The 15 Best Flea Prevention Products for Dogs

1 Best topical flea & tick medications: Bayer K9 Advantix II Flea Treatment for Dogs

Best topical flea & tick medications: Bayer K9 Advantix II Flea Treatment for Dogs
Key features:
  • Contains imidacloprid, permethrin, and pyriproxyfen
  • Parasitostatic mechanism of action within the first 5 minutes
  • Starts killing fleas, ticks, and lice within the first 12 hours
  • Convenient once-a-month topical application
  • Fully waterproof formulation

Bayer Animal Health has been producing a lot of high-quality veterinary products for a long time and its K9 Advantix II simply carries on this tradition of excellence. The Advantix II’s main advantage is in its fast parasitostatic action, helping stop fleas from biting within 5 minutes of application. While it takes 12 hours for Advantix II to start exerting its killing effect, this is still relatively faster than the average 24 hours of other brands, making it a favorite flea and tick treatment for dogs among serious dog owners.

Unfortunately, K9 Advantix II has not shown any improvements in the duration of its action, mimicking the industry standard of 30 days. It would really be amazing to see advance this further to 60 or even 90 days. Regardless, with easy application and excellent waterproofing, it sure can help protect your dog whether it is a 7-week old pup or a lumbering senior.

What others say about it:

Two English Springer Spaniels who are very active outside and not one worry using this product. Been using this for years and they’ve been sleeping in our bed for years. Needless to say, we don’t have any problems with fleas, ticks, mosquitos, or any critters that aren’t supposed to be in our bed! Very happy with this purchase and will purchase it again.

You can also apply it directly on dogs and pups aged over 12 weeks of age but avoid the eyes and face because it will cause irritation. It cannot be used on pregnant or nursing dogs.

What others say about it:

Highly recommended if you read the label you understand how it works which all you need to do us spray the fleas and you will kill them instantly but it has to be sprayed on them for it to work. Every time I sprayed where the fleas were they died. I combed my dog and sprayed her before we went to sleep and she was able to sleep with me with those fleas on her and after they were gone as precaution I sprayed her before bed until I was able to take her to the vet who checked her for fleas and found none.

My dog is an Australian shepherd mix and we have struggled for years to find a flea medicine for him that is both effective and doesn’t cause seizures.

He even pulled a chunk of his hair out from itching and their was a large open sore. Now a little over a month of having him on this stuff and he is so much better!

This product seems to really calm the scratching, chewing that the cats have been doing. I have 5 indoor only cats, have never in 12 years had fleas till now. For some reason one has more than the others and these wipes really help her to calm down. I use these on 4 of them as the 5th does not like the wipes, but he doesn’t like anything being put on him.

What others say about it:

I have one dog and two cats that live inside but frequent the outdoors during the day. After trying Adam’s Plus instead of the other flea and tick sprays costing over a dollar an ounce, I can say the other’s don’t have anything on Adam’s. We keep a flea trap in an area of our house where our pets spend a lot of time in order to catch the fleas that ride into the house on our pets and jump off before ingesting any of the treatment. Having occasionally found flea’s in it in previous years, we know it works. However, since using Adams flea and tick spray for the last 18 months, we have not found any flea’s in the trap and I am getting ready to order my second bottle of it.

  • Effective against ticks

The pesticide in this product is delivered to your dog in a delicious and chewable beef-flavored tablet that you will have no problem administering to your dog. You can also hide it in their food. It is safe for dogs and pups aged over 8 weeks old and who weigh more than four pounds. The tablets need to be given once a month and will last for the whole period in between.

Each tablet contains 136 mg of afoxolaner which kills adult fleas before they have time to lay any eggs. This interrupts the life cycle and prevents infestation from starting all over again. It is also highly effective at killing several species of ticks that can bite dogs including the black-legged tick, the American dog tick, and the Lone Star tick.

What others say about it:

My golden retriever had a seizure from Simparica. Because we have cats in the house, we did not want a topical for the dog. That left us few options. The vet suggested NexGard because although it is the same family of medicine in Simparica, it is not as fast acting, takes a day or two longer, and based on his analysis of the products, he said NexGard would likely be easier and safer for the dog. So we tried it, and luckily, the vet was right. No seizures with this one.

