There have been mnay half brother half sister matings done in the UK usually with unrelated lines on the other side which this is. Having said that, it is closer than I personally like to do. If this is far back in the pedigree it wouldn't worry me knowing many of the UK/European lines well. Annef

I would worry more about lack of clearances.

Weird I ended up at a totally different dog then the one the threadposter put in. The one I saw originally had no champions in its line.

If you linebreed on a linebred dog the pedigree can become very tight in a hurry. I find COI's and especially the degree of influence of particular dogs in the pedigree to be more informative than worrying about anthropomorphized familial relationships.

Exactly. Carefully done linebreedings can strengthen certain traits, including health issues. Breeders will often do linebreedings to a point, and then do an outcross breeding (usually to another linebreed dog with similar phenotype.)
There is quite a bit more to breeding than simply allowing two intact animals to "hook up".

Hi Guys
Since Im looking for a new puppy also what is a good % for the COI to be at on the high end. Im looking at a breeder that both dogs have a COI around 2%.

Actually no way to accurately answer this. If the two dogs had no close relatives then the get would have a low COI also. However you could have two dogs with that low a COI who share one parent and the get's COI would be extremely high. That is why most look at the COI of the litter rather than the individual parents. It really is much more than just a number.

Pedigree: Am CH Libra's Star Spangled Banner CD JH WC

This dog lived a long time despite its tight breeding

Is it good if the COI is 0% on both mother and father of a puppy?

It's not uncommon to not find alot of champions in an English Champion pedigree. Getting a championship in England is much harder than getting an American championship.
