Bravecto Chew for Dogs: Dosage, Cost, and How to Give It
If you have ever tried to get a chew into a reluctant dog, you already know the label is only half the job. The US label for Bravecto Chew sets one dose every 12 weeks, given by mouth with food, according to DailyMed (US National Library of Medicine label), and the rest of this piece checks those rules against regulator text, then follows the prices as far as the evidence goes.
Active ingredient: Fluralaner · Labeled use: Flea and tick infestations in dogs · Dosing interval: Every 12 weeks, with food · Protection period: Up to 12 weeks
Quick snapshot
- Fluralaner, labeled for flea and tick infestations in dogs, given once every 12 weeks (DailyMed (US National Library of Medicine label))
- No onset-of-action time and no euro price for Ireland appear in the supplied sources; the listed prices are in pounds sterling (FarmVetSupplies (UK veterinary retailer))
- Lone star ticks call for an 8-week interval, per the manufacturer’s US site (Bravecto US (manufacturer, Merck Animal Health))
- UK retail status is prescription-only (POM-V), so Irish licensing and prescription rules are the next check (AniMed (UK veterinary pharmacy))
The label facts agree on the dosing schedule and split on who can receive the chew.

How soon does BRAVECTO Chew work?
What the label says about protection timing
- The labeled protection period is 12 weeks against fleas and certain ticks, according to DailyMed (US National Library of Medicine label).
- No onset-of-action time appears in any supplied source, so no speed-of-action figure can be printed with confidence.
Why protection is described in weeks
- The label counts the interval in weeks, not days, so the schedule works best as a dated reminder on the calendar.
- Chewy’s product FAQ reports that safety studies at up to 5X the recommended dose, given at 8-week intervals for three treatments, showed no expected adverse effects from an accidental second dose within 12 weeks (Chewy (US online pet pharmacy product FAQ)).
The safety figure comes from a retailer’s product page, not a regulator, so the label’s own dosing interval should set the schedule.
The implication: the 12-week interval is the protection story, and the sources supply no speed-of-action number to fill the gap.
Where can I buy Bravecto for my dog?
Prescription status varies by country and must be checked
- In the UK, AniMed (UK veterinary pharmacy) lists Bravecto chewable tablets as prescription-only (POM-V).
- The supplied evidence does not verify prescription status for an Irish-licensed product.
A retailer listing shows where a product is sold, not whether a vet has to approve it in your country.
Retail listings versus veterinary supply
- AniMed (UK veterinary pharmacy) states that regulations prevent sending veterinary medicines to Northern Ireland, which rules out one mail-order route for buyers there.
- US online pharmacies list prices in dollars only, so their pages do not show what an Irish buyer would pay.
A product page that shows a price does not prove that a vet will dispense the chew without a prescription in your country.
The implication: for an Irish owner, the purchase route runs through a prescription first, and the price comes second.
How much does a 3 month supply of Bravecto cost?
How much do vets charge for Bravecto?
- UK: FarmVetSupplies (UK veterinary retailer) lists Bravecto chewable tablets from £17.20 for the 112.5 mg toy-dog strength to £25.75 for the 1400 mg extra-large strength, inc VAT, prescription required.
- US: according to Chewy (US online pet pharmacy), the 12-week chew costs $79.99 to $84.99 across the weight bands.
- US: according to 1800PetMeds (US online pharmacy), the 4.4–9.9 lb chew lists at $79.99, and a 22–44 lb two-chew package lists at $167.98.
- A 12-week dose is one chew, so the per-chew price is the closest match to a three-month supply.
Irish prices are not in the sources
- FarmVetSupplies (UK, ROI and NI veterinary retailer) describes its service as covering the UK, the Republic of Ireland and Northern Ireland, yet its listed prices are in pounds sterling.
- No euro price for an Irish retailer or clinic appears in the evidence used for this article.
A US dollar price and a UK pound price measure different markets and different weight bands, so neither one predicts what an Irish owner will pay.
The trade-off: the cheapest listed chew is not always the one a vet will sell you, so the price check and the prescription check belong together.
How to get a dog to take a Bravecto pill?
