Worming disaster-what did I do wrong?What do I do now?
I'm a new horse mom and I have a 8 1/2 month old baby Friesian. I've had her since she was almost 5 months old. I've wormed her every month with Ivermectin. I read that I should stick with the same wormer for a while, and this I was told that Ivermectin is a good broad wormer. If there were any sings that she had worms, I missed them. She is looking great, in fact she is a bit overweight. This month I decided to change the wormer to Pyrantel. For two days she eliminated an enormous amount of roundworms. They were huge and I can't even put it in words how many she had. I'm horrified. I could see something like this coming out of a neglected horse, not out of my baby. Do I need to do a fecal every month? I did look at her poop before and she had one little worm in her stool once, when she was 5 months old, it was dead and I didn't think it was something to worry about. I'm so lucky that she didn't colic. I feel like I failed her. My sister-in law is an experienced horse person, and she didn't see anything wrong with her. She was also seen by two vets, on three occasions(for general check up and shots) and besides telling me to take her off the pasture, the vet didn't see anything wrong with her either.
And what should I do now to get rid of worms that may be on the ground? I do pick up poop several times a day, but I can't remove 100% of fecal material.
Should I give her another dose of wormer in 10 days? What kind? I'm totally freaking out.
What else am I screwing up?
Thanks in advance for your help!:cry:

When I worm my horses I never use the same thing back to back...I will use one brand one time and then a different brand the next , go back to the other brand and vice versa..I also worm mine every 3 months...don't know if worming that often can hurt them or not ?

Ok, stop giving her dewormer monthly! All you are doing is building up a resistance to the dewormer in the worms so they'll won't be killed by the dewormer.

Have a fecal done, the fecal will tell you exactly what her worm load is (if any) and then you will know what type of dewormer to administer.

I dont think there is a need to worm a horse every month, IMO i think that is waaay to much. I worm mine four times a year. Once for every season. I would probably call my vet out and maybe they can direct you further. If they need to do something or can suggest a wormer to use. Dont do back to back same brand wormer, if anything the worms might have just become ammune to the wormer. They have different brands for different reason, and that help kill the certin worm or egg for that time of the year. So switch them up. Hope that helps!

Agreed- a fecal will tell you exactly what she is carrying unless she has picked up a parasite so new she isn't passing it in her stool yet.

Also be aware that not all dewormers are alike or cover the same parasites. Different wormers will generally cover different types of parasites so be sure to check what the wormer you are using is good against.

I also wouldn't be worming monthly. If you were treating her for a parasitic infection according to a doctors standards you might give something for a few months until she is cleared since some dewormers are used once a month for a few months according to the doctor...

Another vote for once a month is too much. Our barn does every other month deworming per vet school's orders. Even that seems too much to me, but I suppose the vet who suggested it has his reasons

MissKatie 07-21-2012 08:37 PM

I agree, you have made her immune to that wormer by giving it to her so many times so often. Try use a different one every second time you use it, and only worm her every 8 weeks (or two months).

I would use Wormalicious Waffers. It is a new product, it is horse wormer in a treat type form. You don't have to mess with wormer tubes anymore. Ands it is not much more expensive than a tube of regular wormer. Their website is

I was worried that once a month was too much, but my sister-in-law and the vet said that I should worm monthly until she's 1 year old. Her babysitter, who's a 30+ year old pony mule gets wormed four times a year. After I saw what came out of my baby I wormed Miss Maude ahead of time with Pyrantel and if she did have worms, I didn't see any. I'll have a fecal done on Monday and I'll ask the vet again about worming less often.
With my dogs I never worm without fecals and my dogs had worms only once in 12 years. Only one of them tested positive, but I wormed all of them just in case.
I am concerned about the toxins in wormers, but I was told that there is no way around it with horses. How do I kill the eggs on the ground?

I'll try the waffers. My baby is easy to give paste to, but her babysitter hates it.
Should I give her Fenbenzadole next?
Why didn't the Ivermectrin work? Was it because I gave her the same thing back to back? And how in the world did she get full of worms when it seams like I was worming too often?
