Urge major supermarkets to display warning flyers/signs against shoppers leaving dogs in cars!!!

.....People leaving their pets in cars while they shop is getting out of hand! I think it would be a great prevention method if shops and stores displayed warning flyers/posters in the car park area warning shoppers of the dangers. Anything is worth a shot!  Any animal lover is aware of these dangers but a lot of people still need 'educated'. To be honest, no animal owner should need a deterent against leaving their dogs in cars yet it's still happening so back to basics and lets try re-educate these people. We shouldnt have to stoop to having flyers like this, it's just common sense to anyone, i personally wouldnt even leave a bar of chocolate in a hot car so why would people think to leave a living creature?!   Please sign this important petition, thank you
