An animal charity is offering a £1,000 reward for information after a badly-neglected dog was dumped outside a Wakefield shelter and left to die.
The one-year-old dog, which staff named Jack, was dumped outside Whitehall Kennels in East Ardsley in September and died hours after he was found.
He was emaciated, covered with sores and his nails were so long they were growing back into his paws, PETA said.
The charity is offering the reward for information leading to a conviction.
PETA (People for the Ethical Treatment of Animals) spokesman Suzanne Barnard said: "It is imperative that, faced with a case of such horrific animal neglect and abuse, the community take measures to find the culprit or culprits and prevent such a thing from recurring.
"Animal neglect is a crime, and it cannot go unpunished."
A reward is also being offered for information leading to the arrest and conviction of those responsible for maiming a cat in Wakefield in November.
Jessie was shot three times in the face and then hanged.
The cat survived but was left partially blind and deaf with wounds to her face, lacerations on her neck and burns on her tongue.
Anyone with information is encouraged to contact Crimestoppers.
