A dog can withstand a body temperature of 42 degrees for only a short time before suffering irreparable brain damage or even death, he said.
"If you have to leave your dog in the car you should check them every 10 minutes as a minimum to make sure they are okay," Mr Vincent said.
"If you don't have to take the dog with you in the car, then don't."
Animal Management Officers monitor dogs found in cars and will contact police and the SPCA if they are concerned about their welfare.
Mr Vincent said owners need to remember that shade and water are essential in the summer months, and he advises it's best to avoid taking dogs for a walk in the middle of the day when temperatures are highest.
Hot sand or asphalt surfaces can burn paws.
"Exercising your dog is great, first thing in the morning or later in the evening. But not at 2pm in the afternoon when it's really hot."
Signs of heat stroke in dogs include panting, red eye membranes, red mouth and looking dazed. Overheated dogs should be gradually cooled down, not put into cold water.
Tips for keeping your dog safe
1. Animals can quickly die in overheated vehicles.
2. Constant vehicle air circulation is essential for pets as temperatures soar.
3. Being able to cool down on wet towels will usually bring a lick of thanks from your pet.
4. Slow, progressive cooling is best for overheated dogs. Dunking dogs in cold water is not.
5. Avoid walking dogs on hot asphalt surfaces or beach dunes and wait for cooler temperatures later in the day.
