Last month, Dee Gallant, a Vancouver Island resident, and her eight-year-old husky retriever Murphy went to a local logging trail just outside of Duncan, British Columbia, for their regular evening walk, Global News Canada reported on Friday.
Gallant told Global News Canada that she and her companion were faced with a threatening cougar that stood 50 feet ahead, maintaining a solid stare.
In hopes of intimidating it, Gallant waved her arms and yelled at the animal as it slowly made its way towards her and Murphy.
Fortunately, Gallant had her phone handy, and in the heat of the moment, she pulled out her large music library and blasted the classic track to scare it off.
About the song, Gallant said: "I thought it was perfect because it gives him the message that I want to send, and it's a really intimidating-sounding song.
"I immediately put it on and I held it up high in the air... As soon as he heard the first note, he bolted. He was just gone."
Gallant kept the song on loop for the rest of her hike, making sure to stay in the middle of the road and keeping Murphy close.
When asked what she would say to the members of Metallica, Gallant told Global News Canada: "I would definitely give them all a big hug and thank them for saving my life."
