The attack happened at a home on Second Avenue on Tuesday afternoon.
Authorities believe the toddler was attacked by a pit bull inside her family home.
Officials say the child was in the care of a teenager at the time and somehow she wandered away and encountered the dog.
Another dog was also in the building and police are working to determine if both dogs went after the child.
The little girl was pronounced dead at University Hospital just before 7 p.m.
Police are waiting to get more answers, but the child's family is distraught.
The dogs have since been removed from the residence.
The prosecutor's office said the investigation is active and ongoing.
