The breed of dog in the attack.
Update March 15: The Island Packet writes that the dog was euthanized following the attack on the child and the owner saying he no longer wanted the animal.
First reporting: A St. Helena Island toddler was badly mauled by a family's bull mastiff on Wednesday — I'll point you to WTOC 11's report.
Relatedly, in February of 2011 there was a string of dog maulings in Beaufort.
