I think there is a lot of truth behind your theory and it honestly sounds like a fantastic idea. I know that when I train horses I have to be 100% focused and attuned to my energy, gestures, the volume and tone of my voice etc… All prey animals react to all of this especially your energy and of course as an ADHDer my energy is naturally too intense for most horses and if I hadn’t learned to curb this I honestly probably would have had a very serious accident by now. For some reason growing up and not knowing I had Tourette syndrome nor ADHD no matter how many adults told me to hold in my tics and my energy I simply could not. No matter how much I tried and how many different techniques were shown to me etc… Horses however were able to teach me this. While I found that this skill never carried over into any other aspect of my life the fact that I could acheive this while riding horses was invaluable. It was so amazing to be able to feel true peace and relaxation even though it was only while galloping through the trails on a 1200 lb animal lol
I think you are on the right track and commend you for opening your mind and looking into this. The other added bonus with this is that taking care of animals automatically (without you realizing it) forces you to adhere to a routine and instills discipline even when nothing else works
