<I often see the inbreeding co-efficient on GSDs etc (particularly those from abroad) is this restricted to certain breeds or groups as I have never seen it in my breed? >

Hi Tohme, have started a new thread for this as the other one is not for discussion :)

I have not noticed any breeds particuarly that give inbreeding co-efficients/ It is just that because I am so interested in Dobermann genealogy and have the means to do it automatically I can work it out for any Dobermann I have enough ancestors for.  Perhaps the ones you have seen also have someone interested in genealogy?

Hmmmm, they were advertising puppies or studs etc so I don't really know; I was just curious; seen it in GSDs in particular.

I wonder if there are enough GSD's around to get a really low inbreeding co-efficient or if they all go back to the same few dogs within 20 or so generations?

I had mine done on my Golden.  Came back 0.0%

How many generations - it is easy to get 0.0% with three or four generations but I generally work on a minumum of 10 and often 15 or 20 generations

For instance my new pup is
Generations           COI
3                          0%
4                          0%
5                          1.15967%
6                          2.44827%
7                          4.04%
8 (complete)           4.73976%
10  (some missing)   6.73873%
15                        11.2844%

Sorry for asking this but I have been trawling the net for 40 minutes and I can't find the answer to my question.   What is inbreeding co-efficients?

If you type in Coefficient of Inbreeding into Google, you'll come up with masses.   Or try 'inbreeding coefficient'.   I always believed that you had to state how many generations you were dealing with to see the influence of a particular dog on the one you are interested in.

The maths are a bit complex.

One of the dog papers sometimes provides this info. with the Crufts winners pedigrees - it always fascinates me.  I remember that the Yorkie, Ch Ozmillion Mystification had an extremely high coefficent, and all were Ozmillions too!

Ah that's what COI means! The Bullmastiff database nearly always has a COI percentage against each dog and I'd wondered for ages what it meant.

Thanks for that. :)
