Bayer Animal Health Advantage II Extra Large Dog 6-Pack

I have been using advantage products for over 10 years and both cats and dogs and it works wonderfully! Both the cats and dogs were located in the south where there are a lot of sand fleas and ticks. Never one single problem. All the hype about fleas becoming immune to it, is just hype to encourage you to buy ingestible poison for your dog to eat to kill the fleas. Commonsense alone should tell you there’s something wrong with that picture…

I used to work at a vet clinic, with resident pets and rescues. They treated the pets monthly, always with Advantage II. It's the most effective OTC product for killing fleas (as well as larva and eggs, so you don't have to worry about more hatching). I buy the XL Dog size and split the doses between a large dog and 2 cats. Treat your pets every 28 days or so and you'll never have to worry about an infestation in your home.

Good product for my animals

We have used Advantage for our dogs and never had a flea on any of them! This is a wonderful, easy to use product that works - we are near woods and still not a problem. Thanks to Amazon for a great price and super fast shipping and packaging!

as long as you apply it twice a month.

had a flea problem that frontline couldn't seem to stop, its been 3 weeks now and my little dog is growing back her fur that she had lost because of the fleas, vet said I could reapply after 2 weeks if needed, but so far so good

I've tried every brand (cheap, expensive, spray, pill) and we just COULDN'T control the fleas our Dogs always brought in every summer. My cat is allergic to fleas, and every year she would get sick sick sick :( but since we switched to Advantage II we haven't had a problem AT ALL! in two years! my cat has gained so much weight and is healthy for the first time in her 6 years of life! I'm so glad we finally found Advantage!

Put it on my cats a couple days ago and it seems to be working pretty well. I followed the recommendation of the other posters on here and my cats didn't hurl up their intestines, so that's a good thing. We'll have to wait and see in another week if there are any fleas left. Will post again then and give update.
