    Default How long until I can treat again?

    Mum decided to swap all the cats and dogs from Frontline Plus to Comfortis because we've noticed the cats in particular are still getting fleas even though they're treated every month. However I had just treated Koda with Frontline when she bought the Comfortis. We have since treated the cats and Dodge with Comfortis... and are seeing improvement already (even though you're not supposed to really notice for a while, i was told...)

    Poor Koda is still itching and scratching... clearly the frontline is not working at all anymore... It used to... but no longer...

    He had the frontline about a week-ish (maybe less, I don' remember, I forgot to write it down) ago... so how long do I need to wait until I can give him the Comfortis?

    If he's itching - might as well give it now - says the well informed not-vet.

    erm.

    I think an occasional extra dose is ok - especially if the active ingredients are different. It's not something I'd want to do every month.

    I've heard that frontline eventually stops working or that it's good to rotate years or something.

    I started on frontline and then swapped to revolution. Revolution complicates things because it includes heartworm treatment. And then to swap to something else - I'd need to find the heartworm treatment some other way and probably double dose the chemicals for that.

    I wish there was something I could put on the back of my neck that would stop mozzies biting me...

    Yeah I do feel sorry for him. I might give him a bath to get rid of most of the live ones, which might give him a bit of peace for a while. Then I'll give him the comfortis later when he the fleas come back...
    I don't want to overload him with chemicals :/

    Neither of my dogs are treated for heartworm... Its not very common in this area. I've heard that some collie type dogs, Aussies in particular can be quite sensitive to heartworm treatments, causes a reaction or something. Something to do with the MDR1 gene.

    It has just occurred to me now that I better double check with other Aussie owners whether Comfortis is okay for them... asked that on the other forum. The more I read about Aussies and reactions to parasite treatments, the more concerned I'm feeling Perhaps I should get him tested for the MDR1 gene, just for peace of mind.

    I heard that whatever the active ingredient is in "Ivermectin" (?) - that can cause reactions in some lines of border collies. I guess Aussies might carry the same lines.

    If there are fleas - of course some how you have to treat where they are living in the dirt as well. I've been pretty lucky. Occasionally - I think one arrives with a stray cat but apart from that - no fleas. And the ones that do lob onto my dog - get so ill they're easy to catch and dispatch.

    Fleas are very hard to control on our property... especially over the whole 30 acres! 8 or 9 years ago, my parents used to rear/sell calves as a living, so we had loads of young calves in yards and sheds specifically designed for them. Long story short, fleas took over the sheds to the point that you could walk in there for 10 seconds and come out covered in hundreds of fleas, you had no option but to go and have a shower straight away because there was just so many of them!!

    Despite my parents best efforts to kill all the fleas, nothing worked. So they ended up having no option but to find something else to do with the farm and sell all the calves. They poured oil all over the ground in the sheds to kill the fleas. No one went in those sheds for months. It did kill the fleas, but that just shows how easily a flea infestation can happen!! I react to insect bites and I had scars on my legs for years after that!

    Since then, even though the dogs do get fleas when the treatment isn't given on time. If they're up to date (and the treatment is working...) It seems to keep them at bay.

    According to this Problems with Dog Medications and the MDR1 Gene
    50% of Aussies can carry the MDR1 gene. And apparently its not just Ivermectin, although I think that is the most dangerous one.

    Yikes

    Did they try something like dia something earth? Supposed to cut up insect skeletons? I think its not something I'd want tracked into the house but if it was in flea habitat - that might slow them down a bit.

    Diatomaceous Earth (Absorbacide) - Organic Insecticide Dust 4 kg for Sale Sydney @ Enfield Produce : Pet & Garden Supplies

    Note - it's sold in some cases by the same people who think a disk of metal will stop fleas and ticks. So I'm not sure how much science there is to back their claims or seriously how safe it could be to eat something that cuts up insect skeletons (would this be on a par with eating ground glass?).
