In the following charts 'n' represents the number of dogs used in the given calculations.
- For the general population (n=801), the average lifespan is 8.5 years.
- Females are living on average, 8.7 months longer than males (n=796)
- ROM recipients (n=306) are averaging 8.8 years. See chart below.
COI
The Coefficient of Inbreeding (COI) is a calculation of how related an individual's parents are, or a measure of how inbred they are. It reflects the likelihood of any individual allele being homozygous and relative risk of inheriting recessive genetic conditions. I found these scatter graphs interesting in that they really show no pattern and do not indicate a shorter life span with higher COI numbers. The average COI for the breed is 12.7 (n=763)

Causes of Death
The overall cause of death and death under 7 years of age are both clearly due to cancer.

The incidence of different cancers through time.

Longevity by decade of birth, a concerning trend
n= 785
ROM Recipients are averaging 8.8 years
n= 306
My next plan is to analyze longevity by generation. The following is an example using the pedigree of one of my dogs. It compares the longevity of offspring, 3 generations of ancestors, and a calculation that takes into account the genetic influence of each ancestor.
