Quest is a great wormer to use if you have had your horse on a consistent worming program but the results aren't what you wanted. Worm with Quest and you will see a huge difference in your horse. I had a two year old I wormed with everything out there and he still looked "wormy" with a dull coat and no weight gain. I wormed him with Quest and in 30 days he looked like a different animal. Great product. Do not worm horses with a heavy worm load as this is an effective product and may kill enough worms to cause colic. On regularly wormed horses it works wonders.
