The Best Flea Drops for Dogs

Flea protection for your dog should be considered as essential as food, water, and shelter. Fleas and ticks are not only irritatingly itchy; they can also infest your house and transmit diseases. Fortunately, there are many effective flea protection products such as collars, shampoos, ingestible pills, and flea drops.

We’ve reviewed dozens of products to find the best flea drops for your pup. While many of the products have similar features (e.g. monthly spot-on treatments), they differ in price, chemical composition, and even effectiveness. What works for a Husky in Oregon may not work for a Lab in Texas. There can also be allergies and sensitivities to be mindful of.

If you’re interested in other helpful flea treatments for your pooch, then check out our reviews for the best shampoos and the best flea medicine. And make sure you read up on what our Vet recommends to get rid of the pests as well.

Our Top Pick: Bayer K9 Advantix II

For an excellent all-around choice of flea drops for any sized dog, you can’t go wrong with the Bayer K9 Advantix II. Unlike some other products, the Bayer formula is designed to kill and repel ticks and mosquitoes in addition to fleas. Your dog will appreciate the K9 formula as it kills the tiny bugs on contact — not after they bite the skin. This is not only more comfortable for your pup, but it also reduces skin irritation, itching, and helps prevent the spread of any diseases.

Bayer K9 Advantix II is a once per month topical solution that is easy to apply to two or three spots on your dog’s back. You can also purchase different doses and concentrations depending on what size dog you have. Bayer makes K9 Advantix II for all sizes from 4 lbs. to 55 lbs. or more. This is a monthly treatment, so you only have to reapply every 30 days. The formula is also waterproof for your pooch that loves to swim or play in the rain.

Keep in mind that the K9 Advantix II is for dogs only — it is a poison and can be highly toxic to your cat or other outdoor animals. You should also take care to apply the formula as directed as many reviewers have noted their dog became ill after ingesting some after application.

While most reviewers have found K9 Advantix II to keep their dog flea and tick free, a few have found that this formula isn’t effective for them. If that’s the case for you, then keep reading to find some other great products that will work for your pup.

Bayer K9 Advantix Key Features:

  • Kills through contact, so no biting required
  • Kills all flea life stages
  • Also resistant to ticks and mosquitoes

Who Should Buy Flea Drops for Dogs

The most obvious reason to buy flea drops for your dog is to prevent and/or to treat your pup for fleas. If you see your dog incessantly scratching, you can usually see the small pests if you pull back some fur. If your dog spends a lot of time outside, then preventative flea measures are essential.

But drops are just one type of flea treatment — you can also purchase oral medications, collars, shampoos, sprays, powders, and dips. While each type has their own advantages, drops are popular because they are easy and effective. You simply place a drop or two under your pup’s fur — usually behind the shoulder blades — and treatments last for several weeks. A single drop can protect the entire dog because the active chemicals travel through your dog’s sweat glands. This is also why the treatment can’t be washed off.

The main drawback of flea drops is that they can be toxic if ingested. This is why it’s important to apply the drops exactly as stated in the instructions, and you should keep your dog secluded from other pets and children until the product has dried. Young puppies are generally not able to be safely treated with flea drops either. Always check with your Vet prior to initiating a flea treatment to see what would be the best approach for your pooch.

Important Features to Consider

Here are some of the top features to consider when purchasing flea drops for your dog:

  • How long the treatment lasts. One of the advantages of flea drops over some of the other treatments is that one application can last for 30 days or longer. Since the drops spread through your dog’s sweat glands, you don’t have to worry about constantly checking and reapplying treatments.
  • Doses per box. The price for various flea drop applications can vary substantially, so it’s always a good idea to check how many doses you get per box. If one treatment costs twice as much as another that you are considering, don’t write it off if you get double the doses.
  • Ingredients. Check out the ingredients and run them by your Vet to make sure that there is nothing that raises any red flags. Some of these chemicals can be toxic for certain dogs, other pets, and even children. With so many different types of treatments, there are bound to be a few that will be safe for all the small creatures in your house.
  • Natural or synthetic. There are many effective treatments if you prefer natural products over synthetic. Just make sure you check out the reviews to find out how effective they are and how powerful the odor may be.
  • Age and size. You definitely want to make sure that you purchase the appropriate product for your pup’s age and size. Many of these applications provide three or four different concentrations depending on how much your dog weighs, and many flea drops can’t be given to puppies younger than 7-8 weeks of age. Again, check with your Vet if you have any questions about this.
  • Other pest treatments. Some flea drops also protect against mosquitoes, ticks, chewing lice, mites, etc. If your area has a high concentration of these other annoying insects, then it may be worth spending a few extra dollars to ensure your pet is comfortable and protected from these pests.

Frequently Asked Questions

What are flea drops for dogs and how do they work?

Most flea drops are mild insecticides that are toxic to fleas, ticks, and sometimes mosquitoes, lice, and other small pests. While the toxins are deadly to the small insects, they are generally safe for dogs over 7-8 weeks of age. You have to be careful to keep your pets from ingesting the chemicals, however. Typically, you apply the drops on the back of the dog’s neck where she can’t lick it off, and you then keep her away from other pets and small children while the treatment dries.

Flea drops work by spreading through the dog’s sweat glands so that the entire skin surface is protected. The treatment will kill the fleas within a few hours. Some of the treatments require the fleas to bite your dog in order to consume the poison while some work on contact.

How long does it take flea drops to begin working on dogs?

Generally speaking, most of the flea drop applications will begin working within 12 hours. This gives the treatment time to absorb into your dog’s skin, spread through the sweat glands, and begin working on the fleas. The drops won’t kill the fleas right away, so it may take up to 24 hours before you start to see real signs of improvement.

How often do you apply flea drops for dogs?

You can apply most flea drop applications every 30 days, but this will vary depending on your treatment of choice. But note that you should always follow the instructions and avoid applying flea drops more often than allowed. These treatments are dangerous chemicals and can cause serious illness if you apply too much or too often.

Can I reapply flea treatment early?

No, you definitely shouldn’t. Applying too often can make your dog sick, so make sure to follow the package directions. If the drops aren’t working for the entire length of the treatment, then consult your Vet to see what other alternatives might work for you and your pup.
