Can't you see it in the picture? :)
Depends on how you count.. we count 3 gaits as normal but I've noticed you tend to say regular horses have four, separating canter and gallop..
Anyway, he can: walk, trot, rack (+foxtrot, stepping pace which I don't encourage even if it's smooth, and some kind of slow and good fourbeat gait possibly flatwalk o the like) canter, gallop and two beat/flying pace. I don't ride the flying pace as it feel unbalanced but he did it before he learnt to canter properly. I've just recently started to ask for trot.
Note; first time I've worked on getting a trot under saddle, excuse my seat in the trot as I'm both not used to trotting and has lost my balance and I want thecues for trot and rack to be as different as possible especially in the start. The walk isn't great either and I have no excuse for my seat in the walk and rack picture..I usually sit correctly.. :3
