I am wondering what you would do? My pens are really dusty. It is like talc powder, it poofs when ever a step is taken and it coats everything with a fine layer of dust. I sprinkle the pens daily once or twice to try and control some of the dust. It helps a little , but not enough. My vet suggested sand. I am not really comfortable with sand, but something needs to be done because the amount of dust these horses are breathing in is not heathy either. My vet has 6 in sand in her pens and uses sand clear monthly and feels it will be safe.
