Pucón was my introduction to South America, the first place I actually stopped being in transit and started being in a foreign country. One of the first things I noticed was the dogs. Stray dogs everywhere. Stray dogs here are generally hungry, frightened, snarling things. The stray dogs there were happy, amiable, fat and lazy things. They'd trot up, tail wagging to say hello, take any food on offer, and amble off. They played with each other and roamed around in great gallumphing packs of rolly-polly dog.
Despite this, many households kept dogs as pets. These dogs were normally in small yards behind high fences, and spent a lot of time barking their envy at all the stray dogs running around free and easy, or pretending they couldn't see them.
This stayed true of everywhere I visited. South America is Happy Dog Country.
