Hay alternatives?

You can soak the hay you already have.

Won't increase the nutritional value of it but it will reduce the dust. Just pull some off the round bale and soak it, no more work than soaking cubes or pellets for him.

Thank you for all of your suggestions, I will be checking into whats local, and available, even if it costs a little extra.

Blue Seal has an excellent product called hay Stretcher. I have several friends who use it and are very satisfied with it.
