    Just watching PDE and it made me check Oliver's inbreeding coefficient and he has indeed got a lot of Homerbrent in him. Mainly on his maternal side, but a little on the paternal also.
    The average Cavalier has an inbreeding coefficient of 5.2% and Oliver is 4.7% so not too bad I guess.
    Has anyone else checked their dogs coefficient?

    That's a good figure!

    However take the average and the KC determiner with a large grain of salt. I don't even think most breeders would think that the average coefficiant is anything remotely that low for cavaliers. When calculated properly I know many breeders have truly struggled to find matings with dogs where the COi wouldn't have been in the region of 15-20+% for offspring. Many show dogs would be quite high. I am not sure how much info is actually going into the MateSelect programme so far -- will see if I can find out how reliable it would be considered to be at the moment.

    Thanks Karlin
    I am very interested.
    I was shocked to see so many Homerbrents are in his family tree as I must say when I was picking up my beautiful puppy I only glanced at it, was quite relieved he still had a below average COI! Phew!

    Lots of the same name isn't necessarily a bad thing -- lots of breeders would be selecting very carefully. However some of these older lines come from a time when people would have done very close matings at times. Often it is the dogs with different kennel names in their background that turn out to have a very high COI as many cavaliers turn out to be closely related.

    My main question about MatSelect is how many cavaliers are actually in the database to provide an accurate COI. Some of the online pedigree databases for CKCS did COIs too and they generally (on average, for dogs I looked at anyway!) produced higher COIs than the KC stated average.

    My George's COI comes out at 2.2%.

    As you said Karlin, I do think this is a good number but I'm unsure as to whether or not it means a lot if not every dog is in the database.

    Do you not think that the KC will have all dogs in the database enabling them to calculate the COI?
    You have to register a pedigree dog?
    Maybe they only use the 6 generations on his pedigree certificate which is flawed but they must know how every dog on the sheet is related if they were all registered?
