This Service Dog Knew Something Was Wrong Before Anyone Else-and Refused To Relax
Service dogs are incredible, and they do so many essential jobs for the humans they work for. With their ability to see or smell things more acutely than humans, their life-changing care alerts people to issues well before any signs or symptoms can be seen by the human eye. Their focus and dedication are so moving to see!
In this video, we meet a service dog who works with a young girl. In this moment, he knew something was wrong before anyone else, and he refused to relax. His strong sense of responsibility and persistence are impressive and heartwarming. Take a look!
@kennedyst1djourney He's not being nosy… Kona alerted quietly before we ever checked her blood sugar. Now he waits… watching every move… because he knows what comes next- 73= cheese! #type1diabetes#servicedog#diabeticalertdog#diabetes#autoimmunedisease
I Don't Wanna Stop - The Bamboos
On April 29, TikToker @kennedyst1djourney shared a video of a young lady named Kennedy and her service dog Kona. Kona appears to be a black-and-white Bernedoodle or another Poodle mix, and while he's incredibly cute, he's also hard at work. He's a service dog for Kennedy, who has Type 1 diabetes, and he's been trained specifically to keep Kennedy safe.
In this video, we see exactly how Kona works when he detects a change in his human's blood sugar, before anyone else knows. Hovering close to his mom and Kennedy, the incredible service dog refuses to relax, standing totally focused and on guard while Kennedy checks her blood sugar. When the reading is confirmed by the finger poke, he stands to wag his tail-he was right again!
In the comments, people praised Kona for his incredible work alerting to the blood sugar change.
One person wrote, "He's not waiting to see if he gets cheese. He's just waiting for you to realize, hahaha."
Another shared, "He doesn't ever miss! You might as well give him the cheese upfront!"
Someone else added, "I just love watching him work! His face tells it all: 'I did good?'"
Other comments included, "Kona is always right!" "Good job, Kona," "He gets all the cheeses he wants," "Love these guys," "Kona the king," and "OMG, that face. Good boy!"

How Service Dogs Detect Blood Sugar Changes Before Humans Notice Symptoms
Kona is such an incredible dog, and he's doing a very important job with his favorite human. It's really amazing what some pups can do, like Kona, who can detect a drop in blood sugar. But how exactly do they do that? Well, that's very interesting, too.
According to the American Kennel Club, dogs trained as lifesaving diabetic alert dogs can detect chemical changes and alert someone to them. The club explains that dogs like Kona can smell subtle chemicals released when their human's blood sugar is either too high or too low. Humans don't have that ability, but a dog can detect that change in a person's sweat or breath.
From there, the service dog does what we see Kona do in the video clip. They'll alert someone who knows what to watch for, like their human or a family member, using "specially trained behaviors, such as pawing, licking, vocalizing, or even fetching a blood glucose meter."
These specially trained dogs can detect these changes, often much sooner than a wearable device can, or before their person feels any physical symptoms from a change in blood sugar. It's a literal lifesaver, and we're so thankful for Kona and other dogs like him doing this incredible work.
