In real life, the owner, Fielding Marshall, adopted Gonker to help through tough times after the sad passing of his infant daughter.
Gonker has Addison's disease, meaning his adrenal glands couldn’t produce enough hormones. And so, Fielding had to administer hormonal shots once a month or else the pup would slip into a coma.
Almost two weeks after Gonker’s injection, he got lost while hiking with Fielding. The owner searched tirelessly for his furry companion, fearing he would lose his life by missing his next injection which was due in two weeks.
Marshall hung posters all over his town, with local news covering the disappearance and several kind strangers giving leads of the dog’s possible location. Gonker was found 15 days later, alive and well, having trekked 178 kilometers.
