Inbreeding in dogs has real consequences. Research in the Boyko Lab has shown that a 10% increase in inbreeding can lead to a 6% reduction in adult size (poor growth) and
a six- to ten-month reduction in lifespan
. Reduced litter size and fertility are also likely.
Do inbred dogs have health problems?

Do inbred puppies have health problems?

puts dogs at risk of birth defects and genetically inherited health problems
.
What diseases can dogs get from inbreeding?
For ten other inherited conditions, the purebred dog population had greater prevalence than that seen in mixed-breeds: aortic stenosis, atopy/allergic dermatitis, gastric dilatation volvulus (GDV),

Do inbred dogs live longer?

The highest level of inbreeding by far (> 80%) is for
the Norwegian Lundehund
. This breed suffers from extremely low fertility and high puppy mortality as well as an often lethal gastrointestinal disorder.
Why is inbred bad?
Inbreeding results
in homozygosity
, which can increase the chances of offspring being affected by deleterious or recessive traits. This usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.

siblings
. Anecdotal evidence suggests that behavioral issues may arise during key development periods because the two puppies’ deep bond impedes their individual ability to absorb and grasp the nuances of human and canine communication.
How can inbred dogs help humans?
In addition to
helping us find genes that may cause human diseases
, dogs can serve as “model organisms,” helping explain how specific genes cause disease, as well as developing effective treatments for us and them.
