Por qué los perros grandes envejecen más rápido que los pequeños: un estudio encontró cambios en el ADN que podrían explicar su vida más corta

A scientific study has identified specific DNA changes that may explain why large dog breeds age faster and have shorter lifespans compared to smaller breeds.

Despite sharing similar environments, diets, and veterinary care—such as in the case of a chihuahua and a great danés living in the same household—time affects dogs of different sizes at vastly different rates, with small breeds capable of living up to two decades.
