~ COI % and Inbreeding (Wright’s Coefficient of Inbreeding) ~
~ Test Mating COI's done Before we Breed..... ~
_There are no COI's to report for the pairing of any of our Female and Males, as they are too low to record. (This is an Outstanding result.) COI's are very important in breeding, as too much In-Breeding will cause Genetic Health Problems.
Because Goldendoodles have Standard Poodles in their bloodlines, we feel it is important to check the COI's in any dogs we will use in our Breeding Program. We check the COI of any dog we plan to buy against any dog we plan to bred it to before we buy the dog. We keep our COIs under 2%

COI % and Inbreeding (Wright’s Coefficient of Inbreeding)
All pure breeds of domestic animals are inbred. (Keep in mind that to a scientist “inbreeding” means the breeding of related animals, which would include what we breeders call “line breeding.”) But how much is too much? Without it, the breeds could never have been developed and would not breed true to type.
The ideal COI for your dogs is anything under 15%. Above this level of inbreeding, an impact on the quality of the dog is felt heavily and increases exponentially as the inbreeding increases. COIs under 15% have no negative impact on dogs.

Frequently Asked Questions
Does the COI of my dog change as it gets older?
No. Your dog's COI will never change.
What is COI?
Technically, the COI is the probability that both genes of a pair in a dog are identical. Simply put, it's a measurement of inbreeding.
It is calculated by a mathematical formula that is somewhat complicated to many users. The function is...
COI = sum[ (.5 ^ (a + b + 1)) * (1 + c) ]
a = Generations between sire and common ancestor b = Generations between dam and common ancestorc = COI of common ancestor
If a common ancestor does not show up on both the top and bottom sides of a pedigree, it will not impact the COI of the dog. Using this principle, you may breed a highly inbred bitch to a highly inbred dog and end up with hybrid offspring that do not have any inbreeding whatsoever.
