Product Description

Size: 12-Pack | Color: 23 to 44-Pound

Frontline Plus for Dogs 23-44 pounds, 12-month supply. Frontline Plus effectively targets all stages of fleas. Fipronil collects in the oils of the skin and hair follicles and continues to be released from hair follicles onto the skin and coat resulting in long-lasting activity against fleas and ticks. By effectively stopping the development of new fleas, Frontline Plus completely breaks the flea life cycle.

Customer Reviews

They spend a lot of time outside in flea and tick rural areas.
If you try Frontline and it doesn't work, k9 advantix II might, as it did for me.
Eric D
Now I am applying it every two weeks and still the dogs have fleas.

This review may be quite lengthy, but as an Amazon consumer, I recommend that you thoroughly read and understand this review, as I guarantee it to be worth your time and the health and safety of your pet. Frontline Plus for Dogs when packaged and sold properly (by most Veterinarians and most reputable companies) works as it is described to work. For those instances, I would give the product a 5 star rating. But being that this is a consumer review of Frontline Plus for Dogs for the marketplace of Amazon, I would like to bring a particular experience that I became a victim of, to the attention of the consumer.

Merial produces the product named Frontline Plus for Dogs (of various weights) for US consumers and for the consumers in International markets. Products produced for US distribution are EPA approved. Products for International markets, are not EPA approved. EPA, in this instance, stands for Environmental Protection Agency. This agency sets and enforces rules and standards that protect the environment and control pollution. If a manufacturer produces and distributes EPA and non EPA approved products, it seems like a safer option to administer the EPA approved product.

Here goes the story of how I fell victim to a fraudulent sale of Frontline Plus for Dogs through a Seller / Store utilizing Amazon:

Upon receipt of a Merial Frontline Plus for Dogs product from a Seller / Store on Amazon, the packaging appeared identical to those sold by my previous Veterinary purchase as well as a previous purchase of this product from Amazon directly. While the outside appeared legit, the inside contents had me on alert instantaneously.

Allow me to caveat this review by saying out of 500 plus reviews this is the most difficult to write as I despise having to use pesticides on our dogs. That said, we live in Tick and Flea central, surrounded by deep woods and our bull dogs are in every sense of the word family. That said if you're reading these reviews your dog or dogs are your heart and using these products is a difficult choice to make, but for most of us it's one we have to make.

On that note, it's nice to be among my own kind of folks and it's my hope the following information has some value for you.

Frontline was first put into clinical trials in 1985 shortly after the discovery of it's active ingredient Fipronil. It has maintained the safest albeit not the most effective treatment for fleas and ticks. However, the more effective products pose a significantly greater risk to your dog.

It's a slippery slope, but in evaluating what's best for your dog and offers the most protection at the least risk Frontline and FrontLine Plus are hands down, without question your best bet.

Most tick and flea products contain Premethrin (or related compounds) as the active ingredient. Premethrin is a lethal neurotoxin that flows through the dogs circulatory system and flushes into every major organ - including the brain where it can do dire damage. Although thousands of dogs die every year from Premethrin and the FDA has mandated a minimal use of it not to exceed 750PPM companies continue to use it because it's cheap and effective.

What makes Premethrin so dangerous is that it can't distinguish between insects and mammals including human beings. It's been known to be lethal to cats since the 1970's. Even a slight transfer from dog to cat can result in seizures, brain damage and death.

I've used Frontline on my dogs for years with no problem and I still think it's a fine product. This one star review is based on my most recent experience. I ordered this product through Amazon and received an illegal product via a third party seller. I got Frontline Combo, which is not approved by the EPA for sale in the US, in a Frontline Plus box. The lot numbers on the box and product did not match either, so clearly someone had deliberately tampered with the product. I experienced the illegal sale of a pesticide, product tampering, and mail fraud all in one transaction. A representative at Merial, the manufacturer, told me that this problem is widespread on the Internet and advised me to buy Frontline products only from my vet. I just took a look at the seller reviews and there are a number of us who have had the same experience with this seller, so I don't think Amazon is paying attention. Please be careful about what you are putting on your beloved pets!

My dog is a Chow mix and very furry. Ticks are impossible to find under her two layered coat until it's too late. At first, I tried cheaper brands. They work on ticks but do nothing for fleas. Then my vet recommended Frontline. I later tried K9 Advantix since they claim to also kill mosquitos, but I didn't notice any difference with the little bloodsuckers. And the protection from K9 Advantix didn't seem to last as long so I switched back to Frontline.

Frontline works great for us. My dog is an outdoor dog and our county reportedly has more deer than people. And with deer come deer ticks. I've seen deer in my back yard and my dog's house is very near the woods for shade. And she likes to take the occasional jaunt through the woods. Still I rarely find a tick on her. And when I do, they're usually dead (or soon will be).

I wish I'd known Amazon was selling Frontline for a better price sooner. I've been purchasing only 3 months worth for about $50 from another site for the last 2 years. Very frustrating since before you know it, you're out. With 6 months worth I only have to remember 2 times a year instead of 4.
