In the summer months, Midgen said, the SPCA sees an increase in complaints relating to animals without shade, lacking fresh water, and dogs left in hot cars.
All of those welfare calls could be avoided by owners putting provisions in place and planning ahead for their furry family members, she said.
Dogs left in cars, she said, was a common welfare issue over summer and she hoped owners were mindful of the new regulation and the risk to their animals.
The interior of a car can heat up very quickly on a sunny day. Leaving the windows slightly open has very little effect. This situation can be extremely dangerous - even fatal - for dogs and is entirely preventable.
A cat or a dog can die from heat stress within 10 to 15 minutes.
"If the purpose of your trip is not for your dog, leave them at home. If you must take your dog with you in the car, bring fresh water and a water dish for them and always take your dog with you when you leave your car."
Midgen has urged anyone that saw a dog suffering in a hot car to immediately find the owner or call the SPCA or police.
She said they must not smash the car window as this could put them and the dog at risk.
