In his nature
Though it’s in the nature of Golden retrievers to retrieve stuff, and Storm’s rescue was an act of instinct, the story of the hero dog became a sensation. Storm became a celebrity and was interviewed by local news stations.
Mark’s other dog, Sarah, was left out of the spotlight. Since it’s in the nature of Golden retrievers to retrieve anything they see, it’s no surprise that it was Storm who jumped into the water to save the fawn, though at first he didn’t even know what it was he was saving.
