Flea pills are oral insecticides that help to combat, treat, and prevent flea infestations in dogs.

Veterinarians often prescribe different flea pills, and each has a different active chemical ingredient that uniquely targets fleas.

Some flea pills kill adult fleas, others kill larvae, and some inhibit a flea’s ability to flea eggs.

Knowing which part of the flea life cycle is the dog flea pills targets is essential for effective flea control, so read the label carefully and talk to your veterinarian.

Types Of Flea Pills For Dogs

The Merck Veterinary Manual lists the following chemical compounds in flea pills that are most effective against fleas:

  • Afoxolaner
  • Fluralaner
  • Nitenpyram
  • Spinosad

Most of us have only heard of these compounds by their brand names, but it is useful to know the active ingredients during your research.

If your pet is infected with these little critters, you need to know what to look out for in tick and flea control products.

How To Use

If you want to cure your dog of fleas and ticks, consider the treatment. Oral medication (flea pills) should usually be taken daily until the infection has disappeared. However, local treatments can be administered once a month and can last up to 30 days.

Are There Cats at Home?

Dogs are not the only animals that can be infected by fleas and ticks. Cats can do that too, and they can pass on cat fleas to your dog. It is important that when you treat your dog against fleas and ticks, you also treat your cat to prevent them from passing on fleas and ticks after the treatment is completed.


Although current treatments provide relief almost immediately, they are not as effective as oral medication.

Because a veterinarian prescribes flea pills, they are a stronger and more powerful form of treatment that causes fleas and ticks to be killed.


There is no preference for curing fleas and ticks in your pet, rather than what you think will be the best form of medication for your dog.

Remember, check all the factors we mentioned above and ensure that the best flea pills for dogs you choose are suitable for your pet.

Both Dogs and Cats

If you are looking for a treatment that affects both dogs, while curing cats is a topical treatment, this may be the best option for you.

Oral medication prescribed by a veterinarian has a different dosage for cats and dogs and varies depending on their age and weight. However, topical treatment is applied to the skin to be safe for both dogs and cats.

Age of Your Dog

Your dog’s age will play an important role in determining whether topical oral medication treatment is the best form of treatment for your pet. Depending on brand and ingredients, local treatments can usually be given to pets from 7 weeks. However, oral medication is given when your pet is usually 14 weeks or older.

Flea Pills for Dogs Vs. Topical flea treatments and Collars

Flea pills are just one option for flea treatment and prevention.

Topical flea treatments, flea collars, shampoos, and environmental insecticides are also options to help you tackle a flea infestation.

The decision to use a pesticide/insecticide is up to you and your veterinarian. Floor resistance to certain products can play a role in this decision-making process and safety concerns or personal preferences for topical flea preventives and flea collars.

Pre-existing medical conditions, your dog’s age, and whether it is pregnant can also help determine the right flea product for your dog.

In some cases, a fast-acting flea pill that kills fleas within a few hours may be part of a flea allergy dermatitis treatment plan.

Your veterinarian may have a fast-acting preventive flea pill to relieve your dog’s symptoms or recommend a freely available flea pill, such as Capstar, in addition to a monthly preventive.

Frequently Asked Questions (FAQs)

What if My Pet Still Has Fleas?

Although preventive measures against oral fleas effectively kill adult fleas, they do not kill new flea eggs and larvae.

These flea eggs and larvae invade your garden and home and lead to infections if they are not treated.

If your pet takes a flea preventively and you still see many fleas, you may need to treat your home to get rid of the problem.

Products for controlling fleas in the home, including foggers, sprays, and powders, can help.

Do I Need a Vet to Get Flea Pills?

Flea measures have changed considerably over the years. The flea dust that your local hardware store used to sell may not be the best choice compared to some of the more advanced options of today. As a customer, it is difficult to navigate pharmaceutical companies’ promotional material and thousands of conflicting websites about flea pills.

Fortunately, you don’t have to make a decision yourself. Your veterinarian knows a lot more about the different options and can guide you to the most effective option for your dog.

More importantly, your veterinarian is aware of possible side effects and medication interactions between flea pills and other preventive agents and prescriptions.

Your veterinarian can let you know if there is an aptitude for side effects of the breed and if there is anything else in your dog’s medical history that may be relevant.

What Are the Different Types of Flea Treatments for Dogs?

There are a few types of flea treatments for dogs. We have maintained spot-on treatments and oral medicines because they are easy to buy and manage. Curious about what else is available?

  • Flea collars contain insecticides that repel or absorb fleas in the thick layer of dogs to kill fleas. The last one we found varies from six to 12 weeks. In the end, we didn’t review flea tires because they all contain at least one of the potentially harmful insecticides that we have avoided.
  • Flea shampoos use powerful insecticides and are generally only needed for a serious infection. (They are also much messier to use than a spot-on or oral treatment.)
  • Flea sprays get stuck in oils on a dog’s skin. They work like on the site but are more diluted and must be applied to the entire body as often as once a week. This is much less convenient than spot-on treatment, which usually only needs to be applied once a month for the same benefits.

Why Are Flea Pesticides Sold According to the Weight of the Dog?

Manufacturers of flea and tick pills for dogs prepare the dose with a different concentration of the active ingredients. That said, the pills with the least concentration are suitable for lightweight dogs (puppies). While you will note that the medication intended for the larger dogs will have larger amounts of the active ingredient.

In general, these concentrations depend on the weight of the dog. That’s why you have the weight category for flea and tick pills for dogs.

Future Flea & Tick Prevention

Thank goodness fleas can be prevented. After choosing the best flea and tick pills for dogs, follow any additional steps recommended by your veterinarian.

In most cases of flea infestations, you must also treat your home and garden for fleas, along with other household pets, and you must stay on top of your flea and check a preventive schedule to make it effective to keep.

Finally, you must ensure that your dog does not receive an unnecessary overdose of medicine because the ingredients used in these flea and tick pills for dogs can have side effects if you give it too much to your dog.
