Advantage II for Dogs is a topical flea control formula that
kills adult fleas and inhibits the flea life cycle at all stages. Adult fleas
are killed within 12 hours, giving your pet fast relief. Advantage II continues
to work for a full month and provides effective protection from lice—all with
an easy-to-apply topical.
Note* See Allivet’s Flea and Tick Chart to refer to which
flea and tick treatment your pet may require.
I remember when the first Advantage hit the market in the late 90s, it was a huge game changer and I've used the product on my various dogs over the years and never had a problem.
This product I bought for my dashaund is for fleas an ticks an I use it on him every month this way I know he is protected. I have been giving it to him since he was a puppy he is now two an I love him just as one of my children
This product works magnificently and they will eliminate the pests menacing our furry loved ones.
I have used Advantage II for many years on many different fur babies. It 100% works and so I don't change.
I have used this product for 12 years with no side effects.
If you are not able to get the oral medication advantage 2 works the best for topical .
Never had a problem with Advantage. I feel secure as a multiple dog owner.
It works well for my cattery.
Heart worm and fleas, that’s Florida! I looked for a product that would deal with all stages of fleas on my older dog, and the Allivet chart helped me make this choice. Thank you.
Great price, and auto-ship service.
Fast and easy. Thank you. I like easy online buying
Good PRice and refills auto matic with a discount!!!
I bought for all the dogs and my cat cuz they have fleas. I want to thank you for fast and easy ordering and shipping. So far so good. Thank you
I have used this on all my dogs and this one works the best, never gets any ticks or anything
This has worked to keep fleas off my dog before and it’s supposed to be non-toxic
It works great
No fleas! Same ingredient as cat (just larger amount) so safer to use with cats in household
I don't love the smell of this on my pets for the first 24 hours but it does work to keep the fleas off. We live in the country with a lot of wild deer and turkey coming through so without this, our pets would suffer from constant bombardment. Highly recommended
great price
This size is the most economical way to make multiple smaller doses for our many cats. We use small oral syringes for the cat doses to measure out the proper amounts based on the cats' weights. We save significantly more this way than buying the cat packages.
Been using this for years, it never disappoints,
Great stuff
I have used advantage to for years on my dogs. I am here to tell you I have never had a flea or tick problem. If something works you continue using it.
Always an easy purchase and excellent price
No fleas ever
Allivet contacts my vet for me!
Nothing works as good as the Advantage II on my dogs.
Low price!
This is the best for dogs that I have ever used and such a good price.
Works fast. Highly recommend. Within 24 hours my dog had no fleas, no digging and scratching.
Advantage has been the only good medicine that works good for dogs that live in the woods
Best price .
Trusted
The Prices are very good.
We have many mosquitos
Great price

Great price! Easy ordering from home!
Works for me.
Good job
I buy Advantage 2 55lbs + and dose it out because I have multiple dogs. I learned this trick working at the local Rescue. That's how they buy it and can treat multiple dogs and different sizes. All of mine are the same size and breed so it's easy.
great flea/tic protection
Very good
I went with Allivet on this product as it was rated well in lots of other places and the local pet stores have recently doubled the cost of the medicine so the better prices here certainly helped.

Great for baby puppies until they are old enough to put on Bravecto.
works well where I live in the mountains of Maryland

This is the best product I have found for keeping fleas under control on our dogs in the mostly warm and humid climate of Florida.
SITE WORKS VERY WELL
Best price for effect flea and tick control I have ever found.
My first order for Advantage II
good price and works well
If you don't have ticks, this is all you need. Same formula, just very different doses, by weight, for dogs & cats. Be sure you know what you're doing. I've used it for over 25 years with good result. NEVER USE DOG TICK KILLER ON CATS OR CATS WILL DIE!
Outstanding product. Does the job w no side effects on my dog.
this was a return because I ordered the wrong thing. Fast easy no trouble courtesy what else is there
very pleased with this newly found service and setting up on auto deliver is one less thing to worry about - very simple, very easy!
an excellent product for fighting fleas. more economical here than local
My dog is allergic to fleas. Not all medication works as well advantage ll.
works great on fleas.
Wonderful product does the job of protecting my dog.
I've used this on my other dogs with no problems. Has always worked.
Getting prescription renewed was easy. You faxed dr and they faxed back same day! Received order in 3 days!
took awhile
Best product
no problems with fleas or tick with this product. my dog is pretty much an inside dog but she could still attract those little buggers if not for advantage 11.
This works really well for us!
USED FOR YEARS W/NO FLEA PROBLEMS
It's affordable and better than similarly priced other topical products. I prefer an oral product but not all will eat it, so I use this for those animals. Lasts about 2 weeks only. Gets rid of about 80% of the fleas.
Good value. I like purchasing from Allivet
hate fleas. This is the only thing that keeps them away!
Great price and service.
My dog is allergic to flea and tick spot treatments. Vet recommended Advantage and a tick collar.
Good flea preventive. We found that this works in our area better than other brands. Needs to be less expensive
I used to use front line but fleas became immuned. Advantage is still working for me.
vet recommendation for dog with special medical needs.
I've been using Advantage for a few years now and it consistently keeps our house flea free.
We use this and Revolution on a rotating basis. Works for us in Florida.
Southern Florida fleas are resistant to all the other topical treatments that I've tried, prescription and OTC. This seems to have done it -- now 48 hours since application and for the first time in MANY months, I do not detect fleas on any of my three dogs. And the price from this site was the best I found (plus quick shipment).
More expensive at local pet store and Amazon charged tax on product.
The best thing about Advantage 2 is that it kills ticks even though it doesn't advertise that it does. One of our dogs had a small tick on her neck last summer but it was DEAD and had not barely latched on. We feel it was the contact with the medicine that did the trick!!
This was highly recommended by my vet as inexpensive and high efficiency flee prevention pills. My dogs are small and only Advantage has doses for dogs smaller than 10b
Best stuff I have found for my dogs. Forget about frontline because this is way better.
I only use advantix for my dogs it seems to be the only product that works correctly and the price at allivet is the best
Works, not a waste of money
While we don't have fleas and only rare cases of canine lice in Alaska, what I like about this is that it is easy to apply, has no obvious effect beyond protection, and meets the requirements for Doggy Day Camp.
Same stuff as the one for cats, and if you measure it accurately using the weight of the cat it is much cheaper.
Need to help my little kitty to be happy and healhly
I Have used for 2 years & will continue to use as we have had no problems with fleas & easy to apply. I'm really pleased with the results! I will use again!
I called customer service(I believe I spoke to Jocelyn) and was extremely satisfied. I chose to purchase from you based on lowest price (including shipping). You also have products that I need. Advantage II for Dogs is the best.
Advantage II is great for the prevention and treatment of flea and lice, it works fast and very effectively
