The Cabinet minister announced that she has commissioned “urgent advice” on outlawing the breed after she highlighted an “appalling” attack on an 11-year-old girl in Birmingham.
West Midlands Police were investigating after the girl and two men who intervened were injured in the incident in the Bordesley Green area on Saturday.
“This is appalling. The American XL Bully is a clear and lethal danger to our communities, particularly to children,” Ms Braverman wrote on social media.
“We can’t go on like this.
“I have commissioned urgent advice on banning them.”
The advice was commissioned last week, an adviser said, with it being the Department for Environment, Food and Rural Affairs’ responsibility to add the breed to the banned list.