  • Contains pyrethrins and permethrin
  • Contains pyriproxyfen – insect growth regulator

A highly effective flea treatment is provided in an aerosol spray that will cover and treat 2,100 square feet of carpet, rug, etc. in your home. The treatment is for your home and needs to be used at the same time as another treatment that you apply to your dog.

It stops fleas from developing for up to 7 months giving your dog exceptionally long-lasting protection from annoying pests.

These ingredients also get to work rapidly to reduce the infestation of adult fleas. Then it prevents any newly hatched fleas from developing into the adult stage when they start breeding and jumping back on your dog to bite them. It reaches the fleas around your home so it controls infestations in rugs, drapes, and floor cracks which makes your treatment even more effective. There is no unpleasant odor and the product is not sticky.

What others say about it:

We tried literally every natural approach to flea treatment, and we only had a mild infestation. I could not believe the amount of time I spent vacuuming (3hours+ a day- I was adamant about NOT using chemicals!), but it was all for nothing. One treatment of this fixed everything. One treatment. I didn’t have to evacuate my pets from my house (like with a bomb). I just shut off the a/c for a couple of hours so the spray wasn’t sucked through the return vents of the bedrooms I sprayed (the only carpeted rooms in my house), and shut the doors to keep our pets out. I did open the windows for circulation. Also, I just covered our bearded dragon’s tank with a thick towel. This was 3 months ago. I have since seen fleas on the dog (from outside) but not a single one in the carpet or vacuum. When it says 7 months protection, I believe it!

For owners looking for a powerful product that will both kill fleas and prevent future infestations, the Bravecto Chews would be a wise choice. They contain Fluralaner which is a powerful acting chemical – so you can only use this product on dogs aged over six months.

It kills many species of ticks and all life stages of the flea. Because it is chewable, there is no mess and no unpleasant smell. Most important of all, it lasts for 12 weeks so it requires less effort from dog owners.

What others say about it:

I left town for a few weeks last year and my apartment had some drilling outside and I forgot to shut my windows. Came home a few weeks later and had a horrible flea infestation. I was struggling to get rid of the fleas with furniture spray and dog spray so my vet recommended Bravecto and within two hours fleas were literally falling off him. After that I used a fogger for my house and haven’t seen a flea since!! I highly recommend! One last note, I did have my dog on a topical flea treatment prior and it didn’t stop the fleas once they got into my apartment.

Best Flea Treatment for Dogs: Buying Guide & FAQs

If you go to your favorite pet supplies store you can easily understand why a lot of dog owners, especially first-timers, are at a loss as to which product they should use for their pets. We understand how you feel. That’s why we’ve prepared this buyer’s guide to help you make better-informed decisions related to the control and management of flea infestation, not only in your dog but also in your home.

Why Does My Dog Need Flea Treatment?

One of the questions that most dog owners ask themselves is whether or not their pooches really need flea treatment. The answer is a very straightforward ‘yes’. The best way to help you understand why is to look at the life cycle of fleas.

Fleas are very resilient – they live outdoors and can survive for up to 5 days in temperatures as low as 33 degrees F. Within this period, it can easily catch a ride on your dog’s fur. They don’t fly, but they are mighty jumpers, able to propel their bodies up to distances that are 50 times the length of their bodies.

The adult flea can then lay eggs on your dog’s skin. Throughout the life of a female adult flea, it can lay up to 5,000 eggs, possibly even more. These can fall on your carpet, your floor, or any other surface near your dog.

Within 2 weeks, these eggs hatch and become larvae. These juvenile fleas are particularly averse to sunlight so they are mostly found in dark and humid places such as cracks and crevices on your floor. They also love to hide under your pet’s bedding as well as under your carpets and rugs. And if they get in touch with your pet’s food, they naturally grow into pupae.

The pupa actually just waits for the right trigger for it to come out from its cocoon. These can include vibrations, heat, and increased carbon dioxide levels. All of these actually indicate the presence of a suitable host nearby. When this is triggered, it transforms into an adult flea. All of these can occur within just 4 days although it may take some time for it to transform into its adult version if adverse conditions are present.

So, Why Does Your Dog Need Flea Treatment?

Because every time your dog foes outside, there’s no way of telling how many fleas may have latched onto them. It would be safe to assume that your pooch has at least one.

Once fleas bite, they can introduce microorganisms into the bloodstream and cause a variety of health conditions and diseases. The following are some of the more common diseases caused by fleas.

