A VET with practices in the Holme Valley and Oldham has been struck off.
A hearing at the Privy Council into the case of Alan Roderick Tait, of Huddersfield Road, Thongsbridge, heard how he lied about carrying out surgery to a dog which he had not carried out.
Mr Tait was originally struck off in November last year but lodged an appeal at the Privy Council which allowed him to continue practising.
But the Royal College of Veterinary Surgeons (RCVS) has successfully applied for the appeal to be dismissed for "non-prosecution".
Mr Tait did not attend the brief hearing where Miss Joanna Smith, for the RCVS, told the Law Lords Mr Tait had not lodged his case despite correspondence from the RCVS.
Lord Hope of Craighead announced the appeal would be dismissed, which means Mr Tait can no longer practice as a vet.
Miss Smith had described the case as a "very serious" one in which Mr Tait said he had carried out surgery on a dog who died, when he had not.
He had also showed an x-ray of another dog.
He was found guilty of disgraceful conduct by the RCVS professional conduct committee, in London, at the end of a four-day hearing.
It heard details of allegations concerning the vet's treatment.
The committee found proved allegations that he stated he had carried out surgery on an English Bull Terrier bitch, Frances, when he had not done so.
They also found proved the allegation that Mr Tait provided an x-ray of a male dog as evidence that he had taken a radiograph of Frances when talking to the dog's distraught owners, Mr Edward Redman and Alison Turner.
Mr Tait had fabricated the description of the surgery, maintained that deception to the dog's owners, showed the x-ray and even produced a packet of bladder stones.
Chairman Mr Brian Jennings said Mr Tait had not demonstrated "any efforts to tell the whole truth to the committee".
Mr Jennings took the vet to task on the point of the procedure that Mr Tait insisted he had carried out on Frances.
Mr Jennings said: "The committee is satisfied so that it is sure that Mr Tait fabricated the description of the surgery which he told Mr Edward Redman and Alison Turner he carried out on Frances and sought to maintain that deception by the production of an x-ray and a packet of bladder calculi (stones)."
They went on to give the direction that Mr Tait's name be removed from the professional register.
Mr Jennings said "Dishonesty will not be tolerated.
"There is no doubt that he acted with conscious impropriety."
