    1. Bayer Advantix II Flea & Tick Prevention – Best Overall

    Bayer Animal Health

    Check Price on Chewy

    We recommend Bayer K9 Advantix II as the best overall choice for flea and tick prevention. This topical solution is applied once a month year-round. It works on immediate contact by killing any harmful parasites on your dog before they have an opportunity to bite. This method ensures that no harmful diseases will be transmitted to your dog.

    This veterinarian-backed prevention product protects your dog from ticks, fleas, chewing lice, mosquitos, and biting flies and stops fleas from leaving behind flea eggs and flea larvae. Bayer K9 Advantix II starts working within 12 hours of application and lasts for 30 days.

    We found that the overwhelming success of Bayer K9 Advantix II is what earned its top place on our list. However, since it is a topical solution applied directly to your dog’s skin, there is a possibility of a negative reaction. Be aware that your dog may suffer from side effects, or the product simply may not be effective for your dog.

    • Most effective product on our list
    • Vet recommended
    • Once-a-month application/year-round protection
    • Kills pests on contact before they bite
    • Kills and repels a wide variety of parasites
    • Works quickly within 12 hours
    • Last 30 days with each dose
    • May not be effective on some dogs
    • Some dogs may experience side effects

    2. Vet’s Best Flea & Tick Home Spray – Best Value

    Vets Best

    For the best dog flea & tick prevention for the money, choose the 100%-certified natural Vet’s Best Flea and Tick Home Spray. Made with chemical-free essential oils, this spray can be applied directly to your dog or your puppy of over 12 weeks, as well as around your home as needed on affected surfaces, both indoors and outdoors.

    This spray kills on contact and is effective on fleas, flea larvae, flea eggs, ticks, and mosquitoes. You can use it to counter an infestation or as a preventative measure. Since it’s made with only natural ingredients, you can use it around the whole family without concern that you’re exposing them to harsh chemicals. However, keep in mind that skin irritation can still occur on humans and dogs with this product.

    Since this product is a spray, you’ll need to reapply it frequently to maintain its effectiveness. Also, while this spray may smell appealing to you, your dog may disagree and refuse to cooperate.

    • Great value
    • 100% natural ingredients
    • Apply on dog and multiple surfaces
    • Kills pests on contact before they bite
    • Kills and repels a wide variety of parasites
    • May cause skin irritation in humans and dogs
    • Frequent application necessary
    • Dogs may not like smell

    3. TevraPet Activate II Flea & Tick Prevention – Premium Choice


    We chose the TevraPet Activate II as our premium choice for flea and tick prevention. This product contains the same three active ingredients as found in our first-place pick, K9 Advantix II. However, you’ll pay less per month with the TevraPet. Also, unlike Advantix II, which is a monthly purchase, you can buy a four-month supply of TevraPet. Plus, TevraPet is waterproof a day after it’s applied.

    TevraPet repels or kills on contact before pests can bite, keeping your dog healthier. This topical solution lasts 30 days and is applied once a month for year-round protection from fleas, flea eggs, ticks, biting flies, and mosquitoes. However, unlike Advantix II, it does not seem to guard against chewing lice.

    As with all topical solutions, the effectiveness and potential for side effects varies from dog to dog. We found that while Advantix II has more satisfied customers, TevraPet works well for a significant number of dogs. Considering its lower price, you may want to give it a try.

    • Effective for most dogs
    • Lower price per month than similar products
    • Waterproof
    • Kills on contact
    • Kills and repels a variety of pests
    • Last 30 days with each dose
    • May not guard against chewing lice
    • Potential for side effects
    • May not work on all dogs

    4. Hartz Topical Flea & Tick Prevention


    For another even more affordable monthly topical solution, consider Hartz Topical flea and tick prevention. For a low price, you’ll receive three easy-to-apply, single-dose tubes for a total of a three-month supply.

    This Hartz product protects your dog year-round from fleas, including their eggs and larvae, deer ticks, and mosquitos. It kills these pests on contact before they bite to better protect your dog. This fast-acting formula offers 18 days of protection from mosquitos and 30 days of protection from fleas and ticks. It does not guard against chewing lice or biting flies.

    Again, the effectiveness varies, and the potential for side effects is prevalent. We found Hartz to have less success than similar products. Also, you and your dog may not care for the chemical odor emitted during application.

    • More affordable than similar monthly topical solutions
    • Year-round monthly protection
    • Kills or repels most pests, including eggs and larvae
    • Kills on contact
    • Potential for side effects
    • May not be effective for all dogs
    • Strong chemical odor
    • May not guard against chewing lice or biting flies

    5. PetArmor Flea & Tick Prevention


    If you’re looking for a monthly topical solution promoted as highly effective against a variety of species of ticks, then you may want to consider PetArmor.  This product, which comes in a three-month supply, protects against specific ticks, including brown dog ticks, American dog ticks, lone star ticks, and deer ticks, as well as adult fleas and chewing lice.

    PetArmor states that it uses a vet-quality formula that’s waterproof and fast-acting, with results within 24 hours for fleas and 72 hours for ticks. Although it’s applied monthly, we learned that its effectiveness fades as the month progresses. Also, this product may leave an unsightly white residue on the spot of application.

    Keep in mind that topical solutions may cause side effects in your dog and may not work effectively for all dogs. PetArmor may not kill pests on contact, allowing your dog to possibly receive a bite. Also, be aware that this product does not kill or repel flea eggs and larvae and is not listed as effective against mosquitos and biting flies.

