What Does COI Mean?<\/h1>\n\n\n\n

COI stands for Coefficient Of Inbreeding and is the calculation used to determine the level of inbreeding on an idividual dog or puppy.\u2028The higher the number for COI the closer the dog or puppy was inbred. \u2028A very low COI reflects that that dog or puppy was \u201coutcross\u201d bred, meaning the parents of the dog or puppy had little or no common ancestors. A low COI breeding should really appeal to those individuals leaning towards obtaining a designer breeds (mutts) as basically a COI of less than 10% would be the equivalent of a mutt breeding, but with the beauty, health and characteristics of a purebred and a breeder\u2019s health guarantee and support.<\/p>\n\n\n\n

I get asked all the time how we achieve reds that hold their colour.\u2028In order to achieve dark red colour a breeder has to start with the dark red colour.\u2028You can\u2019t take two light coloured dogs and achieve dark red colour that is going to hold.\u2028You can\u2019t take a light coloured Poodle and breed it to a dark red Poodle and achieve dark red pups that will hold colour \u2028UNLESS it is a linebreeding on dark red ancestor which will usually be a Majestic dog or VERY old Palmares Lines.\u2028Which will mean a COI of 6% or greater on the litter. \u2028Line breeding on a dark red Poodle ancestor will \u201cbring forth\u201d that dark red gene. \u2028Because very few breeders are concentrating on \u201cColour Breeding\u201d, finding \u201creal\u201d dark reds that hold their colour \u2028and have passed all OFA testing, is near impossible in 2010 and will continue to be impossible\u2028Until more breeders stop using fading reds, apricot and creams in their red programs.\u2028Buyers will find that the only \u201creal\u201d dark reds they can find as of 2010 will have a 10-generation COI of 6% and up. \u2028Once red breeders start concentrating on \u201cColour\u201d (assuming OFA\u2019s are completed of course) THEN\u2028we can acheive colour from outcross breedings like breeders are doing with the more common colours.\u2028Red breeders need to concentrate on health testing of course\u2026but also on colour breeding.\u2028Our BEST breedings of producing that rich Dark Irish Setter Reds have been 10-generation COI = 7.18% \u2028My BEST Dark Brown breeding with exceptionally sweet temperaments in 1980\u2019s was a 10-generation COI = 15.27% (now in 2010 it is 1.11% or less)\u2028You can see these reds and browns on our web page as pups as adults that have held their colour \u2028and are exceptionally healthy, completing all OFA health testing and DNA testing available.\u2028COI is a great \u201ctool\u201d to assist breeders, but breeders CAN\u2019T ignore genetics and expect to get results.<\/p>\n\n\n\n

High COI percentages of over 20% increase the probability that genetic defects will be carried from common ancestors on both sides of the pedigree and will match up to cause the actual genetic disease or defect in the animal.<\/p>\n\n\n\n

Many other problems of a high COI also affect dogs, such as Autoimmune disease and inbreeding depression symptoms, which result in reproductive and longevity issues.<\/p>\n\n\n\n

A COI of 12.5% is equivalent to a half brother to half sister mating or a grandparent to grandchild mating. This breeding is the most common practice for breeders wishing to achieve consistency in type or to \u201ccement\u201d certain traits. As a result the litter should be fairly uniform in type & temperament which is the goal for anyone breeding for show. \u2028This breeding is usually referred to as a \u201cline-breeding\u201d and is one of the \u2028BEST breedings to achieve PERFECTION.<\/p>\n\n\n\n

A COI of 25% is equivalent to a parent-child or brother to sister mating. This type of breeding is really not recommended by anyone. It is a very \u201ctight\u201d breeding and is usually referred to as \u201cinbreeding\u201d. A breeder could either get really amazing healthy great looking pups as a result, with pups that will have great genotype (ability to reproduce its self) and great phenotype (the pup will visually appear close to ideal for its breed) for the desired breed type, OR the opposite and look poorly and be very skiddish, hyper, aggressive, unhealthy pups as a result. So this breeding will either produce the best or the worst traits of their parents.<\/p>\n\n\n\n

Ideally, the COI of a litter should not exceed the average COI of the two parents. It is highly recommended to avoid a COI in excess of 20%.<\/p>\n\n\n\n
