Factors Attributing To The Lifespan Of Dogs


Pure breeds also known as inbreds. Most people believe that purebred dogs are better but, believe it or not, purebred dogs actually have a shorter lifespan than mixed breed dogs. 

Why? You may ask. It is solely due to the fact that inbred dogs are at a higher risk of carrying illnesses that are encoded in their genes. These illnesses are often ones that are specific to the particular dog breed.

However, why do mixed breed dogs have a longer lifespan? This is because most mixed breed dogs have a larger genetic diversity than purebred dogs.