    • Effective against a variety of species of tick
    • Vet quality formula
    • Fast-acting results
    • 3-month supply
    • Effectiveness does not last the entire 30 days
    • May leave a white residue
    • Potential for side effects
    • May not be effective for all dogs
    • Does not guard against mosquitos and biting flies
    • Not designed to repel or kill flea eggs and larvae
    • May not kill pests on contact

    6. Advecta 3 Flea & Tick Control


    With similar active ingredients as our top pick on this list, Advecta 3 flea and tick control employs a topical solution to protect your dog from fleas, ticks, biting flies, lice, and mosquitoes. It kills fleas in all life cycle stages, from adults to eggs and larvae, preventing re-infestations for up to four months.

    For an affordable price, you’ll get a 4-month supply. We learned that this product remains effective for the entire 30 days. It also works fast at providing relief and killing pests within 12 hours of application. Advecta 3 claims to be a waterproof and fragrance-free formula. However, we found that it does have an odor when you apply it.

    Despite being similar to Bayer Advantix II, albeit lower in price, we found that Advecta may not provide as successful results — namely, that it may not kill pests on contact. It can also cause side effects in certain dogs.

    • Similar active ingredients as Bayer Advantix II
    • Repels and kills a wide variety of pests
    • Kills flea eggs and larvae
    • Affordable 4-month supply
    • Effective for all 30 days
    • Fast results
    • Waterproof and fragrance-free formula
    • Odor when applying it
    • Not as successful as Bayer Advantix II
    • May not kill pests on contact
    • Potential for side effects

    7. Beloved Pets Flea & Tick Prevention

    Beloved Pets

    A 100% natural and organic monthly topical solution, Beloved Pets flea and tick prevention is safe and ideal for pregnant dogs and puppies over 7 weeks old, as well as for dogs with allergies or pets suffering from an illness.

    Made with natural essential oils, this product comes in a 3-month supply and offers fast results. It protects against fleas, ticks, mosquitos, and biting flies. However, it does not kill or repel flea eggs and larvae, which could lead to a second infestation. It also doesn’t seem to kill on contact.

    As with most natural products, we found moderate success with this product’s overall effectiveness. There seem to be fewer incidents of side effects with these natural ingredients as opposed to chemical-based topical solutions.

    • 100% natural and organic ingredients
    • Ideal for pregnant, allergy-prone, or sick dogs
    • Can be used on puppies older than 7 weeks
    • 3-month supply
    • Kills a variety of pests
    • Fewer side effects than chemical-based products
    • Limited success and effectiveness
    • Does not kill or repel flea eggs and larvae
    • May not kill on contact

    8. Adventure Plus Triple Flea Protection


    We chose the Adventure Plus triple flea protection as our penultimate pick because it does not offer tick protection. Tick bites can lead to serious health conditions in your dog and transmit Lyme disease.

    However, if your dog is suffering from fleas, we learned that this product works as effectively as our top pick. Adventure Plus does use many of the same ingredients as Bayer Advantix II, which may explain its success. However, you can purchase Adventure Plus for a more affordable price.

    This product offers triple protection from adult fleas, flea eggs, and flea larvae, as well as from lice. This waterproof, fast-acting formula can have results within 12 hours of application and prevent future infestations for a month. Again, we must note that effectiveness varies and that topical solutions may cause adverse reactions.

    • Successfully kills and repels fleas and lice
    • Affordable price
    • Kills and repels adult fleas, flea eggs, and flea larvae
    • Waterproof
    • Fast-acting results
    • Does not offer protection from ticks
    • Not effective for mosquitos or biting flies
    • Effectiveness varies
    • Potential for side effects

    Buyer’s Guide: How to Choose the Best Dog Flea & Tick Prevention Products

    Before you decide which flea and tick prevention to purchase for your dog, take a moment to read through our buyer’s guide. We go over the different types of products you can buy to offer your dog pest relief and protection. We’ll also cover what high-quality products should have in order to be effective. Finally, we’ll share our tips to keep those pesky parasites away.

    Topical Spot-On Solutions Versus Other Methods

    Most of our list features topical spot-on solutions and for good reason. These products, in which you apply a liquid dose of solution to the center of your dog’s back between their shoulder blades, work the most effectively. High-quality topical spot-on solutions tend to remain effective for the duration of the month. Of course, you’ll need to remember to apply it on time once a month. Also, these products tend to add up to a higher expense. Plus, be aware that your dog may suffer from skin irritation or worse as an unwanted side effect.

    Other methods of providing flea and tick protection include sprays, powders, and medicated collars. Depending on how much spray or the amount of powder you use at a time, you may or may not save money. Sprays, powders, and collars also tend to lose their effectiveness quicker and with less consistency. You may not realize one of these products has stopped working until it’s too late.

    Must-Haves for Every Flea and Tick Prevention Product

    When deciding on a product in which to invest your money and time, be sure it supplies certain protections. For best results, choose a product that offers to kill and repel a wide variety of pests and most importantly, does so on contact. The lower the chances of your dog being bit, the lower the threat of transmitted diseases. Also, look for waterproof products that clearly state the length of effectiveness and quickness of relief.

    Lastly, if your dog has sensitivities or a health condition or if you’re concerned about exposing your family to chemicals, look for natural products. Though slightly less effective, you will gain peace of mind.

    Tips for Pest Prevention and Protection

    Products for flea and tick protection are essential for helping your dog remain healthy. However, Sydney from Cuddly.com says that you can help these products’ effectiveness with a few easy steps. First, limit your dog’s exposure to wildlife animals. Fences and keeping your dog on a leash should help maintain healthy boundaries from areas teaming with pests. Inside your home, be sure to wash and keep your dog’s sleeping areas clean to avoid creating a place for pests to flourish.

    Year-Round Protection

    Flea and tick protection, as well as guarding against other parasites, must be a year-round endeavor. However, by taking steps to eliminate exposure to pests and by applying effective products to your dog on a frequent and regular basis, you can help keep your pet safe and healthy.
