Dog Flea Medicine Reviews

Dog flea medicine offers protection from nasty parasites that can cause great discomfort to your dog.

But there are so many various products, and they all claim to be the best...

Some provide protection from fleas only, others protect from fleas and ticks. Some can even protect from disease-carrying mosquitoes.

With so many choices, how do you pick the right flea medication for your pet?

Here is some helpful information to assist you in making your selection...

Types of Flea Medications

These medications can be separated into 4 categories. Lets take a look at each one and try to figure out what works and what doesn't…

Spot-on Topicals

You apply spot-on topicals from different manufacturers more or less in the same manner…

Part the hair on the dog's back between the shoulder blades, until the skin is visible. For smaller dogs, apply the entire contents of the tube to this one spot. For larger dogs, apply the contents of the applicator tube to the skin at 3 or 4 spots on the top of the back from the shoulder to the base of the tail.

Of course, you will need to follow manufacturer's instructions for the product you decide to use.

Each spot-on flea medicine comes in different dosages, based on your dog's weight. Make sure you buy the right one.

I review some of the more popular spot-on flea medications lower on this page.

Oral Tablets

Oral tablets are tablets that your dog will need to eat, that is, if you can trick him into it!

They work well but from my experience, it's a lot easier to apply a spot-on medication than to trick your dog into eating a pill. They also have limitations when compared to spot-on topicals.

Flea Collars

Flea collars don't work as well as oral and topical medications. It's best to use them as insurance, together with spot-on topicals or oral tablets. Don't use them as the only flea protection.

Dog Flea Collar Bio Spot® Flea & Tick Collar for Dogs and Puppies is one of the better flea collars and provides protection for up to 5 months.

And as you can see from the name, it provides protection not only from fleas but ticks as well.




Flea shampoosicon don't really fall under the flea medicine category, but they are medicated and can be effective. How effective, depends on the degree of flea infestation.

What I would do is, I would try the shampoo first. If it didn't help, I would add either a spot-on topical medicine or oral tablets, and continue using the shampoo.

Before I review some popular flea medications, let's take a look at how we can get rid of fleas naturally.

Flea Medicine Reviews

K9 Advantix

This is a spot-on topical product that you apply on your dog once a month.

K9 Advantix Tick and Flea Medicine

In addition to fleas, it provides protection against ticks and mosquitoes. While other products only kill the above parasites, K9 Advantixicon also repels them.

You can start using K9 Advantix on puppies as young as 7 weeks and it kills 98-100% of fleas within 12 hours after the first application. It's also waterproof, meaning that bathing your dog will not wash it off.


K9 Advantixicon is one of the best, if not the best, products on the market.

Frontline Plus

This is another excellent dog flea medicine.

Frontline Dog Tick Medicine

Just like K9 Advantix, you apply FRONTLINE Plusicon once a month and it's just as effective. It's waterproof and will also provide protection against ticks.

While FRONTLINE Plus does an excellent job at preventing and killing fleas and ticks, unlike K9 Advantix, it does not provide protection against mosquitoes.

One advantage Frontline has over K9 Advantix is that you can also use it on cats. You can use FRONTLINE on puppies as young as 8 weeks.

I've been using FRONTLINE Plusicon on Bo for several years now to protect him from ticks, and we both are very happy with the results.


Unlike the previous 2 products, Advantageicon works only on fleas.

Advantage Dog Flea Medicine

Like Frontline Plus and K9 Advantix, Advantageicon is a once a month spot-on flea medicine that's also waterproof.

One huge advantage it has over the other products is it's speed -– Advantage stops fleas from biting in 3-5 minutes and kills 98-100% of fleas on dogs and cats within 12 hours of application.




If your dog is suffering from flea bites and needs help fast, Advantageicon is the product to use!


Unlike other products we just covered, Programicon is taken orally (it's a pill) once a month.

Program Dog Flea MedicineIt works, but it's not one of my favorite flea medicines…

Its major drawback is that it does not kill adult fleas -– Program is designed to stop flea eggs and larvae from developing into adult fleas.




Like Program, Capstaricon is an oral flea medicine. That's where the similarities end.

Caprtar Fog Flea Medicine

Unlike Program, Capstaricon kills adult fleas and is fast acting (starts killing adult fleas on your dog within 30 minutes).

Its drawback is that its effect lasts for only 24 hours.

I would use it in situations where my dog may be exposed to fleas for a short period of time only (a dog park, an obedience school, a dog show, etc.). I would also use it if I needed to get rid of fleas really fast.

Most customers who buy Capstar also purchase Programicon, sold separately, to kill flea eggs and larvae for a complete flea management program.

Each flea medicine that we just reviewed is safe and works well. Though it's rare, some dogs may experience an allergic reaction to any of these medicines. If that happens, immediately contact your veterinarian.

Some owners, instead of commercial flea medicines, prefer to use home remedies to kill fleas. If you would like to learn more, visit home remedies for fleas page.
