Lily Simonton and Charlie.
KXAS - Diabetes can be especially tough to regulate in children, but a new four-legged friend is giving one North Texas family peace of mind.
Snack time is a treat for most 5-year-olds, but the break for food is essential for Lily Simonton.
Lily's blood sugar levels must be closely monitored, which can be a challenge for her mom and teachers.
But an extra set of eyes and nose is always nearby after the addition of Charlie, a British lab, who serves as a diabetic alert dog.
Charlie detects Lily's blood sugar levels through scent as they rise and fall.
Charlie alerts Lily's mother or teachers when her levels need checking, putting everyone at ease.
Even Lily knows that Charlie is more than a girl's best friend.
"He saves my life," she said.
