Dogs have been present in the Americas for thousands of years, with evidence suggesting that they were among the first animals to be domesticated by indigenous peoples. Early Mexican civilizations, such as the Maya, Aztec, and Zapotec, likely had domesticated dogs that served various purposes, including hunting, guarding, and companionship. Over time, indigenous breeds of dogs emerged in different regions of Mexico, shaped by their local environments, human interactions, and cultural practices. These dogs were often valued for their versatility, intelligence, and adaptability to diverse climates and terrains. In urban areas of Mexico, street dogs, often referred to as “perros callejeros,” are a common sight. These dogs are typically of mixed ancestry and roam freely in neighborhoods, scavenging for food and forming bonds with local residents.
