First, I'm not saying the basics of European dressage are present in other disciplines, any more than I'm saying the basics of barrel racing are present in European dressage, so all dressage riders & horses need to study barrel racing. It is only the dressage queens who believe that dressage is all controlling, and anyone who does anything in common with dressage is benefiting from dressage.
Someone using stirrups is not dressage. Someone teaching a horse basic balance with a rider is not dressage. Dressage does those things in common with other disciplines, but that common core is not "dressage", because dressage is not the 'good riding' that all other disciplines are perversions of...
And MG, reiners do not do collected gaits. As I thought I made excruciatingly clear, reiners use the word "collection" differently than dressage riders do. Dressage trains to collected gaits, and that FEI definition is NOT what reiners do or desire.
That is part of the reason reiners and dressage riders ride differently. And that is why I specified 'collected GAITS', because a collected gait is different than moving forward with some degree of 'collection'. Definitions are important if one doesn't want confusion.
When I try to teach my mare Mia to canter 'with collection', my goal is very different from a dressage rider who uses those same words. And I do not need the system of dressage, or to spend years training my horse in dressage, to teach her to canter with an acceptable level of collection for our purposes. But I would need her to train in dressage to teach her a collected canter gait. Collected canter, as a gait, has had a definition accepted by the horse world for over 100 years. I want to teach Mia to canter with collection, but I do not want to teach her the collected canter gait:
"4. The following canters are recognized: working canter, collected canter, medium canter
and extended canter.
4.1 Collected Canter. The horse remaining on the bit moves forward with his neck raised
and arched. The collected canter is marked by the lightness of the forehand and the
engagement of the hindquarters: i.e., is characterized by supple, free and mobile shoulders
and very active quarters. The horse’s strides are shorter than at the other canters but he is
lighter and more mobile.
4.2 Working Canter. This is a pace between the collected and the medium canter in which a
horse, not yet trained and ready for collected movements, shows himself properly balanced
and remaining on the bit, goes forward with even, light and cadenced strides and good hock
action. The expression “good hock action” does not mean that collection is a required
quality of the working canter. It only underlines the importance of an impulsion originated
from the activity of the hindquarters.
4.3 Medium Canter. This is a pace between the working and the extended canter. The horse
goes forward with free, balanced and moderately extended strides and an obvious
impulsion from the hindquarters. The rider allows the horse remaining on the bit to carry his
head a little more in front of the vertical than at the collected and working canter and allows
him at the same time to lower his head and neck slightly. The strides should be long and as
even as possible and the whole movement balanced and unconstrained.
4.4 Extended Canter. The horse covers as much ground as possible. Maintaining the same
rhythm he lengthens his strides to the utmost without losing any of his calmness and
lightness as a result of great impulsion from the hindquarters. The rider allows the horse
remaining on the bit without leaning on it to lower and extend his head and neck; the tip of
his nose pointing more or less forward."
I want Mia to move at an extended canter, which is not a strung out canter. I have no desire for her to move at a canter with her head vertical, and I honestly don't want her 'on the bit'. And that is right for my riding, but it is not the collected canter gait.
