Hot sun, 100kmh speeds and excessive noise.
These were the conditions a young puppy was subjected to over the weekend when it was spotted in an open cage strapped to the roof of a car barrelling down the Bruce Highway towards Gympie, Queensland, The Gympie Times reports.
The RSPCA is now trying to identify the driver of the car, which was seen on Friday and Saturday between Gin Gin and Maryborough and may have driven through Gympie on its way south.
According to one witness who posted online, the puppy looked to be about four months old.
"I imagine (it was) terrified as it was subject to H'Way noise and over 100kph wind without shelter at all... what would this do to a human?" they said.
