Worming issues? Opinions/ideas?

***First off...vet has been called (3 times actually), so please don't suggest that I speak to my vet. I'm just looking for information.


Decided to worm 2 of our foals today. (Pandora and the TB filly) (both are 5 months old appx 300 lbs measured by weight tape.) Gave them the appropriate wormer. Within an hour to an hour and a half, I noticed the TB filly laying down. I went over to try to get her up. She didn't want to get up and when she did, she'd just walk away from me and go down again. She did this 4 times before I called my husband over. (it's his brother's filly, so he deals with any of her needs)

She was kicking her back feet, rolling, and showing general discomfort (honestly it looked like she was trying to make "snow angels" in the dirt.) I figured it was colic by the symptoms except that she is on a hay diet only. (CRP grass hay..nothing fancy) No grain..no grass. I'd also never heard of a foal colic-ing..much less a foal on an all hay diet.

While waiting to get ahold of the vet I called two horse ladies whom I know..but couldn't get ahold of either one.

Finally got ahold of the vet. Part of me was worried that the wormer was bad or I'd given the wrong dosage. Vet assured me my dosage was ok, and that colic shouldn't be an issue. Husband gave the filly banamine. Vet agreed..then had us give penicillin as well. Vet said he thought she was having issues due to the wormer maybe killing off a bunch of worms at one time (?). Said to keep an eye on her through the night and call if she goes down again.

Anyone experience this? Know what it is? Would love some insight into this

Anyways..the other filly that I wormed was fine. Showed no signs or symptoms of distress or issues.

That is disconcerting. I would wonder if she has a sensitivity issue to that particular dewormer. Just out of curiosity what kind of wormer did you give her? I guess you wont know for sure until she is dewormed again, do you switch worming products every time?? You may want to look into putting her on probiotics for a spell post dewormer...

Ivermectin wormer.

Hmmm...do you think it possible that she did have a large load of worms?

We certainly have experienced this in cats. When we worm the kittens that we get from my hubbies pap...they almost all get very sick afterwards. Belly aches and crying. In 2 days, it passes with a huge load of worms.

Is the banamine helping?

Heres another random thought. Ivermectin kills lots...but the one thing that came to mind was threadworms. When they are being hit with wormer, they can be very painful for a horse. They don't live in the gut but in the connective tissue in the neck, chest, and legs. Our vet warned us when we were treating a rescue for threadworms. He said to start buting the day before we wormed and to continue for several days after. I guess it can cause some pretty painful symptoms.

Just an idea!

Thanks Corino!! Will be keeping an eye on her for sure. Just in all the horses I've had, I've never seen this happen...so was hoping for some more insight in case someone else has experienced it.

The first time I ever dewormed my foal (at 45 days per vet's recommendation) he got cow-patty poop aftertwards. And I thought he didn't look like he felt well afterwards, but it could just be me worrying too much. (I know I really dreaded giving him dewormer for the first time.)

He didn't roll or act colicky, just looked a little listless. I dewormed him again about a month later (to get everyone on the same schedule) and he was fine the second time. I used Ivermectin both times.

So I don't know. It does sound like she had a reaction to the deworming, otherwise it would be kind of a coincidence, wouldn't it?

Ivermectin is one of the stronger dewormers, but is pretty safe to use as long as you don't overdose them too much. So it shouldn't have caused an issue, but it sounds like it did.

Have they ever been dewormed before, or was this the first time? If it was the first time, then maybe worm die-off was what gave her colic symptoms like the vet said. It would make sense. But if they were dewormed previously, then they shouldn't be that wormy I would think???

This was her first time she was wormed. And now that you mention it, the one time I saw her poop, it was more like cow patty poop.

PS. Your foals are around 300 lbs at 5 months? My guy is 365 at 3 months. He is a Foxtrotter/ QH cross. And a rotten little handful too! Anyway, I guess he is going to be big!? Everyone tells me that! He is my first foal, so I don't know what is typical and what isn't.

I bet the worms weren't happy when the dewormer hit them, and that made her tummy ache!

Bump? Anyone?
