The dog, called Tyson, was abandoned in a garden shed for three months and left to fend for himself over the summer.
Tyson also had a severe skin condition from head to tail, open sores on its legs and pus seeping out of its eyes.
The tragic dog was taken to a vet, but he had to be put down because his injuries were so severe.
Tyson’s owner Sandra Sangha, 42, pleaded guilty to causing unnecessary suffering to a dog when she appeared at Birmingham Magistrates’ Court on January 6.
RSPCA inspector Dawn Burrell, who investigated the case, said: ‘When I looked in the shed, Tyson was collapsed in the corner by a hole, where he was exposed to wind and rain.
‘He was in a terrible way and there was no food or water for him. Sadly he had been in this way for at least three months.
‘Tyson’s skin was so crusty and sore from his skin condition that I couldn’t tell what breed he was.
‘On top of that, he was very thin and had horrible sores on his legs and pus coming out of his eyes.
‘He was very clearly neglected and was so weak that I had to carry him from the shed to my van to get him to the vets.
‘There is no doubt about it – he suffered terribly. I still haven’t forgotten the sight of him curled up in the corner of that shed.’
