Worming Schedule

That does seem like a lot of powerful medicines to me... I guess that your Vet was really making sure that the infestation was eliminated... Heres the link to Family Pet Services: http://www.familypetservices.com you can get advice there for this problem... Good health to you and your pet! :)

We tend to rotate wormers and worm every 2 months. This is because we have quite a few horses in fairly small pastures, and that helps prevent worms from becoming a problem. We also usually worm any new horses once a month with a different wormer for the first 3 months and then go to every 2 months on them as well - again this helps keep worms from becoming a bigger problem.

I imagine she had you doing the monthly worming to get your horse cleaned out. I'm sure that's long been taken care of by now and you shouldn't have to worm as frequently. I worm our horses every 3 months. The babies get wormed every 6-8 weeks until they're a year old, then I go to every 3 months with them too. I rotate back and forth between Ivermectin and Strongid. This has proven to be a good worming program for me. A friend of mine worms every 2 months. She has quite a few horses in a smaller area so worms are a bigger problem and that's why she worms more frequently. That's proven to be a good worming program for her.

I worm my horses every 8 - 10 weeks. Never had a problem

I have researched worming quite a bit. I worm in the fall, around Sept. 1st. Then I worm after the first frost (making sure that wormer kills bots), then I worm in the late spring (April), and then in June or July. I rotate the type of wormers I use.

That is overkill. It kind of depends on the enviormment your horse is in. It he is in a small pasture with a lot of horses, you need to worm more frequently. All horses have worms. This is just a fact. The dewormers help keep the levels down so the horse stays healthy. I worm every 10 weeks. More if one looks skinny or wormy.

I deworm mine every 3 months. That is the recommended routine here in South Africa. And yes, always alternate the product that you use because worms can become immune to a specific brand when used regularly.
