The 10 year old crossbreed, who was named "Elmo" by his rescuers was found covered in urine and faeces with multiple dislocated and broken bones. He was taken to a local RSPCA centre but had to be put down.
RSPCA inspectors said it was the worst case of animal cruelty they had ever seen.
- Elmo found with a dislocated hip, shoulder, broken legs and paw fractures
- RSPCA said every bone - all 319 - had previously been broken during life
- Animal had to be put down and RSPCA now trying to trace cruel owners
