But despite assistance from fire fighters and a search of the drain by RSPCA inspectors on Thursday, there was no sign of it.
The Jindowie Residents Group Facebook page first reported hearing a canine at the Ravensbourne Street end of Kalbarri Park on Tuesday.
“Anyone lost a dog? There’s a small sounding dog trapped in the drain at the bottom of Kalbarri Park, Ravensbourne Street end,” the first post said.
“Rangers here and men down the drain but if you lost your dog we need you here to call it.”
A post the next day said a dog could still be heard barking.
The City of Wanneroo confirmed a ranger also heard a dog.
On Thursday, local plumber Hugh Bartlett offered his services with a pipe camera to search the drain.
But again, nothing was found.
Residents attended the scene that night and could not hear any barking.
“Hopefully that means it got out,” the residents group Facebook page posted on Friday.
The City of Wanneroo locked the drain to prevent community members from holding their own search, which could endanger them.
“Monitoring will continue and if an animal is located all appropriate actions will be taken to rescue the animal,” a City spokeswoman said.
“It is normal process for the City rangers, as trained animal welfare officers, to manage such matters.”
The Department of Fire and Emergency Services helped the City by ensuring there was not a dangerous level of gas in the drain before it was searched.
The City and RSPCA urged anyone who heard barking in the drain to report it to the authorities and not attempt their own recovery.
While the RSPCA abandoned the search on Thursday, a spokeswoman said the organisation took the report seriously.
“Despite the complexity within the drainage infrastructure, its depth, length and confined size, the RSPCA WA reassures people that its main priority is to recover the entrapped animal,” she said.
