Your horse is an individual, and he should be dewormed that way. Your veterinarian can perform a "fecal egg per gram" (or "fecal egg count") test to help you determine which dewormers are best for your horse and how often you should use them. Once you've got a plan in place, you can rest assured that we've got you covered, from paste dewormer to daily dewormer supplements, all at excellent prices.
