reports News Channel 5.

Maddie now understands that Hershey could save her life one day.

Maddie sometimes stops breathing. She suffers from sleep apnea, narcolepsy, and asthma.

“She like nibbles under my pillow and I was like, ‘Ohhh.’ She was telling me a sign that I was doing something,” Maddie said.
