An original Rethink invention, this thermal dog collar actually contacts a dog owner's smart phone if their pooch is in trouble.
Made of a SIM card, a thermistor, a few LEDs and a coded chip, the Dog Caller operates like a cellphone without a keypad or screen. When the collar hits 26.5 degrees, the device will alert your phone via text message.
The prototype collar is fully functional and together with the Toronto Humane Society we are working with designers and manufacturers, as well as looking to crowd-fund the final product with the end goal of having it widely available to the public in the New Year.
