OFA, DNA, & Coefficient of Inbreeding (COI) Testing
OFA (Orthopedic Foundation for Animals) was founded in 1966, with the sole mission of promoting health and welfare of companion animals through a reduction in the incidence of genetic disease.
OFA tests, such as hip and elbow certifications, use x rays to check the health of a dogs hips and elbows. These readings can range from poor to excellent, and a certificate is issued to the dog owner after the x ray and examination of the x ray is done by a veterinarian.
These tests are used to check for the possibility of hip dysplasia, and are usually performed on dogs that have the potential to develop this disease.
ALL reputable breeders should perform these tests on their breeding dogs, and should show the certificate to those who want to adopt their pups. While there is roughly a 13% chance that a Labrador will develop hip dysplasia in its lifetime, ruling it out all together is better, in my opinion.
DNA testing should be a staple in ALL reputable breeders regimen. These DNA tests help rule out any genetic traits being passed to puppies from the parents. Myopathy EIC, and PRA are all diseases that can effect certain dog breeds, such as Labrador Retrievers.
The breeder should be able to show those who wish to adopt one of their pups these DNA results. I give a copy of both parents DNA reports, as well as a DNA report of a puppy from each litter.
COEFFICIENT OF INBREEDING (COI)
COI is a means of testing a dogs DNA to check how diverse it's gene pool is. The lower the percent, the more diverse the dogs gene pool is. This gives the dog the potential for ultra high intelligence, and lessons the chances of genetic issues. COI below 10% are exceptional. All of my puppies have a COI of between 10% and 0%- the lowest possible. This number, however, is enhanced by a DNA profile which is clear of all genetic issues. All of my dogs are 100% clear of ALL genetic conditions. When a dog has a clean DNA profile, as well as a 0% to 10% COI, you are getting a genetically perfect animal.
