A Canadian advertising firm is creating a high-tech dog collar for people who leave their canine friends in a parked motor vehicle.
The “Dog Caller” contains a SIM card, thermistor, some LEDs and a coded chip. When the temperature around the collar reaches 26 degrees Celsius (78.8 degrees Fahrenheit) an alert is sent to an owner's mobile phone warning them their dog's temperature is reaching an unsafe level.
