I'm finally back home... with bad news for my own horse, but I try not to think about it.

At the moment I do some really basic mindfullness exercises with my eldest horse, like grooming him mindfully, being aware of how he feels, or his movements. I tend to get lost in the moment when I choose one part of him, let's say one foreleg and try to get that really clean. I can spend minutes just brushing him, removing the tiniest bits of mud that may still be in his coat...
Sometimes also lay against him and just take in his smell, his body heat and so on...

For those who have already done mindfullness with horses, what did you do?

and with ill-mannered horses I meant horses who push humans, step on our toes, try to bite and so on. I can handle that type of horses, but I always worry about the owner's opinion if I have to reprimand their horse.
