Over the summer months Ontario Provincial Police get a number of calls about pets left in unattended vehicles. During warm weather you must take precautions against the danger of heat exhaustion and heatstroke for your pets. The temperature in a parked car, even in the shade with the windows partly open, can rapidly reach a level that will seriously harm or even kill your pet. Dogs (and cats) cool themselves by panting and by releasing heat through their paws. On summer days the air and upholstery in your vehicle can heat up to high temperatures that make it impossible for pets to cool themselves. Your dog will be more comfortable if left at home.
