The Rotorua SPCA has been called out several times to dogs left in hot cars this summer, however, the number of cases has not increased, prompting hopes the animal charity's safety messages are getting through.
Manager Sue Kinsella told the Rotorua Daily Post the number of cases was "no more, and no less than previous years".
She said she had anticipated extra callouts during this week's heatwave, but that didn't eventuate.
"Hopefully the message is getting through that pets cannot be left in cars in summer even for just a few minutes."
