Bravecto For Dogs Side Effects & Reviews

Ticks and fleas can be worrisome for our pets, and they can spread fast if not kept in check. Worse, these pests can spread diseases to humans as well.

Flea and tick infestation can be difficult to stop once it has started. These parasites are nasty, gross, and can cause your dog and you a lot of trouble.

These pests can breed fast so prompt action is the key. You need a treatment that kills ticks and fleas fast and efficiently

If you want a tick and flea killer that works fast and lasts long, you might want to consider Bravecto.

What Is Bravecto for Dogs?

Bravecto for dogs is a tick and flea protection product designed for our dogs to effectively stop and prevent future infestations. While most similar products only stop tick and flea reproduction, Bravecto kills those already on your dog. 

Bravecto comes in a chewable or topical formulation. The advantage of oral medication is that it’s easier to administer, compared to lotions or shampoos where you need your dog to stay put during treatment sessions. Dogs also tend to lick or rub off these topical products, which greatly reduces their effectiveness.

With Bravecto, all you need to do is follow the correct dosage according to the weight of your dog and that’s it. Each treatment with this product lasts for 12 weeks, making it practical and economical.

What Is the Proper Dosage?

Bravecto, just like any other tick and flea medications, requires a prescription from your veterinarian, and depends on the weight of your dog. Lighter dogs require less of the product, while heavier ones require more. Look at the table below to see which dosage fits your dog.

Weight Formulation Active Ingredient Dosage
4.4 to 9.9 pounds Toy Dog Formulation 112 mg of Fluralaner
9.9 to 22 pounds Small Dog Formulation 250 mg of Fluralaner
22 to 44 pounds Medium Dog Formulation 500 mg of Fluralaner
44 to 88 pounds Large Dog Formulation 1000 mg of Fluralaner
88 to 123 pounds Extra Large Dog Formulation 1400 mg of Fluralaner


As mentioned, each treatment will last for 12 weeks so you’ll need to repeat the dosage after 3 months. If you miss a dose, just give it right away and give the next after 12 weeks.

For the chewable variant, you need to give Bravecto with your dog’s food. For the topical version, the contents of the tube should be administered on the dog’s shoulder blades.

What Are the Side Effects?

All tick and flea medications come with their share of side effects and Bravecto is not an exemption. The product is fully approved by the FDA and its manufacturers spent a lot of money and time to make sure that it is safe for your dog (1). Nevertheless, here are some of the side effects (2) that have been reported by dog owners who have tried Bravecto:

  • Vomiting
  • Flatulence
  • Increased thirst
  • Diarrhea
  • Weakness / Lethargy
  • Decreased appetite
  • Seizures, in rare cases

Although rare, seizures should be taken seriously, and the risks involved should not be overlooked. Take your dog immediately to the vet if seizures are experienced when taking Bravecto.

The rest of the reported side effects might not be life-threatening but still unpleasant for your dog and you. You can get a recommendation from your vet if these show up on your dog.

How Much Does Bravecto Cost?

Although very effective and efficient, Bravecto is pricier than its competitors. Considering that you’ll be administering it less often, though, it might be less costly in the long run. 

All formulations cost $52.49 per treatment, which means you’ll be spending the same whether you have a Pomeranian or a Labrador. Each treatment dose will last for 3 months before you need to buy it again. That would amount to $209.96 for a year.

For a little over 200 dollars, you can keep your dog free from ticks and fleas for a year, and that’s more than worth it. Bravecto has been proven to kill more than 98% of fleas and 100% of ticks within 12 hours of the dose. It can get the infestation controlled quickly, preventing it from spreading to other pets.

Interaction with Other Drugs

There are currently no known contraindications established for Bravecto and many dog owners can attest to its safety. Still, you need to let your vet know if you are giving your dog other medicines or supplements if you plan to use the product.

If you are using other similar products on your dog, you might need to stop administering them, or risk more complications and side effects. 

What Are the Ingredients of Bravecto?

Bravecto’s active ingredient is fluralaner, which has been proven to kill juvenile and adult fleas and ticks that include the Lone Star, American dog, brown dog, and black-legged ticks. 

Fluralaner has been proven safe for dogs that are 6 months and older weighing 4.4 pounds or more. It has undergone a lot of testing and is certified by the FDA. It can even be administered to lactating, pregnant, or breeding dogs. 

After ingestion, fluralaner is distributed via the bloodstream, so when ticks or fleas bite your dog, they are exposed to it and die. Fluralaner can start killing these parasites in as fast as 3 hours, but killing all of them may take some time, especially if there’s already a widespread infestation.


There are different approaches you can take in controlling or stopping a tick or flea infestation. Bravecto might be very effective and long-lasting but carries a list of side effects including rare instances of seizure. If you want a more natural treatment, CBD oils show promise.
