Bravecto Chews is the first oral chew for dogs to provide up to 12 weeks of protection against fleas and ticks. One chew provides broad-spectrum and long-lasting protection that starts to kill fleas within 2 hours and controls 4 tick species: black-legged tick (a.k.a. deer tick), American dog tick, brown dog tick, and lone star tick. Bravecto Chews eliminates current flea infestations and prevents new ones from developing for 12 weeks. With one chew, Bravecto Chews is easier to give and less to worry about for you! Bravecto Chews requires a prescription from your veterinarian.

Key Benefits

  • With one dose, Bravecto Chews resets the clock on flea and tick protection by providing effective prevention and treatment for both fleas and ticks for up to 12 weeks.
  • Close to a full year of protection with only 4 doses. No more monthly dosing!
  • No potential for messy application issues and no need to isolate from children or other pets after treatment
  • Fewer doses mean fewer chances to miss a dose decreasing the likelihood of having gaps in protection
  • Dogs love the taste!

How It Works

After giving your dog Bravecto Chews, the medication quickly reaches tissue fluids under your dog's skin. When fleas and ticks feed on your dog, they ingest Bravecto and die. Bravecto Chews kills fleas, prevents flea infestations and kills ticks (black-legged tick (a.k.a. deer tick), American dog tick, and brown dog tick) for 12 weeks. Bravecto Chews also kills lone star ticks for 8 weeks.


Bravecto kills adult fleas and is indicated for the treatment and prevention of flea infestations (Ctenocephalides felis) and the treatment and control of tick infestations [Ixodes scapularis (blacklegged tick), Dermacentor variabilis (American dog tick), and Rhipicephalus sanguineus (brown dog tick)] for 12 weeks in dogs and puppies 6 months of age and older, and weighing 4.4 pounds or greater.

Bravecto is also indicated for the treatment and control of Amblyomma americanum (lone star tick) infestations for 8 weeks in dogs and puppies 6 months of age and older, and weighing 4.4 pounds or greater.

Bravecto should be administered orally as a single dose every 12 weeks according to the Dosage Schedulebelow to provide a minimum dose of 11.4 mg/lb (25 mg/kg) body weight.

Bravecto may be administered every 8 weeks in case of potential exposure to Amblyomma americanum ticks (see Effectiveness).

Bravecto should be administered with food.

The potential risks ticks pose to pets can be stressful to pet owners wanting to ensure their pet receives effective coverage. Bravecto kills 4 different species of ticks commonly found on dogs and 2 species found on cats to protect your pet for 12 weeks.*5-7



There are no known contraindications for the use of the product.


Not for human use. Keep this and all drugs out of the reach of children. Keep the product in the original packaging until use, in order to prevent children from getting direct access to the product.

Do not eat, drink or smoke while handling the product. Wash hands thoroughly with soap and water immediately after use of the product.


Bravecto has not been shown to be effective for 12-weeks duration in puppies less than 6 months of age. Bravecto is not effective against Amblyomma americanum ticks beyond 8 weeks after dosing (see Effectiveness).

Adverse Reactions:

In a well-controlled U.S. field study, which included 294 dogs (224 dogs were administered Bravecto every 12 weeks and 70 dogs were administered an oral active control every 4 weeks and were provided with a tick collar); there were no serious adverse reactions. All potential adverse reactions were recorded in dogs treated with Bravecto over a 182-day period and in dogs treated with the active control over an 84-day period. The most frequently reported adverse reaction in dogs in the Bravecto and active control groups was vomiting.

Percentage of Dogs with Adverse Reactions in the Field Study
Adverse Reaction (AR) Bravecto Group: Percentage of Dogs with the AR During the 182-Day Study (n=224 dogs) Active Control Group: Percentage of Dogs with the AR During the 84-Day Study (n=70 dogs)
Vomiting 7.1 14.3
Decreased Appetite 6.7 0.0
Diarrhea 4.9 2.9
Lethargy 5.4 7.1
Polydipsia 1.8 4.3
Flatulence 1.3 0.0

In a well-controlled laboratory dose confirmation study, one dog developed edema and hyperemia of the upper lips within one hour of receiving Bravecto. The edema improved progressively through the day and had resolved without medical intervention by the next morning.

Clinical Pharmacology:

Peak fluralaner concentrations are achieved between 2 hours and 3 days following oral administration, and the elimination half-life ranges between 9.3 to 16.2 days. Quantifiable drug concentrations can be measured (lower than necessary for effectiveness) through 112 days. Due to reduced drug bioavailability in the fasted state, fluralaner should be administered with food.

