City of Swan rangers have found nothing after responding to reports a a dog was trapped down a drain in Beechboro on Thursday morning.
The City sent machinery to lift the concrete inspection cover, but a camera lowered into the area found nothing, staff confirmed.
Ten-year-old Braden Jackson and his friends made the discovery about 5pm on Wednesday, Nine News Perth reporter Nathan Brooks said from the scene on Thursday morning.
"We walked back down the street and we could hear this yelping sound; it sounded like a duck," the boy told the station.
"We put our ears near it then came up here and banged on the door and said we can hear a dog down the drain."
His father called emergency services who arrived around 7pm and tried without success to get access to the area the dog was thought to be.
It is the second time this year emergency services have searched drains for an apparently nonexistent dog.
