Over 22 dangerous dogs are to be put down in a police crackdown on Merseyside.
The animals were on a 'hit list' of 42 animals assessed as being dangerous to the public.
Police said the owners had not adhered to conditions imposed by the courts when they were allowed to keep their dogs.
Two children and a pensioner have been killed on Merseyside after being attacked by dogs since January 2007.
Two of those deaths - five-year-old Ellie Lawrenson and four-year-old John Paul Massey - were killed by banned pit-bulls. The third was 79-year-old Clifford Clarke who was killed by a dog in his garden.
Chief Inspector Chris Gibson said:
"Despite the deaths of three people, there are still people within our communities who still see fit to breed these dangerous dogs despite the threat they pose ."
