K9 Advantix Flea, Tick & Mosquito Prevention for Large Dogs 21-55 lbs., 2-Monthly Treatments

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.

I've used this brand before with another dog, so I know it works well. It is easy to apply and you only need to use it once a month. At the time that I purchased it, it was around $15 for two applications, with it only needing to be applied once a month. As such, it will hopefully get me through flea and tick season without needing to buy more. And even if I do need to buy more, it won't cost much and won't take long to receive it, so it makes it easy.
