(3 pack) 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.

This is the only product that works for fleas and I love that it is more affordable and also offered in smaller packs as I have 4 different size dogs. I understand having to have this stuff locked up in the store but it is quite inconvenient to have to find/wait for an employee to come unlock the area in the store so I'm glad I can have it delivered and still get it same day without the hassle. I understand theft is a big problem but I do often get tired of being inconvenienced due to other people's behaviors. (In relation to the items being locked up)
