K9 Advantage works

We had been having trouble with fleas when our dog. I had tried various other flea treatments, but none of them seem to work to eradicate all of the fleas. After reading the reviews,I had hopes that K9 Advantage might help. I’m glad I took the chance. One treatment was enough to kill all the fleas off my dog was in days. And they stayed off. I’m relieved to finally found a flea treatment that will work as promised.

Tried %26 True

I prefer an oral flea treatment as I don't want pesticide in my own bloodstream from the topical getting on everything the dog lays on (%26 then I touch). But I have 1 dog that can't take oral treatment. So I've used Advantix for 12yrs. I do bathe him exactly 24hrs after application to avoid it transferring around my home.

I have used this product for a couple years now. It has always been effective at preventing and treating fleas and ticks. I'm not *********% sure about the biting flies, but my three year old Catahoula bulldog is an indoor dog and only goes outside to go potty or about three times a week to socialize with other dogs at a leashless dog park nearby. I haven't noticed any biting flies swarming him at least. I have used other flea/tick treatment, that one from Walmart as well, costing $5-$6 for a three month supply, and discovered that brand wasn't as effective after seeing a tick on my dog and increased scratching four days after applying that flea/tick treatment/prevention. I was wanting to test it's efficacy based on the very cheap price and won't use it again. Lesson learned. The price of this flea and tick treatment is very affordable, and it truly works. I have used it long enough to know it works. If anything, give it a try and see for yourself.
