Go back to the 1800s - the damsire of Wise Counsellor, Russell (a SW and winner of 19 races), was by Eolus out a mare by Scathelock, these being half-brothers, both out of the mare Fanny Washington. If anything, old-time breeders inbred more closely than we consider acceptable today and that includes to females.

Take a look at George Pope's genetic masterpiece, his homebred Hillary, for an extreme example of inbreeding to superior females.

Am I the only one that doesn't like horses that are over inbred?

Cajun,
I've inbred twice to the third gen. Both hold promise and are physically correct.
I just had to face the fact that T-breds are ALL inbred to a limited gene pool.
The best would be to out cross, but it's very hard to find no Native Dancers, Northern Dancers, Mr Prospectors, and so many others.
You "roll the dice" and hope for the best.

I like it if it ties in a pedigree, is through top quality individuals...

That's why breeders cull! Or at least they used to. Geld the colts who get the bad stuff, so it can't be passed on, sell them for riding horses. Inbred fillies sometimes produce better than they run so some breeders retain them to experiment with, otherwise, like the polo pony I rode at one Bluegrass Farm, should be taken out of the TB gene pool. Nobody put a fortune into any one breeding in those days so a failed experiment wasn't the end of the farm.

Yeah, which is why I don't like it. I don't mind seeing some inbreeding (not in the first 3 generations, though.) A horse like Quiet American, for example, should have never have been bred IMO. Way too fragile for my liking because of all the inbreeding, but hey, without him, Bernardini wouldn't be here.

Balletto,
The ones I mentioned were to get Alydar.
Now if it was inbreeding to Storm Cat...I'd have serious doubts. The front leg defects would only become moreso. JMHO.

Alydar is a great name to see in a pedigree. I adore inbreeding to Crimson Saint through Storm Cat, but not Storm Cat himself... at least yet.