Mode of Action:

Fluralaner is for systemic use and belongs to the class of isoxazoline-substituted benzamide derivatives. Fluralaner is an inhibitor of the arthropod nervous system. The mode of action of fluralaner is the antagonism of the ligand-gated chloride channels (gamma-aminobutyric acid (GABA)-receptor and glutamate-receptor).


Bravecto began to kill fleas within two hours after administration in a well-controlled laboratory study. In a European laboratory study, Bravecto killed fleas and Ixodes ricinus ticks and reduced the numbers of live fleas and Ixodes ricinus ticks on dogs by >98% within 12 hours for 12 weeks. In a well-controlled laboratory study, Bravecto demonstrated 100% effectiveness against adult fleas 48 hours post-infestation for 12 weeks. In well-controlled laboratory studies, Bravecto demonstrated ≥93% effectiveness against Dermacentor variabilis, Ixodes scapularis and Rhipicephalus sanguineus ticks 48 hours post-infestation for 12 weeks. Bravecto demonstrated ≥90% effectiveness against Amblyomma americanum 72 hours post-infestation for 8 weeks, but failed to demonstrate ≥90% effectiveness beyond 8 weeks.

In a well-controlled U.S. field study, a single dose of Bravecto reduced fleas by ≥99.7% for 12 weeks. Dogs with signs of flea allergy dermatitis showed improvement in erythema, alopecia, papules, scales, crusts, and excoriation as a direct result of eliminating flea infestations.

Palatability: In a well-controlled U.S. field study, which included 559 doses administered to 224 dogs, 80.7% of dogs voluntarily consumed Bravecto within 5 minutes, an additional 12.5% voluntarily consumed Bravecto within 5 minutes when offered with food, and 6.8% refused the dose or required forced administration.

Animal Safety:

Margin of Safety Study: In a margin of safety study, Bravecto was administered orally to 8 - to 9-week-old puppies at 1, 3, and 5X the maximum label dose of 56 mg/kg at three, 8-week intervals. The dogs in the control group (0X) were untreated.

There were no clinically-relevant, treatment-related effects on physical examinations, body weights, food consumption, clinical pathology (hematology, clinical chemistries, coagulation tests, and urinalysis), gross pathology, histopathology, or organ weights. Diarrhea, mucoid and bloody feces were the most common observations in this study, occurring at a similar incidence in the treated and control groups. Five of the twelve treated dogs that experienced one or more of these signs did so within 6 hours of the first dosing. One dog in the 3X treatment group was observed to be dull, inappetant, with evidence of bloody diarrhea, vomiting, and weight loss beginning five days after the first treatment. One dog in the 1X treatment group vomited food 4 hours following the first treatment.

Reproductive Safety Study: Bravecto was administered orally to intact, reproductively-sound male and female Beagles at a dose of up to 168 mg/kg (equivalent to 3X the maximum label dose) on three to four occasions at 8-week intervals. The dogs in the control group (0X) were untreated.

There were no clinically-relevant, treatment-related effects on the body weights, food consumption, reproductive performance, semen analysis, litter data, gross necropsy (adult dogs) or histopathology findings (adult dogs and puppies). One adult treated dog suffered a seizure during the course of the study (46 days after the second treatment). Abnormal salivation was observed on 17 occasions: in six treated dogs (11 occasions) after dosing and four control dogs (6 occasions).

The following abnormalities were noted in 7 pups from 2 of the 10 dams in only the treated group during gross necropsy examination: limb deformity (4 pups), enlarged heart (2 pups), enlarged spleen (3 pups), and cleft palate (2 pups). During veterinary examination at Week 7, two pups from the control group had inguinal testicles, and two and four pups from the treated group had inguinal and cryptorchid testicles, respectively. No undescended testicles were observed at the time of necropsy (days 50 to 71).

In a well-controlled field study Bravecto was used concurrently with other medications, such as vaccines, anthelmintics, antibiotics, and steroids. No adverse reactions were observed from the concurrent use of Bravecto with other medications.

After you give your pet Bravecto, it quickly reaches tissue fluids just under your dog's or cat's skin. When fleas and ticks feed, they ingest Bravecto and die.

