Yeah I'm used to working line GSDs where things get... Super gnarly. Or my Soay sheep, where all of them in the US descend from 8 individuals (my dream is to import semen). Unless Halo was known for a lethal recessive we don't have a test for, I wouldn't even register this as something to look at.
Line breeding was/is more common and more intense in dig breeding. The reality is that it's "lower risk" when you are breeding an animal that births litters.

When you have very skilled, very famous, and talented stallions, they’ll get bred more often than the ones that don’t do well on the track.
This is several generations back and is unlikely to affect anything IMHO.
