Importance of DNA health testing
Testing can help with planned breedings to minimize risks of illness. It can also alert people to potential health risks that their dog may develop so they can take steps to modify their dog’s lifestyle.
The best use of genetic testing is for predicting and preventing canine health conditions.
Any and all breeders can do these
tests but often choose not to due
to the cost or not believing in DNA
tests.
Please when choosing a puppy
of any breed check that the
parents have been health checked
and tested.

Genetic Coefficient of Inbreeding
COI
Genetic coefficient of inbreeding (COI) is the most accurate method for measuring inbreeding. Unlike pedigree based COI calculations, genetic COI evaluates the actual pieces of DNA in your dog to identify which proportion traces back to inbreeding. Embark’s genetic COI assesses over 230,000 markers and can detect inbreeding in far more past generations, as well as better inform on strategic breeding crosses than typically expected from pedigree based calculations. Genetic based COI results can vary from pedigree-based COI by as much as 70%.
The average COI for purebred dogs is ~20%. Specific breeds can be higher or lower than this value. For some breeds, the average coefficient of inbreeding can approach or even pass 40%. Because these are average numbers, individual COI can vary.
