Angeline Mahal was mauled to death in her Cornwall Close home on May 20 last year.
After a 999 call at 1.12pm, armed police rushed to the scene and discovered Ms Mahal with serious injuries and two XL bullies which were safely secured in a separate room.
Ms Mahal, 50, received treatment but later died of her injuries.
Her son, 26-year-old Rainveer Mahal, has now been charged with failing to ensure the welfare of two XL bullies.
It is alleged that Mr Mahal allowed the two XL bullies, named Scarface and Bella, to suffer with conditions noted by the vet during an examination.
Mr Mahal is also charged with possession of a fighting dog, Scarface.
Mr Mahal, of no fixed address, appeared at Willesden Magistrates’ Court on Thursday (March 6).
The case was adjourned until a later date.
At the time of Ms Mahal’s death police said the two XL bullies at her home belonged to her and were registered in line with the new requirements after the dog breed was added to the banned list for England and Wales last year.
