There is no clear line drawn for what is inbreeding, and what is linebreeding. They're really the same subject with different dilutions and no real definitions by anyone. The "recommended" line not to cross is 15%. Some of the "best" show dogs ever had a VERY high COI.
To produce consistency, the higher the COI, the better. High COI doesn't necessarily mean a higher percentage of health problems. I don't think that any number stated of COI means much at all. It depends on what's back there in the line. We know of some dogs, and we won't talk about this publicly, that we only want on a pedigree once-puts the COI of known problems at 0%.
COI can work both ways. You can lock problems in, but you can also lock problems out.
The problem with most breeders is that they try a little of this, and a little of that, and then you don't know where problems come from.
The most important thing is to know as much as possible about as many of the dogs, and what they have produced, on the pedigree, as far back as possible.
