I remember some click-bait about similar. Others were asking the parents if they weren't afraid the pit bull would eat their baby. And one day, the dog acted oddly in the yard. He may have growled at the toddler girl in that story as he ran past her, and he went into battle with something in the yard. It was a snake. He nearly died protecting the toddler from the snake. They got him to the vet in time.
