I do manners. When I touch the horse all over the body I put middle fingers into the horses mouth where the bit should be and I play and I feel the tongue and corners of the the mouth and he enjoys it. I also try to convey some feel of energy through my fingers. When my hands were salty due to the sweat he likes them more. Is it OK if I put a snaffle bit in his mouth and hold the rings with my fingers to play and learn the feel of the tongue, contact and energy flow, then do this with 10 cm rein and then 20cm etc. ( I do not now what length could be achieved from the ground). Is this procedure for developing feel for rein contact OK? Can I use a drop of salt on my fingers and later on the bit as some sort of motivation?
