SandClear™ 10lb pail for horses.

Contains psyllium seed husk, a natural fiber that increases ration bulk. Recommended by veterinarians, psyllium absorbs water in the intestines to form a gel-like substance which increases bulk, softens stools and keeps things moving smoothly through the intestinal tract. Highly palatable apple and molasses flavored pellets mix easily with feed. For horses of all ages, including young foals.
