Bullmastiff Longevity data
I do not yet have enough data collected to deem the analysis statistically significant, but I would like to share the charts I intend to use.
In the following charts 'n' represents the number of dogs used in the given calculations.
- For the general population (n=562), the average lifespan is 8.4 years.
- Females are living on average, 7.6 months longer than males (n=562)
- ROM recipients (n=266) are averaging 8.7 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 12.5

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