Inbreeding Co-efficient

[Pariah]

Hi guys

Just wondering about something I read the other day. I'm not sure how this would work for dogs but while looking at my horse books about breeding from a small gene pool it said something about Inbreeding co-efficients, which is a formula to give an estimate of how much in breeding has occurred already in the lines of any given animal. Do breeders of Wolf dogs do something like this?
I was reading in particular about Friesian Horse societies doing it to preserve lines and to try and stop genetic problems. Just a question thought I would ask seeing how I'm new to wolf dogs and all.

Thanks for you time and responses
