The RSPCA claims that fewer dogs will be left in hot cars if pet owners can travel with their pets on public transport.

"The RSPCA Queensland receives over 1000 distress calls each year about animals being left in hot cars," RSPCA Queensland spokesperson Alex Hyndman Hill said.

"If owners had alternative methods of transporting their pets, such as being able to take them on the bus or ferry, we would hope to see a reduction in this number.

"From an economic perspective, allowing pets on public transport would encourage people to take their furry friends out and about more often, which brings more business to the local community."

Currently there are more than 107,0000 dogs registered with the Brisbane Council, and 39,000 cats and dogs finding news homes each year.

However, it was noted by the RSPCA that it is very difficult to get around Brisbane with a pet without private transport.
