An 11-year-old boy was recovering Monday after being bitten on the head by a dog.

Officials said the incident happened at a home in the 1500 block of Hillside Forest Drive in the Greatwood subdivision at 4:20 p.m. Sunday.

The Fort Bend County Sheriff's Office said the boy was playing with the family pet, a Boerboel, in the family's living room when the dog attacked him.

The boy was rushed to Memorial Hermann Hospital by a medical helicopter in fair condition. He is expected to recover.

The dog is a South African mastiff breed and weighs about 170 pounds, investigators said. It was killed to stop the attack, investigators said.
