Greyhounds Titanium Bolt and Shinboner Star were seriously injured after racing at the Mandurah track last weekend.
On Friday, two-year-old Shinboner Star had a left hind leg tarsal fracture and two days later, three-year-old Titanium Bolt suffered a right hind leg tarsal fracture.
Both greyhounds were transferred from the racecourse to a vet hospital for assessment and treatment and are now listed as retired on Greyhound Racing Victoria's FastTrack portal.
A spokesperson from Racing and Wagering WA said the duo was now entering a recovery process.
"Titanium Bolt and Shinboner Star were accepted into RWWA's Greyhound Injury Full Recovery Scheme, and have since undergone surgery and are now in recovery and rehabilitation," the said.
"Once they have finished their recovery they will be rehomed.
"Whilst only a very small proportion of greyhound starters (0.5 per cent) suffer major injuries, RWWA has two injury schemes in place.
"The Greyhound Injury Rebate Scheme, providing financial support to owners and trainers to assist with veterinary costs, and the Greyhound Injury Full Recovery Scheme, available where the owner and trainer are able to sign ownership of the greyhound over to RWWA's Greyhounds as Pets programs, where all costs are borne by RWWA."
The Coalition for the Protection of Greyhounds were concerned about happens to greyhounds under the rebate scheme.
Coalition for the Protection of Greyhounds WA divisional manager Andrea Pollard asked for more clarity.
"Rebate schemes exist to avoid dogs being put down, but unlike more transparent reporting in other states, RWWA doesn't publish what happens to dogs removed from the track under the scheme," she said.
"The rebate scheme was announced via a two line entry in a RWWA newsletter and there have been no transparent statistics published on how the scheme is working.
"What happens to these dogs once they're removed from the track?"
