First off, when breeders think "soundness," they are usually thinking of outcrossing for "hybrid vigor." Inbreeding, unfairly perhaps, has been associated more with "weakness" than strength. Much inbreeding also happens naturally when a prepotent sire line creates generations of the line, as has happened with Northern Dancer and Mr.Prospector, to name two. Conversely, in our racing enviornment, "sound" and "durable" horses rarely create dynasties; therefore, natural inbreeding to them rarely occurs. Another point: In this age of large books and favored commercial lines, "sound" and "durable" type sires, such as Mr. Leader and Naskra from eras past, to name two, are hard to find.

Where do you stand on the theory that inbreeding of 4x4 or closer makes horses unsound? -Jameel Hi Sid,

I’m pretty impressed with Mission Impazible, and I might even make him my Derby horse!

Where do you stand on the theory that inbreeding of 4×4 or closer makes horses unsound?