  • Flea bite dermatitis: This is one of the most common issues associated with fleas in dogs. It develops because of the inflammatory changes that occur secondary to tissue injury caused by the flea bite. The skin becomes reddish and sometimes swollen and very uncomfortable for dogs. And because inflammatory chemicals are released, primarily histamine, these produce severe itching which, when vigorously scratched by your pet, can lead to loss of skin integrity. Cuts occur on the skin and these can become entry points for other microorganisms like bacteria, viruses, and other parasites which can then lead to other health problems.
  • Typhus: Fleas are known carriers of several species of the bacteria Rickettsia which is the principal causative agent of typhus. While the primary target is rats, dogs and humans alike are not immune to its infectious nature. This can lead to fever, joint pain, vomiting, and even muscle pain. All of these can make your pooch sick, will not want to eat, or become depressed.  
  • Plague: The causative agent of plague, Yersinia pestis, is basically transmitted by fleas to rats and other mammals. While the incidence of plague has been significantly reduced, there are still thousands of cases reported every year. Some of the symptoms of plague include fever and severely swollen lymph nodes. The problem is that death often ensues without warning. It is for this reason that pets that are suspected of having plague should be brought immediately to the vet for management. Also, strict isolation must be observed to prevent the spread of the disease.  
  • Tapeworm: The tapeworm Hymenolepis nana has been shown to be carried by fleas, although direct human-to-human transmission also occurs. Dogs can ingest adult fleas when they lick their fur or surfaces that contain tapeworm-infected fleas. Children are especially vulnerable as they can accidentally swallow an infected critter. The good thing is that this infection can be easily treated.  
  • Hemobartonellosis: Bartonella henselae is most commonly found in ticks although it can also be found in fleas. The danger in hemobartonellosis is that the bacteria invade the red blood cells. This disrupts the cells’ ability to carry oxygen and deliver it to the tissues. This leads to anemia which can make your pet lose its appetite, lack energy, and lose weight.

These are just some of the more common health issues associated with fleas. There are plenty more. It is exactly for these reasons that many pet owners give only the best flea medicine to dogs. And you should, too.

Where Do Fleas Hide On Dogs?

Fleas are incredibly and can thrive on any part of your pet’s body. However, they do have the tendency to hide in areas where there is some degree of protection, especially from scratching.

As such, you may want to start looking at the base of your pet’s tail as most dogs cannot scratch this part of their bodies. Additionally, the natural curvature of the tail bone gives these pests some degree of protection. Other areas where these pests can hide in your dog include the neck, the belly, and the chest. The space in between toes on your pooch’s paws can also be excellent habitat for these ectoparasites.

Can I Use Flea Treatments When My Dog is on Other Medication?

It is understandable that you may have reservations about using flea treatments while your dog is on other medication. Generally speaking, you should never combine medications as there is no way of telling what effects will come out of the drug interactions. You should always consult with your veterinarian about what flea treatments are safe for your dog if they are already on medication.

Some more safety tips you can consider when considering any treatment:

  • Read the labels of each product and focus your attention on the drug interaction section.
  • If you wish to combine pesticides for your pet, it is a lot better to combine a flea-only medication with a tick-only treatment.
  • Never give your dog more than what is recommended.
  • Do not double up on your treatments. For example, giving a flea medication on top of another flea medication.

How Often Do I Need to Give My Dog a Flea Tablet?

One of the most innovative solutions in the fight against flea infestation in pets is the development of a tablet form of these flea medications. There are many benefits of flea tablets, pills, and chewable that other forms of treatments simply cannot provide. For instance, these are considered to be more effective than traditional spray-on or topical preparations since there is no guarantee that all of the active ingredients will be absorbed by the dog’s skin. Since tablets go directly to the digestive tract where they are digested and absorbed into the bloodstream, there is a greater concentration of the active ingredient present in the blood. These medications are a lot more convenient to administer, too. Some actually come complete with all-in-one protection that helps protect pets against heartworms and intestinal parasites, not just ticks, and fleas.

But the question most pet owners ask is related to the duration of action of these formulations. Most spot-on treatments require re-application within 30 days, some as short as 15 days while others promise 90-day protection.

