Ivermectin actually will kill any parasite that is a blood feeding parasite. I have the dose chart and if you want to EMAIL me I will send it to you -- it's a differernt dose for everything from heartworm 'preventive' to hooks, whips, and lung worms and the use of it for demodex (just as a comparison, the dose for demodex is almost 200 times (not percent ... TIMES) the dose used for heartworm 'prevention' which kills any microfilaria. That's for Ivomec (the liquid).
It all depends on where you are -- some feed stores carry it, some don't. You can get it online pretty easily. The liquid has a 4 year shelf life -- one time I figured out you could give heartworm preventive to fourteen 75 pound dogs for the whole 4 years and you'd still throw some away -- and that bottle is between $35 and $50 depending on the market.
No you CAN NOT give it to herding dogs -- "herding" is a huge spectrum - it's genetically a crapshoot -- ok for some, not for others and some breeds routinely use it but **no way** am I going to list the doses here.
It's just plain too easy for the wrong people to get hold of that dose chart, ignore the warnings, give it to their dog and kill them.
ANY dog, theoretically, can either do well with ivermectin or not. It's not just herders, so you do have to be careful
The current problem is that HeartGuard has tried SO hard to make it "ok" for ALL dogs (even herders) that they have made the dose SO small that it's ineffective and it's failing all over the place (particularly we see it here in the South).
It can be cheap -- yes. But you do have to be careful and you have to understand what you're doing. I'll be glad to send you the info if you EMAIL me -- don't pm me (it's not confidential enough for me). I'll email you back and copy you the amounts.
I almost killed my own sheltie mix with ivermectin many years ago -- I didn't realize then the "herding dog" warning. I learned MY lesson and I'm always very careful. But that's why I won't just cut in the dose chart here - I'm just too concerned it can be mis-read, mis-used, and mis-understood. It's not rocket science but you just need to be responsible with it.
Didn't mean to scare you -- but I know many think I'm over-cautious with this. You can also find the dose chart if you look in the "Pill Book Guide to Medications for Your Dog and Cat" (last pub 1998 - Dell Reference Books). You can still get that on Amazon and it's an amazing little book.
The good part about the Pill Book Guide is it actually tells you HOW the drug works. That explains, in essence, HOW it works in the body and why it's a problem for some dogs rather than others. If you've ever loved a herder, you know they "think different" than most other dogs -- and it's the very fact tha they're wired a bit different that makes it all make sense.
