A thread on another forum about Mr. Prospector horses got me thinking about this topic. Of my four horses, three had none of the influences/crosses listed in the title above, and the fourth has one instance of Native Dancer five generations back.
Because I have succumbed to that normal tendency to think that my horses are extra special, I have followed with interest all the literature about the benefits of outcrosses to the stallions listed above. I also rue the fact that it seems really hard these days to find any horse without those stallions in their pedigrees.
Do any of you look for horses which do not have Mr. P, Native Dancer or Seattle Slew, or do you base your racing and breeding choices on other factors? Do you think it is important to maintain outcrosses free of those lines?
Of course I am expecting all comments to reflect how superior my mares are.
Edit to add: a list of stallions is on post #28
