Well not really but...I've invented a product called KoolDog...if you have to leave your dogs in a car or van (I'm not advocating you do) then you simply put KoolDog in the same area and switch it on. If the temperature reaches certain high or low levels then KoolDog will text up to three people and also telephone the user with a message to say "KoolDog says get back to the car" The mic is also left open for a minute so you can listen, (hopefully not for signs of distress). It's about the size of a pack of cards, rechargeable and all you need is a cheap sim card. (If you put a pic of your dog with the number then you see your dog when the device calls you..don't answer and you've no call charge)

Interested in your thoughts folks...
