Molly-Mae Wotherspoon, aged six months, was attacked by a pit bull in October at the Daventry home of her mother Claire Riley.
Ms Riley and the baby's grandmother, Susan Aucott, have been charged with owning a dangerously out of control dog resulting in a death.
Ms Riley did not appear before Northampton magistrates due to illness.
The baby died as a result of blood loss from head wounds inflicted by an American pit bull following an attack at an address on Morning Star Road on 3 October.
The breed is prohibited for ownership under the 1991 Dangerous Dogs Act.
Ms Aucott, 55, of Alfred Street in Northampton, appeared before magistrates but did not not enter a plea.
She was remanded on bail and is due to appear at Northampton Crown Court on 7 October.
The magistrates hearing for Ms Riley, 22, whose address was given as West Cotton Close in Northampton, has yet to be arranged.
She was remanded on bail in her absence.
The grandmother of a baby girl who was killed by a banned breed of dog has had her case committed to crown court.
