Some additional information...
“A 4-year-old boy was critically injured when he was mauled by a pit bull this morning in District Heights, authorities said.
The boy’s injuries were not considered life-threatening, but he was attacked on the face and sustained traumatic injury to one of his eyes, said Mark Brady, spokesman for the Prince George’s County Fire and Emergency Medical Services Department.”

FWIW
“The dog’s owner spoke by phone exclusively with 9NEWS NOW and wusa9.com. He insists the dog was simply playing with the boy, licking and nibbling on his face when the boy pulled away. The man says the boy’s only injury is a cut to his eyelid.”
