Country music fans may have a blast when they see a show on Blake Shelton's "Doing It To Country Songs" tour, but little do they know that they're missing out on arguably the best (and cutest!) part of the entire tour, who stays hidden backstage.

That'd be Jazz, the adorable German shepherd of Shelton's opening act (and former "The Voice" mentee from 2012), RaeLynn. In addition to being the sweetest member of Shelton and RaeLynn's tour squad, Jazz has a very important job to do.

RaeLynn has type 1 diabetes, meaning her body doesn't produce enough insulin, the hormone needed to move glucose from the bloodstream to the rest of her body's cells for energy. This means RaeLynn is at risk of having glucose build up in her bloodstream, which can cause life-threatening complications, according to Mayo Clinic.

That's where Jazz comes in: He's a service dog who has been trained to detect (read: smell) changes in the singer's blood sugar levels. If he smells any sudden shifts, he alerts her — and will even wake her up in the middle of the night if necessary.

Because Jazz is such an integral part of helping RaeLynn manage her diabetes, he goes everywhere she goes, including tour stops and press events.

"It's cool to know that a dog is so loyal to you," she told People. "He is loyal to another level. He never lets me out of sight."

Jazz you're the reason Diabetes isn't too bad to have. #servicedog #myboy

As is the case for most people who have type 1 diabetes, the 22-year-old country singer was diagnosed young — at age 12 — so she's had to learn how to deal with it while she balances her demanding career. Being on tour can make it especially difficult to keep her blood sugar levels in check.

"I always check my sugar every morning, and I make sure to exercise because it makes me feel better," RaeLynn told Heathline. "I always check before I go on stage. If my BG (blood glucose) is 80 or lower, I usually eat something to make sure my sugar won't go low while I'm out there. My tour manager always keeps orange juice on the stage for me, so in case anything happens I can take a sip of it."

And faithful companion Jazz is always there to keep an eye out for any warning signs, too. Service dogs like Jazz are a common way to help diabetes patients manage their blood sugar levels. The fact that they're great cuddlers is just an added bonus!

Cuddles before bed. ❤️🐶❤️🐶

Her beloved pup (and literal lifesaver) can lighten up any room, RaeLynn told People. We don't doubt that — just look at that face!

Tour headliner Blake Shelton also approves of their unofficial tour mascot: RaeLynn told People that Shelton adores Jazz and can't believe how much smarter the German shepherd is compared to his own dog.
