Pedigree Dogs Exposed - avoiding inbreeding for those who can't do the math
Moving forward...
Here's a very simple idea from Professor David Balding of Imperial College London. This is great for anyone struggling to calculate the coefficients of inbreeding.
How not to buy an inbred pup.
Check any prospective dog's pedigree and make sure all of the dog's grandparents are different and that they are not descended from each other, either.
Any duplication - simply walk away.

That was 12 years ago and since then I have become very worried about the state of my dog's breed, especially when I compare him with the working strains of spaniels.
I got the pedigree out again recently and started to make a note of the names that appeared more than once.
It got so difficult I had to put it on the computer using a table with different columns.
This is what I found, and I wonder if this is a record.
It was a five-generation pedigree, which should consist of 62 different dogs.
There were only 29 dogs in all and 11 of those appeared on either side of the pedigree (ie, both the father's and mother's side).
