If you want REAL dressage movement, look for the following names up close in a pedigree - I tried to pair them based on “common” sires/genealogy :
AP Indy / Golden Missile / Dance With Ravens
Unbridled’s Song / Fappiano / Rubiano / Quiet American
Personal Ensign / Personal Flag / Grecian Banner ** very sound line
Private Account / Say Florida Sandy
Storm Cat / Stormy Atlantic / Giant’s Causeway / Stonesider / Freud
Gilded Time / Timeless Moment
Malibu Moon / Black Minnaloushe (SC)
Star Gallant / My Gallant
Rock Talk / Talc (and any sons/daughters)
Sadler’s Wells / El Prado / Galileo
Distinctive Pro
Lear Fan
What A Pleasure
Nijinsky
This list is by no means comprehensive, but off the top of my head, just stallions/mares that I have seen contribute more than once to absolutely better than average TB movement. When I am thinking good moving, I am thinking like this horse’s movement or better: click
In the engine room, it seems to me, these horses usually have several things in common: lots of heavy dosing of Bold Ruler, Nasrullah, Relic, Owen Tudor, Blue Larkspur, and Teddy. Roi Herod and Hail To Reason also consistently seem, to me, to have good moving kids/grandkids around but those are far back in most pedigrees now.
Generally, some of the recent super sires like AP Indy and Giant’s Causeway have been of particular interest to me, having several sons standing that seem to consistently pass on good movement. Stonesider, a Giant’s Causeway son, had several kids local to me and they just blew me away with their movement - even stiff and sore – I am excited to see them out and about this year in the show ring.
As far as bloodlines to avoid… off of the top of my head, the only lines I will not consider are In Excess and his son Indian Charlie. I have not seen a sound horse in a second career from them yet. The rest I take on a case-by-case basis.
Across the board, no two of my TBs have had the same maladies post track - but generally, just get a PPE - rads of pasterns, hocks, and if you have the money, their back and SI area. Not uncommon for TBs to have very sore backs and sometimes it’s work induced, sometimes it’s trauma, sometimes it’s KS. It’s just good to know what you are dealing with.
As far as type, look for something that is built uphill - not just from the withers, but the neck - the elbow to stifles - in movement, they should be moving up hill with good articulation of their hind legs - they should have a swinging, open walk, and active step. I judge the walk the most heavily - I want a fluid, capable stride - if they don’t have a great walk, chances are they won’t have a great canter. Conformation wise, it can be hard beyond that, as I have seen some pretty funny looking TBs be very nice movers - I prefer to see how their bodies move and work before I make an assessment on their conformation.
One thing I do not do is straight behind with a steep/goose croup. I will accept either or, but not both at the same time.
Make sure to go with someone who is experienced picking out horses at the track. It is normal for them to move completely different after a few days of let down - I have one now that was an okay mover during his jog at the track, but an absolutely gorgeous mover now - several months off track and good, consistent work will do so much to change the way a horse uses his body.
