How old is the oldest miniature pinscher?

I would say... 12 to 15 years. The small dogs usually live longer.

I'd say up to 15 years.

According to the Second Edition of the Encyclopedia of Dog Breeds, Miniature Pinschers generally live from 12 to 14 years. The lifespan of a dog depends on health and size, meaning that a Miniature Pinscher could live more or less than 12 to 14 years.

The reason why small dogs usually live longer is that they do not put as much strain on their joints as bigger dogs. Bigger dogs usually have joint problems.

Dogs live shorter lives than humans due to their higher metabolism rate. Metabolism is the process of breaking down solids and liquids for energy. The higher the metabolism, the shorter the life. Small dogs have a higher metabolism than big dogs, but they live longer because they are smaller. This means they don't have to pump blood as hard as bigger dogs and their lungs are smaller, so they don't need as much oxygen. Life spans really depend on health and size, though.
