I've heard and seen people say never ever share brushes for more than one horse. I've also seen people say it doesn't matter. For a long time (typically when I was riding western 6-7 years ago) I had one/each brush for each of my horses-they only shared a hoof pick.
Since I started riding english at a barn (5-6 years ago) I share brushes between horses.
Just wondering what everyone stance on that is, and please explain why. I'm just trying to gain more info! Thanks! :)
