What Is the Best Flea Treatment for Dogs?

There is no single answer to this question because there are many factors that play into determining what will work the best. The best flea treatment for dogs (or pets in general) is really based on several criteria. Things like the type of pet you have, your budget, and personal likes or dislikes all determine what is best for one specific person. So let us take a look at some options that would be good for different types of animals and budgets.

Which Dog Flea and Tick Control Is the Best?

Topical Treatment vs Oral Medication

First of all, you need to decide if you want to go with something topical or oral medication. This decision usually comes down to how much you are willing to spend on the product as well as how easy it is to administer.

In general, topical treatments tend to be a bit cheaper because you have less material. In addition to that, they are usually easier to administer as well. With oral medication, there is always the question of getting it into your pet's system and dealing with any side effects from it being in their metabolism longer. This can vary by product but is something you should know going in. The other downside to topical treatment for pets is that some types do kill only adult fleas and not eggs or larvae so a second round may be required if you see new insects on your pet within 30-60 days after the first application. Even so, topical treatments are extremely effective and if you want to go the more natural route there are some good options.

The Best Topical Flea Treatment For Dogs in 2021:

#1 Advantage Multi for Dogs

Advantage Multi is a topical treatment that offers the benefit of killing adult fleas, eggs, and larvae for 30 days. It also kills mosquitoes and treats ear mites if your pet is susceptible to them. This medication is incredibly safe with no known side effects even when used at high doses multiple times per month which makes it great for pets that may be sensitive to other topical treatments.

#2 Frontline Plus for Dogs

Frontline Plus is a topical treatment that has been around for some time now. It kills adult fleas as well as eggs and larvae on your pet within 18 hours of first applying it. In addition to that, it will repel any new insects from coming onto your pet for up to 30 days which is excellent. Frontline Plus also treats flea-borne diseases such as Lyme disease, Rocky Mountain Spotted Fever, and Ehrlichiosis.

#3 K9 Advantix II

K9 Advantix is another topical treatment that kills adult fleas within 12 hours of applying it to your pet. This product also kills ticks which is helpful if you live in an area where dogs get Lyme disease. K9 Advantix also treats and prevents flea eggs from hatching for up to 30 days which is a huge benefit of this product.

The Best Oral Medication For Dog Fleas in 2021:

#1 Capstar for Dogs

This product is also designed just for dogs and offers an effective solution to killing fleas within 30 minutes before they can bite your pet and become immune. The oral medication is especially useful because it not only kills adult fleas but also any new larvae that might hatch from the eggs. This means you don't have to worry about a secondary purchase to make sure your pet is completely rid of these pests after you treat them with Capstar.

#2 Comfortis

This is another excellent oral medication that kills adult fleas and prevents flea eggs from hatching for 30 days. Comfortis does not kill ticks so if your dog is prone to Lyme disease you will need to add Frontline Plus for this (which we saw earlier also kills ticks). The dosage can be adjusted based on your pet's weight to ensure effective treatment without issues.

#3 TRIFEXIS for Dogs

This is another excellent oral medication that kills fleas within 12 hours of your dog eating it. However, the product only lasts 30 days so you will need to make sure that your pet stays on its normal routine in order to receive effective treatment. The product itself is very safe and has only had mild side effects such as vomiting, itchiness, and diarrhoea.

The Best Natural Flea Treatment For Dogs:

#1 Neem Oil

This product is derived from a natural plant and contains a certain compound that interrupts the reproductive cycle of adult fleas. It also has prevention properties in that it helps to keep eggs and larvae from hatching for up to 6 months which means you only have to apply this once per year (if needed). The downside to this treatment is that it can be smelly and oily which could irritate your pet causing them to scratch the area you applied the product.

#2 Cedar Oil

This is another natural product that helps to prevent eggs and larvae from hatching for up to 6 months. It also repels insects like mosquitos which helps keep both you and your pet from being bitten. In addition to that, several studies have found this product to be an effective treatment against both adult fleas and ticks on dogs. The downside of using cedar oil is that it does not kill the existing adult fleas so you will need to add another oral or topical treatment in order to get rid of them immediately.

#3 Diatomaceous Earth

This is a great natural product to use around your home if you have fleas. It has the same effects as cedar oil in that it prevents eggs and larvae from hatching for up to 6 months. However, diatomaceous earth also kills adult fleas by dehydrating them which means you only have to apply it once per year. You can use this product in your yard or even inside your home (if you live in an apartment).

The Best Flea & Tick Collars in 2021:

#1 Seresto Flea and Tick Collar

This flea collar is both effective and affordable. It lasts for 8 months which means you don't have to worry about re-applying for it during the year. Although, the product only repels ticks not kill them so make sure you purchase Frontline Plus (which we saw earlier also kill ticks) if your pet is prone to Lyme disease.

#2 DEWEL™ Pro Flea and Tick Collar

DEWEL™ Pro natural flea collar is the perfect solution to keep your dog free of fleas and ticks - safe, easy and effective. The Dewel natural product does not contain any harsh chemicals or pesticides that may irritate your pet's skin. Dewel`s Flea Collar for Dogs by DEWEL™ PRO is made from 100% all-natural ingredients such as citronella oil and cedarwood essential oil act as natural repellents while also increasing circulation and nourishing skin. Lemon eucalyptus and lavender provide antibacterial and antimicrobial properties that protect dogs while healing and nourishing the skin. This combination makes it a powerful remedy against fleas, ticks and other pests while being gentle on your pup's sensitive skin. In just 24 hours after application, you will start noticing relief from bites and scratching!

Natural Flea Remedies

An interesting discovery among natural pet owners is that lemon-eucalyptus oil seems to be a very viable option for ridding your pets of fleas. Not only does it look like it kills adult insects but also eggs and larvae in a very short amount of time. It has been proven effective when mixed with other ingredients but really shines when used alone. Using this oil alone means that there would be no need to have an additional treatment applied that kills eggs or larvae. In addition to being 100% natural, lemon eucalyptus oil is safe for just about everyone.

Other Natural Flea Remedies

There are several other natural remedies that can be used to rid your pets of fleas and ticks. Most of them were used in the old days before chemical treatments, but have recently been found to kill insects with all their little legs rather effectively. One example is a simple mixture that consists of 1 cup of apple cider vinegar, 3 tablespoons of baking soda, and some water. Mix it up into a paste then add it to your pet's fur. Leave this on for about 20 minutes before rinsing off with warm water. Another treatment uses lavender oil which has been found to quickly kill adult fleas but not larvae or eggs so make sure you don't miss out by only treating the adults.

Once you have decided on what type of treatment to go with, you need to make sure that it is safe for your pet and won't cause them any harm. Also, make sure you know how often you should apply the treatment (once a month or every six months) because this will vary by the product. The easiest thing to do here would be to ask your vet for their opinion on which option they feel would be best for your dog. If you haven't already taken care of this yet then I hope that this information has helped in making your choice!


The best flea treatment for dogs depends on your dog's age, breed, and the severity of the infestation. When in doubt, consult a veterinarian to make sure you are using an effective flea product made specifically for pets.
