A 2-year-old boy was flown to Johnson City Medical Center following an attack by a pit bull-mix dog about 1:10 p.m. Monday, authorities said.
The dog was shot and killed. The attack on the boy happened in the yard of a house at 4005 Afton Road, a 911 dispatcher said.
The dog was tied up, and the little boy apparently approached the animal before the attack, county Animal Control Director Justin House said.
Sheriff's deputies and Greene County-Greeneville Emergency Medical Services responded. The EMS treated the boy and called Wings Air Rescue to take him to the hospital, EMS Director Robert Sayne said.
The boy's wounds "were pretty substantial," Sayne said.
The Greene County Sheriff's Department is investigating the incident. The child's condition was not available this morning.
The dog will be sent to the state lab in Knoxville to test for rabies, House said.
