For example I noticed that Dorotas Wildcat's CLICK HERE dam Droopys Danneel carries individuals in her pedigree that replicates 94% of Black Shiraz or his full brother Big Ginger Boy's pedigree CLICK HERE .

As well as the obvious cross duplications of Ginger, Waverly Supreme and Temlee highlighted in red, if you look at the blood quota table below the pedigree you'll also see Sabby's Image, Monalee Champion and Mandalass also cross duplicated.

This means that the only line remaining in Black Shiraz's pedigree that's not cross duplicated within 5 generations is Shamrock Point's damline Gruelling Point. So of the 16 lines in Black Shiraz's pedigree 15 of them have been cross duplicated - 94% approx.

From a basic pedigree perspective if you had a broodbitch where Black Shiraz or Big Ginger Boy had been previously successful with that bitches damline, an outcross such as Dorotas Wildcat shld probably be on a shortlist of sires to consider for her as his immediate dam Droopys Dunneel carries individuals in her pedigree that reintroduces Black Shiraz back into the line at an extremely high percentage or itensity . There are also other areas such as 'x' path, outcross positioning, front page intensity, sex balancing, xy angles and whatever else you'd like to incorporate into the pedigree to consider as well.

Imo it's just never the one or perhaps in this case even two dogs that are the influence. It's 6 dogs that make up the niche with the example I've used. Cheers and hope it helps.
