Bravecto Chewables for Medium Dogs 22–44 lbs (10–20 kg) — one beef-flavoured chew gives your dog 12 weeks of flea and tick protection. Made by MSD Animal Health (the same company that makes Heartgard), Bravecto is the world's best-selling 12-week flea and tick chew. Approved by the FDA in the USA, Health Canada in Canada, the EMA in Europe and the APVMA in Australia. Ships USA, Canada and worldwide — no vet prescription required.

One chew. 12 weeks. Done.

Most flea and tick chews need to be given every month. Bravecto is different: a single chew protects your medium dog from fleas and ticks for a full 12 weeks. That's 4 monthly doses condensed into a single, beef-flavoured chew your dog will treat like a treat. Four chews a year is all you need for year-round protection.

Bravecto starts killing fleas within 2 hours and ticks within 12 hours. Once it's in your dog's system, it keeps killing new fleas and ticks for the entire 12-week period — so even if your dog picks up a new flea at the park, on a hike or from another animal, it dies before it can lay viable eggs.

Sized specifically for medium dogs 22–44 lbs

The Green pack of Bravecto is dosed for medium dogs in the 22–44 lbs (10–20 kg) weight band. That covers most Beagles, French Bulldogs, Cocker Spaniels, Border Terriers, Cavoodles, Miniature Australian Shepherds, Welsh Corgis and Staffordshire Bull Terriers. If your dog is between weight bands, weigh them before dosing — Bravecto must be given in the correct weight band for full 12-week efficacy.

What Bravecto Chewables protect against

Fleas (Ctenocephalides felis) — kills adult fleas within 2 hours and prevents new infestations for 12 weeks. Breaks the household flea cycle by stopping eggs being laid.
Black-legged / deer ticks (Ixodes scapularis) — full 12-week kill, critical for Lyme disease prevention in North America.
American dog ticks (Dermacentor variabilis) — 12 weeks of protection.
Brown dog ticks (Rhipicephalus sanguineus) — 12 weeks of protection.
Lone star ticks (Amblyomma americanum) — 8 weeks of protection.
Paralysis ticks (Ixodes holocyclus, Australia/NZ) — covered for the duration of the dose.

How Bravecto works

The active ingredient is fluralaner — a long-acting isoxazoline that kills fleas and ticks by targeting their nervous system. After your dog eats the chew, fluralaner is absorbed into the bloodstream and remains active for 12 weeks. When a flea or tick bites, it ingests the active and dies before it can transmit disease or lay eggs. Because it's systemic rather than topical, you can bathe your dog, let them swim and pat them straight after dosing — the active doesn't wash off.

How to give Bravecto

Give one Green chew every 12 weeks (4 chews per year for full annual cover)
Give with food or shortly after a meal — this improves absorption and ensures the full 12-week duration
The chew is beef-flavoured; most dogs eat it like a treat
If your dog refuses, it can be broken into smaller pieces or given in food
Mark the next dose date on your calendar — 12 weeks (84 days) after the previous dose

Pack options

1 Chew — 12 weeks (3 months) of protection — best for trying Bravecto for the first time

Active ingredient

Fluralaner. Each Bravecto Green chew is dosed to the 22–44 lbs (10–20 kg) weight band. Full strength details are on the manufacturer's leaflet inside the pack.

Safety and side effects

Bravecto Chewables are approved for dogs and puppies from 6 months of age and at least 4.4 lbs (2 kg). The most common side effects, when they occur at all, are mild and transient — vomiting, soft stool, reduced appetite or lethargy in the 24 hours after dosing. Tell your vet before use if your dog has a history of seizures, neurological disorders, or known sensitivity to isoxazoline products. Not recommended for cats — see the full Bravecto range for the Bravecto cat spot-on options.

