Warning: Video contains strong language
After walking up hilly roads and discovering that their family home was destroyed, Jack Weaver and his brother-in-law Patrick Widen filmed the moment their nine-year-old Bernese mountain dog came running up to them.
Speaking to ABC, Weaver said: ""It was one of the greatest moments of my life."
"In the chaos of trying to escape, my parent's dog Izzy ran from them. My mom couldn't chase after her without risking her own life.
"They had to drive through walls of flames and across a burning wooden bridge to get to mark west springs road and to safety. They lost everything, but my mom was most devastated about leaving Izzy.
"My brother and husband were determined to try to get back to my parents property to see if by some miracle Izzy survived. They were turned away by police officers, but if you know my brother Jack or husband Patrick...neither one likes to be told no. They ended up hiking just under 3 miles to my parent's property.
"This video shows the last part of their hike up to my parent's house. It's a little long, but the ending is worth the watch.
