If a dog gets its head trapped in something such as a cistern, vessel, pot, etc, don’t panic; don’t call the firefighters like you’d most likely do. Firefighters have better things to do than tend to ‘save my pet’ calls. Plus, any delay might end up in the dog’s death. What you should do is to first gather a few others for help. The next step – the quickest way – is to take a hint from these Indian villagers.
