This is the best summary I could come up with:
A boy is being treated in hospital after being bitten in the head by a dog, believed to be an XL bully.
The eight-year-old was attacked in a communal area of flats near Wadham Road, Bootle at about 17:20 GMT on Saturday, Merseyside Police said.
The pair were detained on suspicion of being a person in charge of a dog dangerously out of control and causing injury.
Det Insp Gary Stratton, from Merseyside Police, said: "I want to reassure people that [the boy] is receiving the best possible care and treatment for his injuries, which are described as life-changing."
New rules for owning American XL bully dogs have recently come into force in England and Wales, and will be implemented in Scotland later this year.
Det Insp Stratton said: "We have seized the dog and extensive efforts are underway to establish exactly what happened.