What the label says about giving it with food
- The UK SPC says to give the chew at or around feeding time, and if the tablet is not taken voluntarily it can be given with food or directly into the mouth, according to UK Veterinary Medicines Directorate (product characteristics).
Giving the chew with a meal is the label’s rule, not an owner’s trick, so the steps below start there.
- Offer the chew at mealtime, close to the dog’s usual feeding time.
- If the dog will not take the chew voluntarily, the SPC allows giving it with food or placing it directly into the mouth.
- Watch the dog swallow the chew before you leave the room.
- Never break the chew to make the dose fit a smaller dog.
Can I cut Bravecto in half for a small dog?
- No. Strength is set by weight band, and the UK SPC warns that underdosing can result in ineffective use and favor resistance development, according to UK Veterinary Medicines Directorate (product characteristics).
What to do if a dog won’t eat Bravecto
The supplied sources address refusal only through the SPC’s options of giving the chew with food or directly into the mouth. A dog that refuses repeatedly needs a vet’s advice before any other approach.
The implication: an owner who splits, crushes, or skips the meal is working outside the label, and the underdosing warning is the reason it matters.
What are the downsides of Bravecto?
Which adverse reactions the label lists
- The most commonly reported adverse reactions are vomiting, lethargy, diarrhea, anorexia and pruritus, according to Bravecto US (manufacturer, Merck Animal Health).
- The UK and US labels set different minimum ages and weights, so the rule that applies depends on which licensed product your country uses.
Limits of the evidence
- No clinical trial or peer-reviewed efficacy study appears in the supplied evidence, so efficacy claims rest on label and manufacturer text.
- Adverse reaction frequencies are not given in any supplied source, so the list above carries no rates.
A chew that goes down at mealtime is simple to hand over, but the same rules leave little room for splitting, skipping, or swapping strengths.
The implication: the sharper downside is dosing discipline, because the SPC attaches a stated consequence to underdosing while the supplied sources attach no rates to the common adverse reactions.
Weight bands, one pattern: the strength rises with body weight in both systems, and the two systems draw their lines at slightly different points.
| US weight band | US chew strength | UK weight band | UK tablet strength |
|---|---|---|---|
| 4.4–9.9 lb | 112.5 mg | 2–4.5 kg | 112.5 mg |
| >9.9–22.0 lb | 250 mg | >4.5–10 kg | 250 mg |
| >22.0–44.0 lb | 500 mg | >10–20 kg | 500 mg |
| >44.0–88.0 lb | 1000 mg | >20–40 kg | 1000 mg |
| >88.0–123.0 lb | 1400 mg | >40–56 kg | 1400 mg |
| Over 123.0 lb | Combination of chews | Over 56 kg | Combination of two tablets |
Upsides
- Labeled dosing is a single chew, not a daily routine.
- Strength follows body weight, so the dog’s size sets the chew.
- Labeled for both flea and tick control in dogs.
Downsides
- Both labels call for giving it with food or at feeding time.
- The UK SPC rules out breaking or dividing the chew, and the supplied text gives no support for crushing.
- UK retail requires a prescription, which adds a vet step.
Confirmed facts
- Active ingredient: fluralaner, per DailyMed (US National Library of Medicine label).
- Dosing interval: every 12 weeks, by mouth with food, per DailyMed (US National Library of Medicine label).
- Strengths: five, from 112.5 mg to 1400 mg, per DailyMed (US National Library of Medicine label).
What’s unclear
- Onset-of-action time.
- Prescription status for an Irish-licensed product.
- Current prices in euro, including Ireland.
- Whether a chew exists for cats; the supplied sources cover dogs only.
- Adverse reaction frequencies.
“The chewable tablets should not be broken or divided.”
UK Veterinary Medicines Directorate (product characteristics)
“Bravecto has not been shown to be effective for 12-weeks duration in puppies less than 6 months of age.”
Bravecto US (manufacturer, Merck Animal Health)
The biggest gap is money: none of the supplied sources gives an Irish euro price, so the cost question stays open until an Irish vet or retailer publishes one. For Irish dog owners, the choice is clear: confirm the licensed product and prescription route with a vet before comparing prices, or treat any US or UK price as a rough guide only.
