Stewards have adjourned a racing inquiry to determine whether a trainer will be charged after a greyhound that won a Mandurah race tested positive for amphetamine in April.
Former Ravenswood resident Robert Westworth was suspended after drugs were detected in a sample taken from Miss Bondi at Mandurah on April 23.
The greyhound won Race 10.
Racing and Wagering Western Australia's (RWWA) stewards commenced the inquiry on October 28 after ChemCentre laboratory and an independent provider confirmed there was amphetamine in the animal's blood.
A RWWA spokeswoman said "extensive evidence" was presented to the inquiry by the analysts and investigators.
Veterinarian Derek Major was called on behalf of Mr Westworth to give evidence in relation to the analytical data supplied by both laboratories and his opinions as to the likely sources of such levels as reported.
The spokeswoman said the matter was adjourned in order for evidence to be considered and to determine whether any charges were to be issued.
The Southern River resident's seven greyhounds have been suspended pending the inquiry outcome.
The dog is owned by Mr Westworth's partner Michelle Romer, Simon Allan and Grant Adamson.
Earlier this year, Mr Westworth told the Mandurah Mail he was innocent.
"I am innocent and didn't do it," he said.
"I don't know what's happened.
"I have been involved in greyhounds for 35 years. I have a perfect record."
Mr Westworth said he was "absolutely beside himself".
"This has been my livelihood for 25 years," he said.
"For the last three weeks I've had no income.
"I've had my life taken away from me."
Mr Westworth's licence will remain suspended pending the inquiry outcome.
