I'm pretty sure Lacey hasn't been wormed in a while (and she's rubbing her tail and not keeping a great weight on enough food to make the other horses in her pen fat, and she used to be hugely overweight so I know she's not a hard keeper) so I'm thinking I should do that. I had expected my trainer/BO to do that because Lacey was technically completely hers until July when we decided to both half own her. But I also had other expectations that evidently haven't been done...
I called her today about when the last time she was wormed was but I don't think I'll hear back from her. We have horrible communication issues and I only see her about once every few months. Generally I end up texting her son and he finds whatever I need to know out for me. >.<

Anyway, so my questions are:
  • If none of Lacey's pasturemates have been wormed on a regular schedule, is it futile to worm Lacey at all or does it really make no difference? They're holding weight well and stuff...
  • Since I don't know what she was last wormed with (maybe it doesn't matter) what should I start her out on? Hopefully it's nothing too expensive...
  • How often should I worm her after this first time?
  • I suppose I'll need to know her weight, is there a specific brand of weight tape I should look for? I'd really like one that has weight on one side and height on the other (my old trainer had one of those, it was cool) but I don't know what that's called...

Yes i would worm her even if her pasture mates are holding weight, its the first thing that is easy to rule out as the cause

I really like this tape

And i would start with Zimectrin gold

Hiya! Okay some answers to your questions. If they can't remember, worm her. It will take alot to over dose and harm the animal. Wormer is not expensive. We have an Orshelsns store that sells a tube for $6, it works as good as the ones for $15.

Worming her doesn't effect the other horses in anyway. They all have their own schedules probably. Any kind of wormer will do the trick. Get the paste in the tube, really simple. =]

Depending on the wormer, I have had the vet say every 3-5 months.

Actually, if you have a Weaver brand halter that fits Lacey, it will say 'Small' horse and give an estimated weight. Wormers don't have exact weights. They go like 500, 750, 800, 1200.

She probably weighs in between 600-800 pounds, so just give her 750. Giving them a little too much is no big deal.

Hope that helps!

Surprisingly enough, my BO's son just texted me back and said that Lacey was dewormed in the middle of July. So she probably doesn't need it again yet...I would think?

Huh, maybe she's just not getting enough food. And I guess her udder could be dirty...That could make her rub her tail, right? Huh. Weird horse

Any ivermectin paste is your best bet, it's the only deworming medication that effectively destroys virtually every type of parasite, and also doesn't hold a resistance for horses (they don't build up a tolerance or immunity to it).

As for weight, based on her pics, I'd say she's between 800-900lbs. My Arab mare is 14.3hh and somewhat stocky and she's chunky at 950lbs right now.

As for weight/height tapes, you can buy them at any single tack or feed store you can imagine. They ALL carry them. Heck, there was a time we used to get free ones when we bought so much feed!

But definately, if she's looking wormy and under weight I'd give her extra dewormer. A lot of it can be wasted either by leaking out the sides of the mouth or by them spitting it out. Except for the 800lb pony we have, we gave all our girls the full 1200lbs worth of dewormer and they range in weight from 950 to 1150.

I hope God tells her to smash her computer with a sledgehammer.

If you dont think its worming issues causing her to be under weight the next thing i would check is if she needs her teeth floated

just talked to my vet today about this.

i like to worm 5-6 times a year. equimax at least twice (once around now/fall), and maybe a powerpack once a year or every two years. she said you can give the other kinds whenevery. i prefer once every two months.
