Folks with a horse has gaited breeding but prefers to trot over walk might find my experience interesting.
First of all, that video looks and describes exactly what my grade mixed mutt of a TWH does. Nice dog walk then trot! Slow down, start again, nice dog walk (especially pointed towards home on the road) then faster and the trot pops out. I know folks run across this same situation with their horses all of the time, even the well bred ones.
I got my guy as a yearling and by the time he was two, he still showed no signs of gaiting. In fact he had such other great qualities that by the time he was 4 I started using him for LD in endurance and we were placing around 20th place out of 50+ riders in his first season. He had the most beautiful loose-rein 9 mph trot that he could hold for hours. Plus he had that competitive edge that made him good at his job (the look in his eye that made me stick him in my trailer and bring him home as a yearling).
At year 4, I gave up on his gaiting obviously - even tho I'd bought every gaiting book that could be read, joined every forum on gaited horses and sent video to trainers - so I became a bit burned out. Plus I own other gaited horses if I needed to get my 'gait' on.
Then along came dressage (cross-training with endurance to stay in shape and work all the muscle groups) and after doing that awhile (he was maybe 7 at the time) he began to offer up the piaffe on his own when asked for a series of half-halts. What the heck? Of course we were not developed enough to hold this for more than 30 seconds (and didn't try to), but it was enough to impress the instructors and brag about and it showed us he had a natural tendency to carry his body and do quite well. But endurance is my passion and dressage runs a close second so we never tried to go farther.
The point of all of this is, suddenly out pops a dogwalk gait at year 9! Yes, it seems it took forever. But now I am getting what the lady in the video is getting! He got a year off while I was pregnant and being a mommy for awhile and suddenly I decide to get on and just go for a slow walk. Suddenly he sees a buddy horse down the road and offers up a 6 mph dogwalk (I had my GPS on). WOW!
So now I've done nothing but walk walk walk for an entire YEAR- and granted it's walk then trot then slow and start the walk again over and over, i can see a difference (maybe not day after day) but week after week, bit by bit (kind of like learning a new language).
Who knows where-why-how this happened - muscle changing, more training, less training - I could contemplate all day but we will keep working the walk and see where we get to! Probably not anywhere very fast at this point...but I never turn down a good project. LOL!
Here is a picture of the mutt in question, just for fun - especially when we are talking about mixed TWH - it's fun to share!
Sorry for the long post but I hope it helps somebody! koty.jpg
