I have boarded my Horses with a stable one time where the owner was a loooong time Horse guy.
But he had old style thought of how to treat Horses my Horse at the time didn't like men at all I told the owner that because I was going to do the feeding and cleaning of the stall.
But I came in there twice while he was in with my Horse I asked him why he said he was going to turn my Horse around for me he didn't like a horse that got to make the choice of who was in the stall with him.
I took him out that day because I was fortunate enough to have had found another place for him.
But my Horse did take something away from that stable a bigger hate for men.
And since my Horse was a Percheron Clydesdale cross when he got upset you had to watch out.