Bravecto Chew starts killing fleas (Ctenocephalides felis) within 2 hours, and kills ticks (Ixodes ricinus) within 12 hours.*1 Bravecto Chew kills fleas, prevents flea infestations, and kills ticks (black-legged tick, American dog tick, and brown dog tick) for 12 weeks. Bravecto Chew also kills lone star ticks for 8 weeks.1

There are no problems reported in field trials in dogs and cats that received Bravecto alongside other commonly used medicines.1-3, 12 However, your veterinarian is your pet's healthcare expert, so it is always best to discuss all of your pet's treatments with them, whether prescription or over-the-counter supplements.
In a US field study where dogs were treated at home, over 93% of dogs ate the chew voluntarily-either by itself or with food.1
Bravecto Chew should be given with food. If a chew is broken or crumbles, make sure your dog still receives the whole dose.
No. Even immediate bathing, shampooing, or swimming won't affect how well Bravecto Chew works because it's not a topical treatment. Coat length and grooming or brushing also have no impact on how well it works.
Yes. Bravecto is approved for use in breeding, pregnant, and lactating dogs.1,4
In a well-controlled laboratory study, Bravecto was shown to be safe in collies known to be MDR-1 gene deficient. Collies with the defect were administered 3 times the deliverable dose and had no adverse events.11
It is always best to discuss your pet's medical treatment with your veterinarian. However, Bravecto has a high margin of safety. In safety studies, Bravecto was tested in healthy dogs and puppies at up to 5 times the recommended dose at 8-week intervals for 3 treatments.1 Therefore, no adverse effects are expected if dogs are inadvertently treated twice with the recommended dose within 12 weeks, but please contact your veterinarian.

If vomiting occurs, check with your vet to decide whether to redose or not; however, if an otherwise healthy dog vomits within 3 hours of receiving Bravecto , it is recommended that the dog be redosed. To help ensure that the dog does not vomit again, it is suggested to wait 24 hours until redosing.

If 4 or more hours have passed before the vomiting occurs, it is likely that the medication has been absorbed and the dog is protected. If the vomiting repeats again, DO NOT give a third chew, and call your veterinarian.

If you suspect that a side effect has taken place as a result of giving the dog Bravecto, please report it to Merck Technical Services at 1-800-224-5318, and follow any advice that they provide.1

April 26, 2021
My dog tolerates these well, I have no issues with the product.

This was my first order from this company, and there was a little snafu in them trying to contact my vet for the prescription. I appreciate Kent calling and letting me know of the delay, however I ended up having to contact my vet and facilitate the prescription verification, whereas I didn't need to when I used other pet med websites. Hopefully it was a one-time issue due to being a new customer, and since the price is better here so I will continue to order from them.

This is the only product I've found that will control fleas and ticks on all 7 of my dogs on a horse ranch in rural Oklahoma. None of my dogs have experienced any side effects. Love the product, but it is expensive. Even though it works for 3 months, it costs me $100 per dog to get through the summer. I still spend the money because it works.

March 27, 2021
Bravecto has been working fine for my last sheltie and my current sheltie,,,,,with no side effects at all. They don't like the taste and I do have to hide pieces in food, but it works very well, never have fleas or ticks on them, even though the common areas in my apt complex do have fleas.
ProsBeside working so well with no side effects, the price is also very good
ConsI have had issues getting the product on time, and once it didn't arrive at all,,,,but things were straightened out and another was shipped to me at no cost.

Bravecto for dogs 44 to 88 lbs.
March 18, 2021
Works great. Much better than topicals I have used. My Brittany dog goes out in woods and fields and does a lot of swimming. There is no waiting for him to be able to swim or bathe after giving as with the topicals I have used and I haven't found any ticks on him even in the height of tick season. No fleas either. Easy to use, lasts 3 months, great value from Entirely Pets.

Merchant Response:Brittany is beautiful! Thanks for shaing.
ProsEasy to use, lasts for 3 months.
ConsMy Brittany is right on the cusp of the weight limit after Covid this last year so I opted for the next higher dose to ensure he was covered. I'd like the weight limits to be more spread out.

Works Great But Dog Doesn’t Like Taste
March 7, 2021
I really like Bravecto as I can give my dog one chew every few months and generally not have to worry about her getting ticks or fleas. Itís so much easier than a messy topical solution and much easier fir me to remember than a monthly chew. The only downside is my dog absolutely will not eat this chew unless I smother it in peanut butter. Iíve tried many different ways to entice her to eat it, but thatís the only thing that works, Still, small inconvenience.

Easy to give. Wasteful packaging. Pricey.
December 17, 2020
I like Bravecto because I only have to give it to my dogs once every three months. It is quite pricey though, especially when you have more than one dog. (Entirely Pets usually has the best price.) I also like that it's chewable. (One of my dogs has very long hair, and it's difficult putting the topical medication on her without some of it ending up in her hair instead of on her skin.) The other negative is that the packaging is very wasteful. There's only one pill per box, which is three times the size it needs to be. Additionally, the boxes all were crushed upon arrival, even thought the padded envelopes were doubled up (also a waste of packaging).

Merchant Response:hnh, We try to keep our cost as low as possible. That is our promise to you. We are looking into why the boxes could have been squished like they were. We agree that there could easily be less but that's out of our hands. Thank you for the review. Take care!
