Two dogs starved to death after they were entombed in a boarded up house.
The door to the bedroom where they lived without food or water for up to three months was wired to a bannister so it could not be opened.
And when an RSPCA inspector finally broke in to discover the corpses of Staffordshire bull terriers Buster and Roxy, he found teeth and claw marks on the walls - made by the desperate animals.
Now their cruel owner has been locked up himself....for 23 weeks.
Jason Proctor, 30, of Laburnum Street, Layton, admitted causing the animals unnecessary suffering.
As well as jail he was also banned from keeping any animal for the next 10 years by Blackpool Magistrates.
Jonathon Fail, prosecuting for the RSPCA, said the dogs were found in a first floor room of a house in Adelaide Street where Proctor had been staying for a short time.
Proctor returned to the house one day and found contractors boarding the windows and doors up because it was being repossessed.
Proctor was allowed in once to collect some belongings but he left the dogs behind where over the months they lost half their bodyweight.
They suffered starvation and dehydration.
The dogs corpses were only found when a man was sent in to tidy the place up before it was put on sale. He alerted police and the RSPCA.
Thr prosecutor said: “The dogs were found one on top of the other. Their bones were clearly visible because they had lost so much weight. One of them had fungus in his mouth and eyes.
“The door had been wired to make sure it would not open and the scratch marks showed how desperate they were to get out.
“They had been suffering like this for a minimum of three months.”
Steven Townley, defending, said Proctor had been taken by surprise when the house he had been looking after was re-possessed.
He said: “He did ask if he could go back in once and left the dogs. Foolishly he did not contact the authorities.
“The men who boarded up the house were aggressive towards him and he feared for his safety.”
