The 11 Best Flea Sprays For Dogs

You know the sensation when the temperature begins to rise. You observe a dandelion sprouting here and a bud forming there. Saying farewell to winter and hello to warmer months is invigorating.

As with everything, spring has its drawbacks, such as the arrival of insects. Some regions are not as fortunate to even get a winter vacation. Controlling these annoying parasites may be challenging. It appears that once you see one, they are immediately everywhere.

No one wants to deal with a flea infestation, and your dog is no exception. Therefore, BestForPets (bestforpets.org) gathered the best flea sprays for dogs that we could locate in order to review them for you.

Below, you'll find our honest reviews of each product, which will save you hours of research and help you choose the best one for your dog.


Adams Plus Flea and Tick Spray – Overall Winner



Adams Plus Flea & Tick Spray is our vote as the finest flea and tick spray for dogs. There are several reasons why it deserves its place. It is safe to use the spray on your furniture, your pet, and your carpets to kill both adult fleas and flea larvae.

It is a reliable brand that gets the job done. As soon as the spray is applied to the fur, the fleas die on contact. Even after the spray has dried, new fleas that attach will be exposed and perish. Fleas, larvae, and eggs are eradicated for up to two months.

You do not need to completely soak their fur, but you should be generous with the treatment. In conjunction with the spray, Adams also provides a wash for maximum flea control. It smells strongly like alcohol, so be sure to apply it with adequate ventilation.


  • Safe for domestic usage
  • Lasts after drying
  • Optimal matching shampoo
  • Fleas perish upon touch


  • Strong smell


Flea Spray for Dogs by Vet’s Best – Best Value



Vet’s Pet Flea Spray is the most cost-effective flea spray for dogs if you need effective flea treatment quickly and are on a budget. In addition to eliminating fleas, it eliminates disease-carrying parasites such as ticks and mosquitoes.

It is a cost-effective, natural, plant-based product, making it an extremely appealing option. It contains essential oils, mostly peppermint oil. It is odorless of any chemical odors. The scent of mint stays on the animal’s fur and in the home’s upholstery.

It might cause irritation if it comes into touch with the eyes; thus, use caution while applying it to sensitive regions. One concern is that while it is effective as a prophylactic, it is not as effective when it comes to killing on contact.


  • All-natural
  • Aromatic scent
  • Affordable


  • Not fast functioning
  • Can irritate delicate regions


Wondercide Flea Spray for Dogs – The Best Available Option



Wondercide Flea Spray is our premium product if you want the most effective flea control on the market and are ready to spend a little more. Although it may be more expensive than others, the product’s quality may make it worthwhile.

First, it is effective for cats and dogs. This is fantastic if you’re seeking for a product that can do both without requiring you to purchase separate items.

It offers a long-lasting, fresh lemongrass aroma after usage. It is a mixture of natural essential oils, making it completely safe for your dog or cat to consume.

It does not appear to be as effective against ticks. Therefore, if you are a frequent hiker or your dog spends a lot of time outside, it may not be as effective as a prophylactic.


  • Organic ingredients
  • Wonderful scent
  • For dogs and felines


  • Expensive
  • Less effective against ticks


Flea and Tick Spray by Hartz



Hartz Flea & Tick Spray did not make the top three in terms of efficacy, but it still has lot to offer. It is designed to kill fleas and ticks on contact for up to seven days following application. Additionally, it is safe enough to reapply regularly as a preventative.

This product is harmful to cats and should not be administered to them. However, this is acceptable for puppies older than 12 weeks. If your dog suffers from dry skin, the mixture contains aloe to keep the fur silky and hydrated.

Because this is not an all-natural product, there is a chance that your dog will react negatively to it. Before vigorously spraying the fur, you may wish to test the product on a tiny area of the dog’s skin to determine whether it causes any adverse reactions.


  • Seven days of performance
  • Added aloe for sensitive skin


  • May have adverse effects on specific dogs


Flea and Tick Spray from TropiClean



The TropiClean Flea and Tick Spray helps relieve your pet of bothersome fleas. This smells strongly like cinnamon. It is touted as citrus, which can be detected, however the lemongrass, cedarwood, and clove are overpowered by cinnamon.

It seems to eradicate fleas gradually, although reinfestations did occur. Therefore, it may not be as effective on larvae as advertised.

However, it appears to be an effective repellant against parasites. Although it may not immediately destroy the eggs or larvae, it is effective against newly-hatched fleas.

This may be applied on the coat and is soap-free. Therefore, you should not worry about it being harsh on your pet.


  • Soap-free
  • Repellent


  • Lacking effectiveness against larvae and eggs


Frontline Spray for Fleas and Ticks



Frontline Flea & Tick Spray is an additional option to explore. Frontline has produced pet products for many years and is one of the most well-known brands in the industry.

Their reputation for controlling parasites predates them. This product can be used on cats and dogs as young as eight weeks, the smallest age recommended among these products.

Unlike other sprays, this one not only repels ticks and fleas, but also a broad variety of other parasites, such as mange-causing lice and mites.

Because it contains chemicals, it may be dangerous for pets with sensitivity. Be cautious to read the label and test a small area before applying the product to the entire surface.

It may cause chemical burns in some canines and felines. Additionally, it has an intense alcohol odor.


