A carload of Pomeranian dogs is among almost 200 emergency calls about animals and children locked cars dealt with by the Automobile Association so far this summer.
AA Roadservice National Manager John Healy is warning parents and pet owners to be more aware of where their car keys are and not accidentally lock them in their cars with their kids or animals.
"February is often a hot month so it is important people remain vigilant and hold on to their car keys to avoid what can be an easy and dangerous mistake.
"The temperature inside a car without any ventilation can rise rapidly, and it doesn't take long before children and pets suffer the effects of heat exhaustion, with its potentially fatal consequences."
The total number of rescues between December 1 and January 30 is up seven on the same period 12 months ago.