Similarly, the duration of effectiveness of flea tablets depends on the brand. For instance, Capstar is known to be a very potent anti-flea medication that can kill these pests within 30 minutes. Unfortunately, it doesn’t last that long. If your pet gets reinfested within the day, you can give another tablet of Capstar. Without additional effort on your part to control the environmental factors affecting flea growth, you’d end up with a more expensive treatment as you will need to give your mutt.

On the other hand, Bravecto’s 90-day protection is spectacular for a flea tablet. While it doesn’t work as fast as Capstar, it is still a lot faster than traditional spot-on medications. If you do use Bravecto, then you will have to give your pet at most 4 times a year.

This is dependent on where you live. If you live in areas where fleas thrive all year round, then you will have to treat your pet for the whole year. However, if you live in an area where these pests display seasonal patterns, then you will only give your mutt these tablets at most twice a year.

Again, depending on the product that you give to your mutt and the prevalence of flea infestation in your locality, the number of times you will give a flea tablet can range from as short as daily to about 3 months.

Tips on Preventing Fleas at Home

Regardless of how aggressive you are in your application or administration of the best flea medicine for dogs or how meticulous you are in removing these critters off of your pet if you are not going to do something about their natural habitat, then you will still face the same problem year in and year out. As we have already explained, there’s no way we can track the movement of these pests from the outside environment to our homes. We often only realize that they have invaded our homes when our pet begins to scratch. By then, many of these fleas would have already laid eggs. Some would already be in their larval and pupal stages. In a few more days, they will turn into adult fleas.

That is why it is imperative that you should also know how to prevent fleas at home. Here are some tips.

  • Start cleaning your backyard. Since they love hiding in crevices and cracks where there is plenty of moisture, you may want to start spraying your backyard with an appropriate pesticide so that these pests are killed even before you or your pet has a chance to bring these inside your house. Covering crevices and cracks on the ground and keeping everything neat and tidy should also help minimize infestation. This also means you have to mow your lawn and keep the shrubs well-trimmed.
  • Safeguard your property by putting appropriate electric fences for dogs that will help prevent the entry of feral animals into your backyard. Remember that fleas don’t just rely on dogs as their hosts. Other mammals are excellent hosts, too. So, don’t give this curious wildlife a reason to be nosy on your property. Don’t leave food scraps or even your pet’s food outside as these are natural magnets for feral cats, raccoons, and other creatures. Also, seal off possible entry points such as crawl spaces, sheds, garages, and even under decks as these can be used by other animals as nests.
  • Call a professional to fog your home properly. Many of the chemicals used in fogging can kill fleas in all stages of development, including the very hardy pupae. These substances can also last as long as 7 months, so it may be wise to plan the fogging so that when it does wear off most of the fleas will be less active. If you have a large property, getting 2 to 3 foggers should do the trick.

Keep your shrubs well-spaced. The more sunlight that gets through to each leaf or any other structure in your plant should help kill the larvae of these pests. Improving ventilation also helps.

Use a pet hair vacuum, sweep, and mop your floors and other surfaces to help remove eggs, larvae, pupae, and even adult fleas. Make sure to reach in baseboards as these critters love the dark. With each vacuum, dispose of the bag immediately. Remember that vibrations can ‘awaken’ pupae and turn them into adult fleas.

Wash the beddings and other items of your pet. Leave these to dry under the hot sun. This should kill these ectoparasites. Include your mutt’s toys.

Tips on Preventing Fleas at Home

The market for flea and tick treatment for dogs is crowded which gives you plenty of choices. However, in order to choose the best product for you are your dog you need to know what to look for. Here are our top tips:

  • Age suitability. Is the product suitable for your age of dog? Some cannot be used on dogs under 3 months or even 6 months. Others should not be used on seniors without speaking to your vet. Always check the label.
  • Coat suitability. Some types of treatment are more suited to a thick coat. For example, you may want to avoid shampoos if washing and drying your dog’s very thick coat is a big job!
  • Household. Perhaps you have young children in the household and would prefer to avoid harsh chemicals. A more natural product may be more appealing to you.
  • Dog lifestyle. If your dog regularly goes on hikes in the forest, they need a good tick treatment.
  • Where you live. Some areas of the country have a bigger problem with ticks and fleas than others.
  • Time. Wipes, shampoos, and sprays are more time-consuming than tablets and chews.
