I’ve started several of my own and sent others out for 30, 60, or 90 days. I think “it takes as long as it takes” as well, but if you’re paying a full training and board fee and you’re 6 months in with nothing really to show, I would be inclined to pull the horse out of the program. I would certainly wonder what is being done with the horse and why.
I recently sent my 3yo holsteiner out to a horse breaker because he has a bit of a naughty streak and I didn’t want to try starting him with my current travel schedule because of the inherent inconsistency. I consider my boy to be smart, but not necessarily precocious, and I would say that he tends towards the “takes a little longer” side of things in the breaking process.
The trainer that had him took about 30 days to get him doing a (very rough) walk and trot (mostly in a round pen). He was cantering within about 45 days, and the next 45 days were spent basically refining the work.
When he came back to me after 90 days he was very solid with his walk, trot, and canter work. He didn’t go on even the slightest bit of a contact (though I worked on that after he came home…NOT to get him “in a frame” of any sort, simply for him to learn that he could continue to go forward with a very light contact on the reins). He had done some basic lateral work and had done a handful of little jumps and poles at the trainer’s place.
I rode him for another 20 days and then took him to a Greg Best clinic to start him jumping for real. Here he is at 3 1/2 months under saddle:

In my experience, my boy’s progress is pretty average for a horse without any “issues.” With that being said, my plan was to get him broke and jumping over the course of 90-120 days and then turn him back out until next year. That means I do a little bit more with a horse then I would do if my plan was to keep him going through the winter and into the spring. Maybe your trainer’s plan takes this into account???
Either way I would question why the horse wasn’t doing more than walking and trotting after 6 months of training. There may be a very valid reason, but I would expect to have it explained to me in great detail when I spoke to the trainer. I would not be happy paying a full training fee month in and month out with no end in sight UNLESS there was a very good reason.
