Help keep your pal pest-free with the Capstar Flea Tablets for Dogs. Each tablet contains an active ingredient called Nitenpyram that’s effective in eliminating fleas in dogs and puppies. The fast-acting formula starts working within 30 minutes and has been proven to be more than 90% effective in eliminating adult fleas within just hours. That means less itchiness and discomfort for your pooch, much faster—and without the mess and odors of a topical solution. Just give the tablet as directed, and let the formula do its work. A single dose should do it, but it’s also safe to keep giving daily if your pal gets infested again, until all the fleas are gone.

What is Capstar for Dogs?

Capstar is an oral flea treatment for dogs and cats.   It comes in tablet form that you can either give to your dog or hide in their food.  Its formula quickly kills adult fleas that have taken up residence on your pet.

Capstar is available for dogs, puppies, cats, and kittens over four weeks of age. Pets must weigh at least two pounds (0.9 kilograms) or more.  Capstar tablets for dogs are available in two formulations – for dogs 2-25 pounds, and dogs 26-125 pounds. Capstar tablets for cats are available for cats 2-25 pounds.

How Capstar for Dogs Works

The active ingredient in Capstar flea treatment tablets is Nitenpyram. This is an insecticide that kills fleas but does not harm your pet. How it works is your pet quickly absorbs the nitenpyram from the Capstar tablet into their bloodstream. When any adult fleas living on your pet or in their fur bite through their skin and draw blood, they then ingest the nitenpyram, which kills the flea.

Capstar tablets last in your dog or cat’s system for around 24 hours. This means if your animal is heavily infested, you can repeat the dose 24 or 28 hours later.

Ideally, especially if you have given your cat or dog a pill or tablet mixed in their food, be on food watch to make sure it goes down. If you are unsure whether your dog or cat has swallowed their Capstar pill, don’t give them another dose right away. Wait 24 hours until you give them another.

Capstar for Dogs: Benefits

There are a couple of benefits of using Capstar as part of your flea management regime. Capstar tablets are different from some other types of flea treatments in that they begin working in under half an hour. Because they are an oral tablet, they also don’t leave any chemical residue on your pet’s coat or around your home.

  • Capstar is quite fast acting. Your dog will absorb the active ingredient in the Capstar tablet within as little as 30 minutes. It stays in their system for around 24 hours.
  • Capstar tablets have no flavor. If you have a dog that is fussy about the taste of tablets it will be easier to administer or hide in their food.
  • Capstar is safe to give to pregnant or nursing cats.

The effect of flea infestations on your pet is not just about making them itch and scratch. These little parasites can spread other diseases such as tapeworm. Fleas on dogs can cause flea allergy dermatitis, and fleas on cats can cause miliary dermatitis.

How Flea Treatments for Dogs Should Be Used

Flea treatments for dogs and puppies aren’t just about killing the adult fleas on their body. Although, obviously, for your pet’s comfort and sanity getting rid of them from their body is a necessary task! Fleas are agile and can jump from pet to pet, and place to place. What’s more, most of their lifecycle happens away from the body of a host animal.

After a flea lays eggs, they usually drop onto your floor, bedding, carpets and so on. From there, pupa and larva develop and lie in wait for the next warm-blooded host to jump onto when they are ready!

Flea treatments should also be used to treat the areas in your home and yard where flea eggs, flea larvae, and pupa develop. Household fleas are sneaky things. They can live not only on your pet but also in your bedding, carpets, flooring, and furnishings.

Always use flea treatments according to the manufacturer’s instructions, and use the correct dose for your pet. If you have any specific questions in relation to your pet, dosing, or how treatment may interact with antibiotics vaccines and the like, ask your veterinarian for advice.

If you’ve got more than one household pet, you should be giving all of your animal’s regular flea treatments. Adult fleas can, and do, jump from pet to pet! Even if you’ve only got one animal that has visible signs of having fleas – treat them all!

Flea Treatment Options

Flea prevention, of course, is always going to be better than a cure! There are a few flea treatment options to help with the prevention of a flea infestation. There are also options for getting rid of fleas if you do find them on your pet or in your home. Some of the various flea control products include:


Flea collars are infused with an active chemical ingredient that is slowly released onto your dog’s skin. They are commonly used as a preventative measure. Some collars also have formulations to help manage ticks as well.

Topical Solutions

Also known as spot-on treatments, topical solutions are usually applied to the back of your pet’s neck or their spine. There is a range of formulations. These may help protect your pet for a number of weeks or months. They may also target fleas at different stages of the lifecycle.

Oral Medications

Oral medications like Bravecto are given directly by mouth to your pet or mixed in with their food. Some products are chewable flavor tabs, while others may include heartworm preventative medication. Some oral flea treatments are daily, others are for monthly or three monthly use.


Usually administered by veterinarians, flea injections prevent the female flea from laying eggs and reproducing.


Flea shampoos are a short-term option to kill adult fleas on your dog. They will not kill fleas at other stages of the life-cycle or elsewhere in your home.

Powders and Sprays

Powders and sprays are other short-term solutions for killing adult fleas. Some are also formulated to kill immature fleas and ticks. You’ll also find flea and vacuum powders for use on your carpets and furnishings.

“It works. Great for a quick knock down. Wish it was easier to administer, but the pet that needs it the most is almost impossible to give a pill”. Wanda, customer

“The fleas will die. All of them. All at once. Then they will fall off wherever; almost all at once … understand it kills adult fleas, not the eggs, so we gave our dog one, waiting three days then another pill. I have never seen anything work this well. Lisa customer
