The RSPCA has released photos and a video of the flea-ridden Staffordshire bull terrier cross, which was found in a car park by theÂ ramparts in Portsmouth on Wednesday.
The old, tan-colouredÂ dog was rushed to The Stubbington ArkÂ RSPCAÂ Animal Shelter by the member of public who found him but died before arrival.
Fleas, overgrown nails and a small growth were some of the signs of neglect found by vets at the centre.
Understandably the story has provoked an angry reaction from readers, who have urged people to contact the animal charity if they have any information about the dog and its owner.
Here are some of the comments from our Facebook page:
Amanda Jane: '˜They need to be found and sent to prison and never allowed pets again. Disgusting.'
Gemma Denise Foran: '˜It's so unnecessary, if you can't cope just take it to a shelter?!'
Gloria Saundry-Fearnley: '˜I hope that they find this person, and ban them from ever owning a pet again,plus a prison sentence.'
Emma Cannon: '˜This is disgraceful how can any kind of human being do that to a poor defenceless animal.'
Sue Brown: '˜Unbelievable that people are so heartless!'
Louise Bull: '˜It's worrying that we live Amongst people so cruel and heartless. Rip poor little doggy.'
Joyce Robbins: '˜Disgusting behaviour from a human being. Why would you do this? Why not just take the dog to the vets or RSPCA and allow them to care for him and hopefully find him a home he deserves.'Â
Nichola Bryce: '˜How awful and frightening for that poor dog. That's broken my heart.'
Claire Tee: '˜Shocking! Hope the person gets caught and prosecuted!'
Vicky Perry: '˜No need for this... take the dog to the shelter. This is just cruel and they deserve a prison sentence.'
