Levy County Sheriff Bobby McCallum tells the Gainesville Sun that the attack occurred Thursday morning in Fanning Springs after the boy's father went to work.
McCallum says the boy was followed by the pit bulls when he went outside to play and that an aunt watching him didn't notice anything unusual.
Later, the aunt looked outside and saw the boy lying in the driveway.
The sheriff says the dogs were well cared for and had current shots. They were seized by Levy County Animal Control.
