Although some Bulldogs can mate naturally, the majority of breedings are done by artificial insemination. This is sometimes because their shape precludes a natural mating; sometimes because the effort/stress can result in a heart attack.

The KC's 2014 health survey found that almost one in five Bulldogs die from heart failure. Although some Bulldogs do make it to old age, they are dead, on average, by the age of 6 - much the same as it's always been, despite better nutrition/vet care.

Interesting to see the changes in the breed since he 1950s. The dogs in this archive mostly have terrible fronts... but are longer-legged and kept leaner than today's show dog.
