Pitbull terriers are back in the news after the brutal mauling of a seven-year-old child.
Darnell Mikaere Minarapa-Brown was rushed to hospital, undergoing surgery after he was attacked by his uncle's dog.
He received nine puncture wounds to the face.
The attack has again sparked calls for tighter controls around dangerous dogs.

Story took a look at some rescued dogs in New Zealand to see whether they'd pass the UK's checklist.
