A Walpole St Peter man has been banned from keeping horses for three years.
Robert Fisk, 47, of Wendals Close, was found guilty of mistreating three thoroughbred horses during a hearing in Peterborough Magistrates Court on Tuesday.
The RSPCA and World Horse Welfare seized the horses, Roxy, Oscar and Tess, last summer after they were found to be wearing heavy winter rugs in summer.
Roxy was found to have a large lump on a hind leg and was later put down.
Field officer for World Horse Welfare, Jacko Jackson, compared leaving the horses in rugs on a hot day to dogs being left in cars.
He said: “It is the saddest case I have ever dealt with as we have been talking to this man for two years. Myself and the RSPCA have been trying to advise him and he just did not listen. Taking him to court was a last resort.”
The RSPCA was called in July 2014 after concerns were raised about the horses. Fisk was given animal welfare advice but when this went unheeded, a vet advised that the best thing would be for the police to seize the horses and place them into RSPCA care.
RSPCA inspector Dean Astillberry said they were left in a field with a makeshift fence made of metal stakes which could have been perilous for them.
He said: “The horses were clearly overheated in these warm winter coats in the middle of summer, and the vet said this was likely to cause them to suffer. They were very lethargic, breathing heavily and in clear discomfort. They transformed once they got to the rescue centre.
“This was a case when the owner just wouldn’t listen to any advice about how to care for his horses and as a consequence they were put in danger, with their welfare compromised.”
Fisk was found guilty of causing unnecessary suffering to Roxy by failing to provide veterinary care for a painful hind limb mass, failing to provide a suitable environment for all three and failing to provide for the needs of all three by covering them with inappropriate rugs for the weather conditions.
He was disqualified from keeping equines for three years, given a three-year conditional discharge and told to pay £750 costs.
