Man's calm reaction as Wolf follows him for 10 minutes goes viral

A hiker in the US' Yellowstone National Park was trailed by a young black wolf for nearly 10 minutes, reports stated. Ignazio Zanin was walking the Lamar River Trail when the collared animal followed him and gradually inched closer. Zanin used bear spray to deter the wolf, which park officials said was appropriate given the wild predator's proximity, reports added.
