Sorry, I have not completed this page yet. But the good news is that I am in the process of writing a scientific article describing the process.
In the meantime, I suggest listening to these podcast episodes where I describe the procedure and results.
Equiosity (episodes 27, 28, 83, 167-169), Horses for Future (episodes 6,7) Friends on Horses, Drinking from the Toilet (episodes 161, 162) and An Equine Conversation (S3 E4).
