Kyle Burgess was out on a hiking tour in Provo, Utah, when he spotted what looked like a tiny puppy up ahead.
Alone in the middle of the woods, the poor little dog had clearly been abandoned. Or so he thought, until he got closer and realised his life-threatening mistake.
Chased by a puma
Kyle approached the puppy, only to be faced with a very angry mother puma, who jumped out of the surrounding woodland to defend her cub.
The puppy, it turned out, wasn't a puppy at all! It was a puma cub, who was exploring the area while his protective mother kept a watchful eye nearby.
Fearing for her cub's safety, the adult puma began chasing the panicked hiker, who managed to film the 6 terrifying minutes on camera.
A narrow escape
It seems no amount of shouting could deter the defensive adult puma, who was fiercely determined to move the hiker away from her baby.
The video, which has now been viewed a million times on Instagram, even shows her rising up on her hind legs to scare Kyle away.
Thankfully, she eventually decides the time has come to move on, disappearing without a trace.
