Bayer K9 Advantix II (11-20 lbs) 6-doses

I changed from another brand, because it was not very effective in getting rid of fleas, making my dog miserable. Since switching to Bayer K9 Advantix II I no longer have this problem, It not only kills the live fleas, but also the flea larvae, plus it helps to repel mosquitoes and flies. My dog is a lot happier too!

This exact same package goes usually 40 to 50% more expensive when purchasing it from the local vet's office here. I don't know if the prices are similar elsewhere but for us this was a no-brainer. We compared the first package we bought from the vet and this is the exact same product, only cheaper by far. It works great too! Our dog loves it as well! At least he loves the lack of fleas. LOL

I have used this flea and tick product for years, and this was a great price and a large enough package to last me a few months. I have 2 dogs that I use it on.

Was using Frontline Plus and recently I couldn't get rid of the fleas on my Shih Tzu. Was using CanadaPetCare.com in purchasing my Frontline Plus and several users were commenting the product was useless and possibly a fake. CanadaPetCare is not even in Canada, but is run out of the UK by East Europeans - all of which led me to suspect the low price and quality of the product. So I switched to Amazon and K9 Advantix II and the fleas disappeared after the first dose. Will stick with K9 and Amazon.

Received the package in a timely manner and the product was the size and amount we had ordered. The reason I docked the item a star is that neither my husband or I could locate a Best By Date on the product. It was nowhere to be found on the box or on product inside.
