II Medium Dog, 4 pack

This is our 2nd box of flea medication for our terrier mix, Krypto. It works as well as the other more expensive one we used to use. I don't like the idea of applying "poison" to anyone, including Krypto. However, I use this during the spring and summer months on him with no ill effects. One thing I like about this is that it's easy to apply. I go over and scratch behind his ears with one hand while emptying this behind his neck with the other. It's more effective than powders and shampoos.

I did a ton of research and found out that this brand is the topical that disables and kills flees the fastest. As far as I can tell, that’s true. As soon as I put it on my dog, she had incredible relief from the flea infestation from hell in our yard and house that we just cannot seem to eliminate. Highly recommended.

Frontline works like a charm, just like always. I usually grab it at the pet store, but busy-mom life says “click, order, done”—delivery straight to my door, zero hassle. Bonus: we don’t even have a flea problem, so it’s peace of mind for me and my pets. Easy win all around. 🐾✅

I have used Frontline as long as I can remember, but for some reason its lost its effectiveness so I thought I'd give this a try. After a lot of research about all the various side effects of different medications (pet armor, frontline, Advantix for k-9's) I decided to go with Bayer Advantage (Advantix is for dog's but harmful if exposed to cats) since my 12.8lb Chinese Crested (Powder-Puff= has tons of hair) best friend is a cat this product was most appealing. I had a recent infestation of those little super fleas; you know, the ones that can hold their breath for 15 minutes and escape a pinch from your fingernail and possibly the blast from a nuclear bomb, yes those ones. I treated him in everything I could imagine including prolonged flea baths using Dawn Ultra, sprinkled Boric acid on the carpets/couch, made tiny little flea deathtraps and vacuumed incisively for two months straight all the while started using this product and low and behold the little effer's will literally falling off him. Forget Frontline, this stuff works!!! And the price is very friendly on your wallet. Word of advice, use this product BEFORE the flea season and make sure to prevent infestations from ever happening otherwise you'll be like me, feeling horrible watching your pup scratch non-stop not being able to focus on anything, giving three baths a week as well as bombing your house to rid yourself of the super fleas from hell who'll eventually develop a taste for your blood. Also, if your pup is small enough you can buy the large breed doses and get yourself a little dropper and ration out how much you pup actually needs...I googled it is something like 0.8ml so you can measure it out and reuse the leftover.

Keeps the fleas, ticks etc. away. Great alternative to revolution.

I recently tried the Advantage II Medium Dog Flea Treatment for my furry friend, and while it does offer some level of protection, I can't help but feel it falls short in certain aspects. On the positive side, the convenience of a 6-month supply is appealing, and the application is relatively straightforward. My dog didn't seem bothered by it, and I appreciate the effectiveness in preventing fleas. However, my concerns arise when considering the limited scope of coverage. Advantage II is primarily designed for flea prevention, and while it does that job adequately, it doesn't provide protection against more serious illnesses transmitted by ticks. In my region, where tick-borne diseases are a significant concern, I opted for monthly pills with a prescription from my vet. The decision to switch to a different product was based on the need for comprehensive protection, especially considering the potential health risks associated with tick bites. While Advantage II may be suitable for areas where ticks are less prevalent, it didn't align with my dog's specific health requirements. In conclusion, if you're primarily dealing with flea prevention and live in an area where ticks are not a major concern, Advantage II could be a convenient option. However, for pet owners in regions with a higher risk of tick-borne diseases, it might be worth exploring alternative solutions with broader coverage, potentially involving a discussion with your vet for a prescription-based monthly treatment.

I buy this brand for my cats so picked this up for my son's dog while we pet sit. Easy to use and have not had any adverse reactions on any of the animals we've put it on over the years.

We have a Cairn Terrier. She is about 15 pounds. She had fleas for the first time in 11 years. We first tried a popular flea killer that uses Fipronil. But, many fleas have some resistance to Fipronil, and I could see live fleas on our dog after using this the Fipronil product so I bought the Advantage II. I did not want the extra ingredients to kill ticks, etc... so that is why I did not use the Adnvantix. I applied the first two treatments 10 days apart. The instructions allow for quicker initial back-to-back applications to get a good jump on a flea infestation. After that, we went to once a month. Our dog did not have any side affects that we could see. And, after the first two applications, we no longer saw any live fleas on the dog. One suggestion that I have for those that have a dog with a flea infestation: Shave or cut the fur as close as possible and then give a good flea bath. This will get rid of any eggs sticking to the dog's fur (you've removed most of the fur and washed the rest). Make sure everything is dry before putting on the Advantage and then do not allow the dog/cat to get wet for 24 hours. That's about it. It worked for us.
