The two stayed together all the way to the ending.

The loyalty of a dog is unrivalled. Dogs are unquestionably human’s best buddies since they are with you practically always in any situation.
This anecdote will show you just how a dog’s devotion manifests itself.
Daniel Hove, an Air Force soldier, didn’t stop working for his country even after retirement. Because of his expertise, he soon became Burnsville’s Assistant Fire Chief, and many firemen looked up to him.
Daniel’s daughter, Heather Nicoletti, stated, My father was someone his team truly depended on to invent, teach, instruct, and stay up with the current fire fighting method.
Unfortunately, he was forced into retirement as he suffered from pancreatic cancer. After knowing this terrible news, his family, colleagues, and community poured their affection for their adored vet and wished for his recovery.
Doctors said that he was diagnosed with pancreatic cancer in October 2011. In February of 2012, he had Whipple surgery, followed by chemotherapy which went on for a long time, Nicoletti explained.
The one who was mostly sad about Daniel’s condition was Gunner, his 11-year-old labrador.
His canine companion, who was similarly in his elderly years, was always at his bedside. Gunner was there while Daniel was fit, and he committed to being by his side throughout his cancer struggle.
Daniel valued his great desire to live and the unwavering support of his dear ones. It motivated him to keep battling.
Daniel and Gunner were always together in their earlier years; They were closest companions till death. The two were hunters, and they travelled a lot, Nicoletti recalled.
Eventually, Gunner started feeling ill as he was old.
Nothing was shocking for the family; they had anticipated it because Gunner was also an older dog.
When my father got irritated, Gunner became irritated. When my father got uncomfortable, Gunner also got uncomfortable. Both my father and the dog were unresponsive at a glance. We anticipated it as we observed how Gunner was going–he wasn’t roaming anymore, and his health was getting worse day by day, Nicoletti says.
Nicoletti felt it was time to bid farewell to their ever-faithful canine pet when she saw the swollen arms and lifeless body.
I dialled the number for the vet’s office where I used to serve. They hurried me in, and I hustled Gunner up to the doctor’s room, and then he was put to sleep. Only an hour and a half passed, and my father was dead as well, she recalled, recounting the events of that day.
The two friends, Daniel and Gunner, were united till their final moments.
To describe Gunner as a faithful dog is an insult; he goes far beyond. They were both fortunate to have found trustworthy companions.
Nicoletti stated that he didn’t understand what would’ve been more upsetting for Gunner. Putting him to sleep to stop his misery, or if you let him experience his dad’s death. They had a belief that they both would end up in the heavens together. We just didn’t think it would be together.
Being unable to see one’s death turned out to be a gift in disguise for both Gunner and Daniel. Neither of them had to cry as they watched the other go.
And anyways, Nicoletti was relieved that both her dad and his faithful companion had gone to their ultimate resting places peacefully.
