Two women will be sentenced today after their dog savaged a pensioner to death.
Retired hospital porter Clifford Clarke, 79, was attacked in his garden in Liverpool after he opened his back door as he cooked a meal.
The Presa Canario dog had earlier escaped from the garden of his next door neighbour.
Neighbours had reported seeing the dog behaving dangerously and one of them called the police when he heard screaming coming from Mr Clarke's house in Richard Kelly Close, Norris Green.
The neighbour was horrified when he saw the pensioner on the floor being dragged and mauled by the dog.
Armed police arrived and shot the dog dead.
Mr Clarke was pronounced dead shortly afterwards in hospital.
Tests showed that the dog, known as Charlie, had not been fed or watered adequately for several hours before the attack last May.
Last month, Hayley Sulley, 30, of Richard Kelly Close, and Della Woods, 29, of Swallowhurst Crescent, Norris Green, pleaded guilty to an offence under the Dangerous Dogs Act of allowing a dog to enter a place where it was not allowed to be and where it injured a person.
The pair also admitted three offences of causing unnecessary suffering to a dog.
The Presa Canario, which originated in Spain's Canary Islands, is renowned as a large powerful breed but is not banned in the UK.
Sentencing takes place at Liverpool Crown Court.
