I swear by frontline. Growing up I got to spend a lot of time around the vet's office because my father was a vet tech! I loved being ablt to see all the puppies and kittens. It was great. What wasn't so great was when those poor little babies got fleas. Fleas themselves are disgusting. They cause so much discomfort for your cats and dogs... But did you also know the heath problems that come along with fleas? Your pets can get a number of health problems such as tape worms, Bartonella infection, and even Anemia.

Before frontline, getting rid of fleas was extremely difficult. But now, I promise you... within 30 days of application, your pets will be flea free. Just make sure that you treat your home with a premise spray, vacuum often and wash the bedding that your pets lay on. The frontline is all you need for your furry friend . You won't have to do a flea dip or get a smelly collar. Just one quick drop of the mdeication on their skin (in between their shoulder blades) is all that you need..... Because I mean really.... who wants to bathe a cat! lol that never goes as planned does it?

Our vet told us the Advantage was no longer effective against fleas in our area (California) so we are now using the Cheristin. The only downside is it leaves a sticky residue on my cat's neck for several days. An upside is that I can safely stretch out the application from six weeks to two months on our outdoor only kitty. Wish the price was a bit lower but if it keeps her flea free it is worth it.

It works when applied every four days.  But even then, I find some fleas.  The current Vet recommendation is to combine with Capstar.  And all reviewers are reporting success with Activyl.  So goodbye Advantage and thanks for 25+ years of excellent flea control.

After trying another product for 2 months my cats still had fleas.  After placing these flea collars on both cats they were flea free a little over a week.it seems expensive, but it will continue to work for 8 months, so it is worth the price. I will definitely buy this product again.

Great product at a reasonable cost. Got rid of the fleas and all the other unwelcome pests.
Did a better job than the pest people who couldn't resolve the problem.

Well, I don't usually write reviews but my experience with this product warranted one. My parents have two Chihuahuas and they are both infested with fleas. One dog is blonde, so I have been using that as the test case because it is easy to see the black fleas in contrast to her fur. We got the product 5 days ago and the first night I got it I applied the medicine (if that's what you call it) to the back of their necks. I must say that it is very easy to apply, I thought it would be harder but Bayer does a good job at instructing the user through the application process. Anyway, keeping in mind that the product promises that the fleas will be gone within 12 hours and lasts for a month, my dogs were still scratching about 15 hours later. I thought that it might be that they're scratching because flea bites are a killer (I myself, a human, have some flea bites and they are itchy to no end so I could empathize with my dogs). But that's when I saw the black bugs crawling around in the hair of the blond dog and knew that the medicine must not have worked.

I then decided to apply another round of medicine to their necks and waited about a day and there were still fleas crawling around on the dogs. I have come to terms with the fact that this product does NOT work and I would recommend that those who have dogs with fleas do NOT buy it. Trust me, I really wish that this product had worked, then my life would have been a lot easier.

The products seems to work good so far. It has been two weeks and no new fleas yet. BE VERY CAREFUL when spraying the flea repellant. I sprayed my whole house & went back in too soon and got a headache and very irritated membranes in my throat. The can does not give you a time to stay out of the house... all it says it wait for the spray to dry. Give at least 1 to 2 hours if you need to spray a lot!

This was the first time I had ever used the product and I was very pleased with it. I had used another flea product for years and for some reason it just stopped working. I have two cats that stay indoors but I have two indoor dogs that I take outside to use the bathroom and let them walk around in the backyard, so they aren't outside very long but I do keep flea medication on them. I also keep flea medication on the cats just in case the dogs should carry a flea inside. When my old flea medication quit working I found that my all four of my animals became infested with fleas, including my home. I was absolutely devastated. My basement even became infested and they don't even go downstairs. I had bites all over my ankles and the bottoms of my legs and I thought I would go crazy from the itching. I finally got online and after reading all reviews on different flea medications chose this for my cats and the Bayer Advantage II Green for my dogs. I vacuumed like crazy constantly and bought the Raid spray in the purple can and sprayed everywhere, which will not hurt your pets and finally got rid of the fleas within a little over a month. I did find a few fleas on my dogs after about three weeks, although they were barely moving, but I believe they were jumping off the cats because my dogs have very short hair and you can see their skin, so I went ahead and applied the medication one week early on all my pets and haven't seen a flea since. I also believe that because my pets and home were so infested that it took a little bit longer to get rid of the fleas than it would have if they had been being treated all along with the medication. I'm still not clear as to why my other flea medication quit working. Maybe my pets had just become immune to it. I highly recommend this flea medication to anyone looking for a flea killer and it also did not leave my pets' fur greasy like my other medication did. I plan on continued use as long as it doesn't stop working.

I had to wait awhile after we received this product to write a review because it did take a few weeks of baths with this product to see results. Our dog had such a bad flea infestation that topical flea treatment barely did anything.  Her skin was so dry, itchy, and covered in bites that she had literally chewed all the hair off the backs of her legs and her tail until they were completely bald.  We started using the product about a month ago and I have bathed her with it one a week. The fleas are gone for the most part (I do find the occasional one crawling on her), and all the hair has grown back on her legs and tail. I do find that I have to bathe her about every five days or she starts to get itchy again, bit the frequency is worth the result.

excellent product... i used every three days until all fleas were gone from my dog.  It is not a one time product.. but if used every two to three days until all eggs have hatched then follow up with topical or collar.. your pet should be flea free.... I would have ordered this product again but the price keeps jumping and or fluctuating... would love to get it for the $10 i paid in July... went to cheaper priced product... but i did like this one..

Capstar has provided great quick but temporary relief from fleas for my two dogs and cat. It becomes active within the hour after ingestion and lasts for 9+ hours.

Bayer must've perfected a way for this product to expire before or exactly a month after applying it to your pet. I used to be able to go 6 weeks with the old product. I noticed flea droppings on my cat almost exactly a month to the day after applying Advantage II the first time. Now I'm 3 weeks into the second application and it's stopped working. I don't like putting this stuff on my cats any more than I have to, so I'm not happy and I would not buy it again.

Our dog had a few stubborn fleas that the OTC treatments and powders couldn't seem to get rid of. Within 2 days, he was flea-free, and I couldn't be more pleased with the results.

We have two free-spirited cats who will not wear collars.  Any collar, including flea collars, eventually gets pulled off.  Still our cats spend a great deal of time out of doors and were bringing home lots of fleas.  Advantage II was the answer.  They get a dose, high up on the back of the neck, once a month.  With the treatment, our cats now have no flea issues for a good 25 days or so before we notice them scratching or chewing at their fur.  We have been using this product for more than two years and we are completely satisfied, with no flea problems in our home at all during that time.  Advantage II only got 4 stars from us simply because it is so expensive.  With two cats, a six month supply only lasts three months.

I've only been using it for a couple of weeks and my dog doesn't seem to be experiencing relief from fleas. The bottle does say it takes 30 days and I know breyer's yeast is known to help with fleas. I continue to give my dog a pill every day and she loves the taste and looks forward to getting it. I  am using it in combination with Pet Armour Plus.

I read the reviews before I bought this product and I thought they were pretty good, so I went ahead and purchased a six month supply for my two dogs. I noticed after 30-40 minutes the fleas that they did gave were dead or gone!  I was so excited!  Than, two days later, the fleas were back and I again felt helpless for my poor dogs.  I think the product is good for a quick fix but not something to keep the fleas and ticks away all month long.
