If so have you noticed a difference in your mare?
I have a mare who is just nasty on trail rides if there are more then 2 other horses in our group, or if she is passed by horses on organized rides.
She thinks she needs to be the leader no matter what once we add a 4th horse to the mix. I tried relax her but I am having an allergic reaction to it. ( I am the only one who can feed ) the horses so need to find something in pellet or crumb form and figured I would see if anyone on here has used mare magic before.
