I came across this little blog post today and found in pretty interesting, http://blogs.dogtime.com/border-wars-a- ... nding-doom. Granted, this is about Border Collies, but it is applicable to all pure bred dogs. Here is the important part of what he has to say:

"The chart shows the Coefficient of Inbreeding of the entire ISDS Border Collie Gene pool through the years. The solid line looks at only the last 6 generations and assumes that all the dogs in that last generation are in no way related. The Dotted line looks at all generations back to the beginning, also assuming that the original stock is in no way inbred.

The two lines trace each other in the beginning because there simply weren't 6 full generations of data. But the split you see right around 1960 shows that despite the overall trend of breeders to outcross, resulting in the 6 generation line dropping from a high of 4% in the early 1960s down to about 2% in 2000, the real trend within the breed is a skyrocketing line approaching 8%."

Now think about what this means for Lacys if we've only been following three generation pedigrees. With such limited stock, there is no doubt Lacys are inbreed, yet it is all done haphazardly because people are only ever looking back three generations. This blind breeding is the truly scary part.

Thats a nice little graph, illustrating what I have been trying to explain for years :)

This is another really interesting article, from one of the top canine geneticists in the country, studying the effects in inbreeding, line breeding and out crossing on a single pedigree: http://www.vin.com/proceedings/Proceedi ... &O=Generic.

One of his most interesting statements? "In this pedigree, the most influential ancestor doesn't even appear in a five-generation pedigree." Definitely food for thought!

Great article!
You know some of these are lengthy reads but they are absolutely worth it ;)
