Along with several others, the Weavers were suddenly forced out of their homes when a wall of flames closed in on their northern California neighborhood. Frightened by the chaos, Izzy bolted and the family, unable to find their beloved pet, had to evacuate without her.
In the video, later shared by Beckyjean Widen, Weaver's sister, both men are seen walking up the road to the house.
"The anticipation is killing me," one of the men says. "The gate is still standing [but] I don't see the house… I had my hopes up."
After sharing a few expletives upon realizing the house was no more, the two marched on as they began to make the first calls for Izzy.
"Izzy!" Jack Weaver calls out as he whistles and claps in the hopes of getting the dog's attention.
Echoing Weaver, Widen also begins to call out.
"Izzy! Izzy!" Widen continues. "Izzzzzyy!"
And just as the two comment on a tractor that made it out of the fire unscathed, a welcome surprise occurs.
"Izzy's here!" Weaver yells out suddenly. "Izzy come here baby!"
Seconds before the footage cuts out, Widen belches out an "oh my god."
Speaking to AP, Weaver, who was filming the scene for his parents, recalled the moment when the joyous reunion took place.
"She was very happy to see us," Weaver, speaking about the 9-year-old Bernese Mountain Dog, told AP. "She's such a brave dog. She was panting a lot and clearly stressed, but she was not frantic or anything."
However, after finding Izzy, the next feat was contacting the family and revealing the good news. Though cell service was spotty due to towers being destroyed in the blaze, both men were finally able reach the family.
"She just lost it," Weaver said of his mother Katherine. "She went from being devastated about losing her home to the happiest person I've ever seen. I couldn't get home fast enough. She was really, really happy… she's still shaken up by the whole thing, but she's in much better spirits now that Izzy is at our house."
Later examined by a veterinarian, Izzy passed with flying colors. According to Weaver, the vet said the pup was likely protected "from the fire's intense heat by her thick fur coat."
"She didn't have a burn on her," Weaver told the Mother Nature Network. "It definitely lifted my family's spirits."
The northern California fires have scorched more than 200,000 acres and destroyed roughly 5,700 homes and buildings. At least 40 people have been killed since the wildfires began on October 8.
