Have you noticed your dog scratching frequently? While there are many possible culprits, fleas are by far one of the most common causes of itchy skin for dogs.
While you might think your well-groomed canine companion is not a likely target, these tiny pests don’t care how clean your dog is. Fleas are notorious for their ability to easily jump from one host to another. Dogs can catch fleas from playing outside, contact with other dogs, or even from a run-in with a wild animal. And your pooch can come down with a full-on flea infestation of these blood-sucking parasites from the presence of only a single flea.
Thankfully, there are many readily available and effective flea treatments for dogs. Outlined here, you’ll find details on five of the best flea treatments on the market.
Best Flea Treatments For Dogs In 2020
Flea control products have come a long way in the last few decades. After a questionable history of dangerous chemicals, uncomfortable flea collars, and ineffective shampoos, there are now many far better options. Variety, safeness, and effectiveness of more recent products make it easy to find a suitable flea treatment for your dog.
Frontline Plus Flea & Tick
Got a major pest problem? This fast-acting flea and tick treatment from Frontline is formulated with two powerful, fast-acting insecticides. The broad-spectrum insecticide ingredient, Fipronil, works to neutralize and kill adult fleas while the hormone analog ingredient, Methoprene, interferes with the development and growth of flea eggs, larvae, and pupae.
This long-lasting, powerful dog flea treatment is designed to break down all four stages of the flea lifecycle, completely ridding your pooch of fleas and ticks, and even lice, and protecting against future infestations.
This waterproof, topical formula works by adhering to the skin and depositing the active ingredients into the skin glands responsible for secreting sebum, the oily substance that lubricates your dog’s skin and hair. Applied to the skin in one spot, under the coat, from a single-use applicator, Frontline Plus Flea & Tick is easy to use, convenient and effective for a full 30 days.

Nexgard Chewable Tablets For Dogs
Battling something you can’t see? With this oral flea treatment, it’s easier than ever to provide year-round flea prevention for your dog in one simple monthly dosage. Chewable tablets are a great option for fidgety and nervous dogs that sometimes make topical flea treatment frustrating.
These beef-flavored tablets are safe and tasty for dogs, formulated to kill fleas before they even have time to begin laying eggs. After the tablet is ingested, the insecticide part of the active ingredient, Afoxolaner, is transmitted to fleas via the bloodstream as they bite your dog. Each tablet contains enough of the insecticide to keep your dog free of fleas for an entire month.
While you’re treating for fleas, Nexgard Chewable Tablets will also kill ticks and mites. Because ticks and mites are arachnids, not insects, Afoxolaner also contains an acaricide property specifically designed to target and kill various members of the arachnid subclass Acari. This extra part of the chemical compound makes it easy, with just a single chewable tablet, for pet owners to not only rid their dogs of fleas, but also of mites and all kinds of ticks, including black-legged tick, American dog tick, Lone Star tick, and brown dog tick.
You May Notice
You may start to notice more fleas after you’ve administered the tablet. But don’t worry, this fast-acting treatment can have fleas and other pests dropping off your dog’s coat–well, like flies–in a matter of hours. Seeing more fleas or ticks throughout your dog’s coat simply means they are dying and rising to the surface of the hair.
A Few Precautions
Always follow the manufacturer’s included instructions for Nexgard Chewable Tablets and never give any dog-specific flea treatment to a cat. Keep these tablets out of the reach of children.
Most dogs have no serious side effects from Nexgard tablets. Some may experience vomiting, decreased appetite, diarrhea, or dry skin. These side effects are usually not serious or prolonged. However, if your dog exhibits constant vomiting, complete loss of appetite, shaking or tremors, seizures, or wobbling or difficulty walking after ingesting the Nexgard tablet, immediately consult a veterinarian.

Trifexis Chewable Tablets For Dogs
Note: Dogs must have current heartworm test results on file to get a prescription for heartworm medication.
Here a pest, there a pest, everywhere a pest, pest? It can be hard to stay on top of all the different parasites that affect dogs, but Trifexis Chewable Tablets make it easy to prevent and treat flea infestations, heartworm disease, and infections from hookworm, roundworm, and whipworm all in one product.
With two powerful ingredients, Trifexis works as both an insecticide and an antiparasitic medication. The active ingredient Spinosad works as an insecticide and kills adult fleas before they begin laying eggs. The active ingredient Milbemycin Oxime acts as a broad-spectrum antiparasitic, preventing the development of heartworm disease and killing a variety of intestinal parasites.
Designed to be administered once a month, these tablets are an ideal solution for quick and efficient treatment of both fleas and all kinds of intestinal worms that can cause infections and heartworm disease.
Things To Watch For
As fleas are exposed to the Spinosad, they often rise to the top of your dog’s hair, so you may notice more fleas after administering Trifexis. However, visible fleas in your dog’s coat mean the medication is working, and dead fleas are exposed.
You may also need to treat your home for fleas in some cases to prevent re-infestation due to flea eggs and pupae present in the environment, such as carpets and furniture.
A Few Precautions
Follow the manufacturer’s instructions for the correct use of Trifexis and never use Trifexis on your dog without a prescription from your veterinarian.
Most dogs do not experience serious side effects, but some may experience vomiting, diarrhea, overtiredness or weakness, loss of appetite, itching, hives, and swelling or reddening of the skin. If your dog experiences any of these, consult your vet. Other more serious side effects may result if your dog is allergic to Trifexis. This may include: swelling in the face, pale gums, cold limbs, hives, excessive scratching, sudden onset of severe diarrhea, excessive vomiting, shock, seizures, and coma.

Even better, this single-dose tablet also aids in controlling fleas by interfering with flea egg development.
