A couple who left a Labrador puppy with a broken back and bruised ribs could be facing jail.

'Cash' was mistreated by his owners - Anthony Thomas, 28, of Batman Close, and Krystle Stanislaus, 19, of Banstead Court, Westway, both in Shepherd's Bush - between April 6 and June 7 last year.

At West London Magistrates' Court on Wednesday last week, Thomas and Stanislaus pleaded guilty to causing the dog mental and physical suffering, by failing to protect him from receiving deliberate injuries; and failing to take him to a vet.

On June 5, police officers went to Stanislaus's house, where Thomas lives some of the time, following reports that an animal had been injured.

Miss Davis, prosecuting, said: "As they went to the door, they could see blood spots on the steps.

"Miss Stanislaus brought the animal to the door and the police officer could see it was injured and had trouble supporting its own weight. The officer asked if it had been receiving vet treatment, and she said 'no'.

"Mr Thomas said the animal had been in a fight in the park and had sustained the injuries that way."

Cash was taken away by RSPCA officers the next day to be examined by a vet, who found Cash's spine was fractured, he was underweight, there were bruises on the rib cage and back and his left wrist was swollen.

Miss Davis added: "The animal was caused considerable suffering. The vet said it appeared to have been received blows from a blunt or heavy instrument, or had been injured by kicking."

Stanislaus's lawyer said: "She fully accepts she failed to protect the dog adequately. She was previously of good character and does admit she should have acted more quickly to get the proper care for the dog."

Thomas's lawyer added: "This is a case of short to medium-term neglect. I would ask for a community penalty to be given."

Presiding magistrate Mr MacAndrews said: "This can carry a community penalty or up to 12 weeks' custody."

Sentencing has been adjourned until January 8 next year. The dog survived its ordeal and is being cared for by the RSPCA.
