I have two boxers and I have been using this product. We live in florida and have a pound in front of our house and it really protects them from fleas and mosquitos.
I Have 3 80lb plus dogs. With the canal behind our house we have a lot of mosquitoes. K-9 advantix is the only one that works all month with one application. There is no spraying every 3 days. We also hike in the Florida woods where the dogs are protected from fleas and ticks.
I have used the other name brand and have found the the K9 Advantix ll works better. Vet Depot has the best pricing that I have found and their service is great. That's a hard combination to beat.
I bought this from VetDepot after reviewing a bunch of products on many websites. VetDepot had it for the best price. So far my dog has had no problems with it and it seems to be working great.
My dogs started to refuse to eat the flea medication that you mix in with food. It became such a hassle that we went back to topical. It's great. No more coaxing the dogs to eat their food "all up." Just rub on the medication and go. It works down here in hot, humid Houston where fleas thrive. We used to it before the medications that you mix with food came on the market. Now, we'll just stick with it - easier, effective and less expensive.
