Sadly, there is no real chance of finding the amazing dog that risked its own life to haul an badly injured dog to safety. The event actually happened in March. And unfortunately the injured dog died.
Like many/most countries, Chile isn’t an easy place to be a dog. It’s estimated there are 220,000 stray dogs in the Santingo area alone. Earlier this month, Chilean authorities raided the Benjamin Vinuña Mackenna Animal Protection Society where disease is rampant and animals are being killed in huge numbers instead of sheltered and adopted out. This organization was established in 1915 and reportedly is representative of the conditions in most shleters in Chile.
Here’s an interesting gallery of dogs in Chile.
