Agreed. I’ve not been in Germany long, just over a year, but ride at a facility with numerous M level riders and a few FEI riders/horses. The most I’ve seen are German reins on for riders when they are learning and cannot hold contact with the horse yet. I have seen none of these other gadgets or tools in the tack rooms here or on horses here.
I have been to a few stables here for lessons and to find a trainer/facility. I’ve been to friends farms, so not like I’m an expert or anything but I’ve not seen abusive riding, lunging or handling. I see a lot of good riding and some that isn’t great but also isn’t abusive.
I would be shocked and appalled if I saw something even closely relating to what I’ve seen in the videos. I think most if not all of my fellow riders and horse owners would be as well. I also think that most wouldn’t tolerate it, they would say something. I obviously can’t speak for all of Germany but just my time here in my small area.