  • Flea, tick, lice, and mite treatment
  • Use in dogs and cats as early as eight weeks of age


  • Can produce chemical burns
  • Strong alcoholic odor


Flea and Tick Spray from Natural Care for Dogs



Natural Care Flea and Tick Spray is an excellent tool for combating possible infestations. As the name says, it is natural, so it may be used safely around the house and on both dogs and cats.

The recipe contains peppermint oil and clove to effectively kill and cure infestations. It may also be used on furniture and upholstery without leaving behind any residue.

The odor is overwhelming, probably more potent than the rest of our natural offerings. Certain individuals may dislike its potency, and some pets may be sensitive to its scent on their fur.

When compared to the other four products, this one did not appear to be quite as beneficial. This is another one that had little effect on ticks.


  • Natural
  • Uses essential oils
  • For dogs and felines


  • Unproductive against ticks
  • Strong smell


FLEA Spray for Dogs from Pet Naturals of Vermont



The Pet Naturals of Vermont FLEA Spray is an honorable mention, despite not being the finest product we could locate. It is safe for use on dogs and cats of any age, which is positive.

The repelling claim made about this product is deceptive. It may keep fleas and ticks away, but it will not eliminate an infestation if you have one. This is a prophylactic strategy, not a universal remedy.

Aside from that, it has a soft perfume with no harsh, chemical-like aroma. It is safe for use on home goods including bed linens. Although you should avoid getting it in anyone’s eyes, it is otherwise safe for dogs and children.


  • Smells good
  • Excellent precautionary item


  • Not effective against pests
  • Not effective against larvae or eggs
  • Only preventative


Bayer Advantage Spray Flea and Tick Treatment



The Bayer Advantage Flea & Tick Treatment Spray is restricted to canines older than six months. It is inappropriate for cats and other animals. It includes the cat-toxic ingredient pyrethrin.

This is only for healthy dogs. If your dog has sensitive skin, is pregnant, nursing, or is elderly, you may want to avoid this product. It appears to be effective at killing fleas on contact. It appeared that fleas began to die as soon as the skin was sprayed.

Although it looks to perform well, it is not ideal for every circumstance. Be sure to read the full label before usage.


  • Fleas are killed on contact


  • Only for dogs older than six months
  • Toxic to felines and other animals
  • Not suitable for pregnant, breastfeeding, elderly, or sick canines

How to Choose the Most Effective Flea Spray for Your Dog

Putting any chemical on your dog should be done with extreme care. After all, just like people, dogs have different ranges of skin sensitivity.

Before applying anything topically to your dog, thorough study and execution are required. You should consider your dog’s health while purchasing a flea spray to combat the problem.

How Does Flea Spray Work?

There are already a variety of flea treatments available on the market. Sprays, shampoos, collars, and pills are available. When used appropriately, flea spray is one of the safest solutions, and it is also effective.

In terms of repelling and destroying parasites, fleas and ticks are commonly grouped together. The spray interferes with the fleas’ neurological systems, forcing their bodies to shut down. In addition, they include chemicals that inhibit development, killing eggs and larvae on the fur.

Fipronil, etofenprox, pyrethrin, and tetrachlorvinphos are typical substances found in flea and tick treatments. Others utilize essential oils such as peppermint, clove, and others.

Which Negative Effects Are Potential?

As with any medication, there are the possibility of undesirable side effects. Allergic responses are possible. This might result in skin irritation, redness, itching, and peeling.

Isooxazoline treatments can result in significantly severe neurological responses, such as tremors or seizures.

Exist Natural Replacements?

Many of the products on our top list are all-natural flea sprays that contain no toxic chemicals. While some of them may not be as efficient as sprays containing chemicals, they are safer for your pet. Typically, natural sprays are safe for dogs, cats, and other domestic pets.

The majority of these items contain essential oil as an active component. Commonly employed oils include peppermint, clove, and lemongrass. They provide your pet with a clean coat and do not leave behind a distinct chemical odor.

How Do You Determine Which is Correct?

Choosing a renowned brand with a track record of success is the initial stage in the decision-making procedure. Keep an eye out for any dangerous substances, like as methoprene and permethrin, in the spray. These have harmful adverse effects and should be avoided if possible.

Before applying it to the entire coat, you should test it on a small patch of skin and observe the reaction.

How Should One Apply?

After ensuring that the product has no harmful effects on your dog’s skin or gastrointestinal tract, you may begin the application process. The majority of sprays require that you wear gloves and spray into them.

Apply the spray to your dog’s eyes, nose, and mouth by gently massaging the area. To limit the chance of eye or mouth contact, you may spray directly on the coat if it is positioned away from the face.


We hope you like these reviews and can make a decision based on our findings. Adams Plus Flea and Tick Spray was hand-selected as the finest flea spray for dogs. It works the best for a reasonable price, and most dogs don’t have to worry about it being too harsh.

Vet’s Pet Flea Spray is a cost-effective option if you’re searching for a flea treatment. It is pleasant-smelling, fully harmless, and effective. While it is not suggested for other pets, it may be used without issue on home materials.

Wondercide Flea Spray is our top recommendation if you don’t mind paying a higher initial cost. This product is created with several beneficial essential oils, smells amazing, and lasts a long time. If you have both dogs and cats, you may use it for both. Although slightly more costly, it may be of greater value.

You alone can choose which of these products, if any, are appropriate for your dog. We’ve taken out the time-consuming steps, so you can treat your pet and fix the problem.
