“Watch us come back with a dog,” I joked to my partner as we packed our things for four months on Mexico’s Pacific coast. As it turned out, it was less of a joke than I thought. When you think of Mexico, street dogs probably aren’t the first thing that comes to mind. But outside of the resorts and villas that most tourists associate with Mexico, things are different. The country has the largest number of Mexican street dogs in Latin America. The National Institute of Statistics and Geography estimates that about 70 percent of the 18 million dogs in Mexico live on the street, born as strays or simply abandoned. It’s a statistic that becomes overwhelmingly evident as you walk around.
