According to Glendale Police they got a call of a dog bite from the family dog around 1:22 p.m. Monday. Officer Breeden with the Glendale Police Department described the dog as a pit bull.
It all happened near 67th Avenue and Mountain View Road.
8-year-old Xavier was passing by the home and heard the screaming, he ran over to the home and called 911.
"I heard somebody yelling animal and hurt," said Xavier.
The dog bit an 8-year-old boy on the arm and leg and a 13-year-old girl was bitten in her lower extremities.
Paramedics rushed both of the children to area hospitals in serious but non life-threatening condition. The 8-year-old was flown to Phoenix Children's Hospital.
Neighbors that live nearby say they know of the dog.
"My son and his daughter and I were walking their dog, and the dog literally came out of the house and attacked the dog and my son. And after that we're kind of leery about the dog because he's so out of control, you don't know what he is going to do," said a neighbor.
They now call Xavier a hero for calling 911.
"I told them something is going on at this house, and because everybody is yelling animal and somebody is hurt, and I want police and at least animal control here," he said.
Maricopa County Rabies and Animal Control are responding to the scene and plan to euthanize the pit bull immediately at the request of the family.
