Ooh, Goldie makes me faint!
On her sire's side, you've got Shining Spark, who was one of the base studs in Carol Rose's breeding program. Reining royalty there. Also, Taris Catalyst was a NCHA money winner. Really old powerful reining and cutting lines there.
On her dam's side, you've got even more cutting and cow horse royalty, but it's a little farther back; Doc O'Lena, Peppy San, War Bond Leo, Docs Drifter.
Basically, you're looking at a cowhorse through and through.
As for Dunny, again, you're looking at reining/cutting lines, but the names I know on that one are a little farther back.
Sire's side: Double bred Mr Gun Smoke, who was a NRHA and NRCHA hall of famer, NCHA money earner. Also have Leo San and Doc Bar back there. Again, cutting bred.
Dam's side: You got Laker Doc right there, who goes back to Doc Quixote. Cutting royalty. Lots of Doc Bar in that side. THEN, you look down at the bottom and see High Brow Hickory. He is the sire of High Brow Cat, who is the leading sire of cutting horses seen in the ring today.
Basically, both those babies should eat a cow up and look pretty doing it. If you ever want rid of either, I want to get a chance at them.
