Her mother, Andrea Ellis, had cut her arm on some glass in her house near Columbus, Ohio, and her sister called 911 for help.
“She's bleeding all over the place!" her sister said in the call. "I need a paramedic!"
By coincidence, a cop on a routine call happened to be on the block. She called out to him for help.
"Sir, can you get me a paramedic?! I need a paramedic here!” she said.
But as the cop approached the house, events took a horrific turn. Cops said the family pet - a boxer-terrier mix named Patches, charged at the officer.
The cop fired his gun, and the bullet hit Andrea's four-year-old daughter, Ava, in the leg, shattering the bone.
"She asked me several times, 'Mommy, am I gonna die?'" Andrea Ellis told INSIDE EDITION.
Then a neighbor called 911. “My neighbor across the street had an officer at her door and she's screaming that he shot a child,” said the neighbor.
Police dashcam video shows the chaos in the immediate aftermath. Medics and cops descended on the house.
