Latest figures show there were more than 2,000 complaints of animal cruelty made to the RSPCA in Northamptonshire during 2014.
Annual figures from the charity have revealed 2,007 cruelty complaints were made in the county last year – 115 more than the 1,892 complaints in the county in 2013.
John Grant, RSPCA superintendent for the South West which includes Northamptonshire, said: “It is extremely concerning that we are still receiving so many complaints about animals being deliberately caused to suffer.
“Most of the complaints we receive involve animals being neglected or not receiving the right care and often we can put that right by offering welfare advice.
“However, it is shocking that in 2014 people are still being deliberately cruel in what can be disturbingly inventive ways.”
One case last year saw a 41-year-old woman from Rushden allow her dog to deteriorate to such an extent that his limbs rotted away.
George had been with his owner since he was a puppy but she didn’t seek veterinary treatment when it was needed.
RSPCA inspector Polly Underwood found the crossbreed with extensive infected wounds on all four limbs.
He had a large tumour on the pad of his right foot and all four of his limbs were covered with bloody and infected lesions from his paws to his shoulder.
It was apparent from the smell and sight that George had been like this for a long time.
George was obsessively licking and gnawing his legs and in some areas it appeared the skin had worn down to the bone. The dog struggled to walk and blood oozed when he did so.
Inspector Underwood had to carry the dog to her van in a duvet and once at the veterinary surgery George was carried in on a stretcher and examined by the veterinary surgeon.
But he was howling so much due to his pain and distress that George had to be put down on welfare grounds.
In passing sentence the owner was told: “In the 22 years’ experience of this bench this is the worst case of animal cruelty any of us have ever seen.
“We note the vet said also in her 15 years’ experience it was the worst case of animal neglect that she had seen.”
