Average lifespan of deceased ancestors (parents, grandparents, great-grandparents) compared with the population median.

• Only ancestors with a precise death date count; living ancestors are not included, so young animals often have no value.
• Above the population median suggests a long-lived line, below it a shorter life — but it is a small sample.
• Lifespan is driven by care and by the age at which the animal entered the registry; it is not only genetics.
