…I use Trifexis for fleas and heartworm. I know Callie is completely against it but it's got a pretty safe track record…
A heads up on Trifexis for those that have flea allergic pets- critters have to bite the host animal for Trifexis to do its job. If your pet is allergic to fleas, you don’t want that.
For me and mine I'm "against" it -- but at the same time, it's getting frigging difficult to figure out how to deal with fleas.
Micksmom is absolutely right -- part of my problem with it (and with anything systemic) is that the flea has to bite the dog for it to work -- if you've got a flea allergic dog that just starts the whole cycle rolling no matter that the flea dies "eventually". My first dog was flea-allergic -- and oh, the agony she went thru with just that one bite.
But my major problem with Trifexas/Comfortis or anything with spinosad is that spinosad (a/k/a Comfortis -- but the drug that's added to milbemycin in Trifexas) -- as indicated on their own website -- can be a serious problem for any dog that may be prone to seizures. It kills by making the fleas seize to death.
For anyone who has ever loved a seizure dog that massive worry is that the animal may "cluster" -- meaning seizures that won't stop. And it can happen on the first seizure or after years ... or maybe never. So now I'm loving another borderline-seizure dog, the idea that spinosad triggers literally seizures until death occurs? I'm no "flea-rights person" (meant to be tongue-in-cheek) but honestly I don't even want a flea to die that way.
One of the ways I make the decision of what to use is to find out *how* the drug does what it does. In the case of ANY pesticide -- how does it kill the pest and not bother the dog. (This was the lesson hard learned by the veterinary community with ivermectin and the whole "can't use it on herding dogs" thing -- because in their initial testing they only used greyhounds.)
I know the vast majority of people only want 'something that works' -- and I understand that. But I also spend a great deal of time helping folks who have dogs with IMHA, and the guilt so many feel because they question if this or that chemical they gave the dog triggered the disease.
So I'm not trying to be a royal p.i.t.a. but just to give folks enough pause to think "Hmmmm" ... and let them draw their own conclusions. We've reached a point with "warnings" in our daily lives where most of us ignore them (or we'd never get thru the day). But then when we DON'T and something happens? The guilt is unreal.
