    I have been given a horse - he arrived today.

    WOOOO boy, have I got my work cut out for me!!

    This horse is *very* skinny, and I'm told that he is overdue for worming.

    The vet came out today and advised that I go ahead and pick up an Ivermectin paste wormer (any one will do, they're all the same, she said) and de-worm him tomorrow. Cool, I can do that. No worms are visible in his poop, but I know there are plenty other nasties that could be lurking.

    Here's my question: This poor guy's tail is all rubbed and ragged. My first guess is that it is because of worms. So... how long after de-worming, do you think he might stop rubbing???

    (that way, I'll be able to rule out one reason for the rubbin')

    Give it time to go through him, it should have improved within a few days, but it will take a few wormings to get all the nasties out of his system if he is that bad.

    What I would do

    I would absolutely start with a fec count ( http://www.horsemenslab.com ) to see how big of a wormload the horse has, and make a schedule from there. Maybe you have to use someting that takes tapeworm also?

    Good luck with you new horse!

    With a big wormload and known to be overdue for deworming, I'm shocked that your vet didn't suggest an fec. Especially then recommending that you go with Ivermectin. (I highly advise against 'mail order' fec's. They are at least twice as expensive as having your vet do one for you, and less convenient.)

    As far as seeing results from deworming so far as tail rubbing goes, I would give it at least 5 days before deciding that that wasn't the problem.

    Well, I was kind of suprised too, considering there was a big pile of fresh meadow muffins standing by... I guess she either figured that he needed the wormer *anyway* and that her first guess is that the weight problem is most *likely* a result of a food issue.

    She took blood and gave him a general once over... maybe I should get a second opinion/exam from another vet to figure this (and other age related issues) out?

    Well, if you KNOW the horse is overdue, vets around here don't usually recommend fecal counts, and just usually advise you to go ahead and pop them anyways. because EVEN WITH a fecal count, you could still have the other worms there, just haven't reached the egg laying stages.

    It is normal for a vet to recommend what you were told. VERY normal.

    Since Ivermectin also gets bots, it is also the choice of many vets for deworming as well.

    As for a second opinion, no. Your vet is like most other vets.

    You have to usually bring up the fecal count if you choose, but either way, you probably need to deworm regardless. .

    But the fecal count will let you know what type of volume you are dealing with. Depending on the volume and type, ivermectin can be a very dangerous drug. It's not the time of year to really address bots anyway, so that shouldn't be a concern.

    Yes, she will most likely need to deworm, but an fec will tell her the safest approach to take.

    My understanding is that it's probably been about 4 months since the last paste de-worming.

    And then that brings up the question of what type of chemical was used. For example, if this horse was dewormed 4 months ago with fenbendazole, and he was in a really high reinfestation situation, or had only been wormed with fenbendazole (or even a pyrantel) for some time, deworming him with ivermectin could cause enough of a shift to kill him. Especially if he is already in a compromised state health wise.

    Is this the horse that you just posted a bcs question about?

    If so, there's absolutely no way that I would deworm this horse with ivermectin without first getting an fec. I might chance fenbendazole (such as SafeGuard), maybe. That would even be pushing it in my mind. Wouldn't even do pyrantel pamoate, much less Ivermectin.
