How often does an adult horse have to be wormed?
For a normal horse, an adult equine should be wormed about every 6-8 weeks. (about 5-6 times/year) When your horse is pot-bellied, dull faced, or just not itself, you need to deworm them even if its not time.
Horse are commonly wormed with a commercial preparation available from your tack store. There are various brand names, Ivermectin is the one we use. The wormer comes in a tube with adjustable doses graduated for the weight of the horse to be wormed. Improvement: You never WORM a horse yo DE-WORM it.
For most horses in most circumstances, once every 3 months is sufficient. However, if your horse lives in a small place with limited turnout, he is exposed to more of his own feces, which could carry worms in it, or if your horse is very young or very old and less able to fight worms, then he may need to be wormed as often as once a month. Talk to your vet to find out…