What Bravecto Chewables doesn't cover

Bravecto Chewables protect against fleas and ticks only. They do not prevent heartworm and do not treat intestinal worms. For complete year-round parasite protection, pair Bravecto with:

A monthly heartworm preventative such as Heartgard Plus, NexGard Spectra or a generic ivermectin tablet
An intestinal wormer such as Neomax (the budget-priced generic) or Drontal

If you'd rather one product instead of three, NexGard Spectra and Simparica Trio are both all-in-one monthly chews covering fleas, ticks, heartworm and intestinal worms in a single dose.

Worldwide shipping — no prescription required

We ship Bravecto Chewables to the USA, Canada, UK, Europe, New Zealand and worldwide. No vet prescription needed. Fast dispatch with international tracking included on every order.

Frequently Asked Questions

Q: How long does one Bravecto chew last?

A: 12 weeks — that's 84 days, or roughly 3 months. A single chew gives your dog 12 weeks of continuous flea and tick protection. For year-round coverage you need 4 chews per year.

Q: How quickly does Bravecto start working?

A: Bravecto starts killing fleas within 2 hours of your dog eating the chew. Existing fleas are eliminated by 12 hours, and ticks are typically killed within 12 hours of attachment.

Q: Is Bravecto the right size for my dog?

A: The Green chew is dosed for dogs in the 22–44 lbs (10–20 kg) weight band. Weigh your dog before each dose to ensure you're in the right band. If your dog is between weight bands, your vet will normally recommend the next size up — never split chews to dose down, because Bravecto must be given at full dose for the 12-week duration to work.

Q: Can I give Bravecto with food?

A: Yes — it's strongly recommended. Give Bravecto with or shortly after a meal. Food significantly improves the absorption of fluralaner and is what ensures the full 12-week duration. Without food, the chew may not protect for the full 12 weeks.

Q: What if my dog vomits within 2 hours of eating Bravecto?

A: If your dog vomits within 2 hours of dosing, the active may not have been fully absorbed. Give another chew and contact your vet if vomiting continues. If your dog vomits more than 2 hours after the dose, the chew has been absorbed and no re-dose is needed.

Q: Does Bravecto prevent heartworm?

A: No. Bravecto Chewables cover fleas and ticks only. For heartworm prevention you need a separate monthly tablet such as Heartgard Plus or NexGard Spectra. Bravecto can be given alongside any heartworm preventative without issue.

Q: Does Bravecto kill intestinal worms?

A: No. For roundworm, hookworm, whipworm and tapeworm you need a separate intestinal wormer such as Neomax or Drontal. The all-in-one alternatives, if you want one product instead of two or three, are NexGard Spectra and Simparica Trio.

Q: Is Bravecto safe for puppies?

A: Bravecto Chewables are approved for puppies from 6 months of age and at least 4.4 lbs (2 kg). For younger puppies that need flea and tick cover, your vet may recommend a monthly product like NexGard (from 8 weeks) until the puppy reaches 6 months.

Q: Can my dog swim or be bathed after taking Bravecto?

A: Yes — straight away. Bravecto is a systemic oral chew, so the active is absorbed into the bloodstream and stays there. Unlike topical spot-on products, swimming, bathing and rain do not affect Bravecto's efficacy.

Q: Bravecto Chewables vs Bravecto Spot-On — which one is better for my dog?

A: Both contain fluralaner and both provide 12 weeks of flea and tick protection. The chew is best for owners whose dogs take oral medication easily; the spot-on is best for dogs that are reluctant pillers or have a sensitive stomach. Both are equally effective. Compare both options in the full Bravecto range.

Q: Can I give Bravecto to my MDR1-affected breed (Collie, Australian Shepherd, etc.)?

A: Yes — Bravecto has been tested in MDR1-affected dogs at multiple times the recommended dose and is considered safe at label dose. As with any medication for MDR1 breeds, mention your dog's MDR1 status to your vet so it's on file.

Q: How many chews do I need for the year?

A: 4 chews per year for year-round cover (one every 12 weeks). The 2-pack covers 24 weeks of protection and works out cheaper per dose than buying two singles.
