The attack happened in Miramar on Wednesday morning. The baby, identified as Liana Valino, was at her grandmother’s home while her mother worked.
The Miramar Police Department said Valino was sitting in the bouncy chair in a bedroom when the dog fatally attacked her.
The animal was between 3 and 4 years old. It was removed from the home by Broward County Animal Care and Adoption Division, along with two other dogs.
It’s unclear whether the dog will be euthanized.
“She was the best thing to ever happen to me,” said the baby’s mother, Brenda Villasin. “We smiled every morning. She was my world.”
