The Rafeiro do Alentejo, a remarkable breed from Portugal, is known for its loyalty and protective instincts. These giant dogs naturally gravitate towards family homes, where they serve as loving companions and vigilant guardians. With a robust physique and a calm demeanor, they embody both strength and gentleness, making them unique among large breeds.

On average, Rafeiro do Alentejos live around 12 years. While this lifespan is typical for giant breeds, there are factors that can influence how long they thrive, including genetics, diet, and overall care. With proper attention, many Rafeiros can enjoy vibrant, active years alongside their families.

Research in geroscience is paving the way for longevity support in dogs, potentially benefiting breeds like the Rafeiro do Alentejo. A new veterinary longevity pill, inspired by studies on compounds like rapamycin and senolytic therapies, could hold promise for enhancing the healthspan of these large, noble companions. While it’s still in the investigational stages, the goal is to empower dogs to lead longer, healthier lives.
