"They lost everything, but my mom was most devastated about leaving Izzy", Widen added on the Facebook post.
The Weaver family had returned to their home in Santa Rosa for the first time since a ferocious wildfire destroyed their Northern California neighborhood in the middle of the night, CBS reported.
"Izzy's here!" Jack Weaver calls, choking up with emotion.
The two men were recording the scene to show Jack and Beckyjean's parents and captured the heartwarming reunion. Overall, the multiple fires that started first on October 8 are responsible for the deaths of at least 40 people, making it the deadliest wildfire outbreak in the state's history.
"Izzy's here! Izzy! Izzy, come here, baby!"
The men hiked for miles to survey the damage and said they figured their beloved dog, Izzy, was killed.
"There's so much smoke I can't show you the view", he said in the video.
Weaver and Biden found that the house had been leveled, but Izzy, their Bernese Mountain dog, had been hiding in the ruins.
"She's such a fearless dog".
A veterinarian said Izzy was fine, likely insulated from the fire's intense heat by its thick fur coat. She was panting, and visibly stressed, but Izzy did not panic, Weaver said.
Despite sketchy cellphone service, Jack Weaver was finally able to get a hold of his mother.
And just when the thought she was gone. "She went from being devastated about losing her home to being the happiest person I've ever seen".
On Facebook, the shelter has been posting videos and pictures of the animals they take in, hoping to send word to their owners.
"It was one of the greatest moments of my life", he said.
'It's an unwieldy beast right now, ' said Dennis Rein, the information officer at the Sonoma County Fairgrounds in Santa Rosa.
Widen shared: "No singed hair, no burned paws".
At Sonoma County Animal Services, vets and assistants were caring for 64 cats and 44 dogs, almost all of them brought in from fire zones.
