So it looks like trifexis is the better option. I do wonder though, for those of you that use it, do you worry about basically "poisoning" your dog in regards to using chemicals to kill/prevent bugs that they don't even have? I'm sure mine don't have any intestinal parasites, but then I'd still be "poisoning" them for critters they don't have, right?
I was trying to say nothing and can't. I will *not* use spinosad (Comfortis) -- I DO use Interceptor (milbemycin alone) and I can't wait for them to come out with a version without spinosad.
I know a lot of folks on here use spinosad. Spinosad "kills" by causing the flea to have seizures to the point of death. It has also been linked to seizures in dogs. I will honestly never be "ok" with a drug that kills that way, particularly one that stays in the bloodstream all month (the milbemycin part doesn't, the spinosad part does).
My pug already battles what they call a "pre-seizurey" condition (she has little "petit mal" twitches that we control with herbs). I've had other dogs who battled seizures. There just is no way I would be comfortable with a drug in any way that owed it's strength to killing seizures (even in a parasite).
Bottom line -- 999.99999$ of us never even think about "how" a pesticide kills pests. If it works and the vet says it's ok, then what's to question? And I'm not saying anyone's vet here is bad. My own regular vet sells Comfortis.
I just can't "go" there if that makes sense.
of pumping them full of chemicals, but what other options are there?
Just last night I typed out a response on the AIHA/IMHA thread about heartworm prevention -- and one of the dogs at question lives WAY up in Canada (not even on the border but hours above the border) -- and she was questioning the use of herbs in place of heartworm prevention. And in that case I had to say "no' to that as well because the herbs at issue (blackwalnut and a few others) are patently *Poison* -- and altho folks have been using them to fight internal pests for ages, I have to say "too danagerous". Dosing is iffy at best and how strong the dog's metabolism may be makes it even more impossible to "dose" accurately and not ncur heart problems with those herbs
My point is this -- you have to take everyhing on a case by case basis. Heartworm prevention, to my mind, is not "pumping them full of chemicals". If you live here in the American South, as I do, if you don't give your dog heartworm prevention, ultimately they WILL get heartworm and if you don't treat it they will die. And for that "prevention" I'm going to use the safest (and the least amount of) stuff I can. So I *must* use heartworm prevention (which again is a misnomer but that's a whole different discussion) --
But altho fleas carry disease, and can actually make an animal anemic and unwell, I don't have to use a chemical "added on" to combat fleas that is, particularly in my personal experience, dangerous from a seizure point of view.
This is where you have to talk long and hard with your vet. Discuss what your particular situation is ... how much of a threat is contained in each option.
For me it's all wrapped up in a bunch of things -- I don't do annual vaccines (just rabies when it is absolutely required), and I don't use anything that is "systemic" (meaning it enters the body system either by mouth or via the skin, and stays there the whole month). In this particular case spinosad is not only systemic, but it's a chemical with a seizure-related means of working, so it's a double "no" for me.
Like I said - I know a lot of folks on here use it, but I won't. I'm hoping I'm not sounding ratty or nasty -- it's not my intent. This is a more-than-usually difficult decision this year because Interceptor's hard to get.
