It happened Saturday afternoon in Titusville.
The grandfather heard the child screaming from his backyard. He ran back and saw that his pit bull - lab mix had his granddaughter's head in its mouth.
The dog then also attacked him. He said he got cuts on his arms and lower leg and foot.
The girl was covered in blood when firefighters arrived.
She has puncture wounds along her hairline and cuts all over her leg.
Investigators said the grandparents have had the dog for two years, but the little girl's family has moved in with them. Authorities think this upset the dog.
The dog is now with animal control.
Thee girl and her grandfather are recovering at Parrish Medical Center but are expected to be OK.
