Well I tend to like rock the apple cart…
Here goes. We did breed basically that… minus the conformation… lol. My daughter has a lovely appaloose that she showed for years… qualified her for the world shows. The mare receivied her OMB (Outstanding Member of Breed) award at 4. This mare showed in Halter, suitabity for Dressage, showmanship trail, western pleasure, hunter under saddle, reining hunter hack and jumping… Points in all events… plus has gone roping, cattle penning and barrel racing… Any to make my long story even longer… my daughter has always preferred english so after this mare cleaned house every where they went… she started her jumping… then eventing… then right up to Third level Dressage. Everyone who saw her thought she was warmblood. (she is a dapple grey). Obviously she is a true athlete, and a willing partner as they did it from my daughter being 13 and up. With such a horse… (yes, you do want to perpetuate that mind and willingness, and overall ability… I do anyway). We bred her Riverman (hol), and low and behold she had an amazing colt.
The funniest part of this ever so long story… We had three foals that year… two out of Warmblood mares with strong pedigrees, all three by good strong sires…, And when anybody knows that there is a half stock horse out there… he is never the one selected… He is incredible… Did we luck out… Absolutely… but a great mare to a great stallion… is stacking the odds, no matter what the pedigree says.
This particular colt is fancy mover, correctly built and smart with natural curiosity. I absolutely would do it again. But my mare is not Short, Stocky or downhill.
And as far as temperament… When my grand kids are learning… you bet… It will be on a very forgiving quarter horse type… from there… they can move up to a WB x Stock horse… …
