Understanding How Long BRAVECTO Lasts in Dogs
When it comes to protecting your dog from fleas and ticks, BRAVECTO is one of the most popular and trusted options available. As a veterinarian-recommended treatment, it offers a long-lasting solution that minimizes the hassle for pet owners. But how long does BRAVECTO really last in dogs, and what should you know about its use? This article answers these questions in detail.
What is BRAVECTO?
BRAVECTO is a chewable flea and tick treatment for dogs that belongs to a class of drugs called isoxazolines. It is produced by Merck Animal Health and is available as an oral chew or topical solution. The main ingredient, fluralaner, acts quickly to kill fleas and ticks upon contact or feeding.
Duration of Effectiveness
A single dose of BRAVECTO is effective for:
- Up to 12 weeks (approximately 3 months) against fleas
- Up to 12 weeks for most tick species such as the black-legged tick (deer tick), American dog tick, and brown dog tick
- 8 weeks of protection against the lone star tick
This extended protection makes BRAVECTO a convenient choice as it reduces the frequency of treatments compared to monthly preventatives.
How It Works
After your dog ingests the BRAVECTO chew, the active ingredient fluralaner is absorbed into their bloodstream. When fleas or ticks feed on your pet, they ingest the chemical, which disrupts their nervous system, causing paralysis and death. Protection begins within hours:
- Fleas are killed within 2 hours of administration
- Ticks start dying within 12 hours of attachment
Benefits of BRAVECTO
- Extended protection — fewer treatments per year
- Effective against multiple tick species
- Quick action against current infestations
- Available in both oral and topical forms
- Convenient dosing schedule — only once every 12 weeks
When to Administer BRAVECTO
It's essential to follow your vet’s advice regarding the start time, especially if your location has a year-round flea and tick risk. Generally:
- Begin treatment before peak flea/tick season (early spring)
- Re-dose after 12 weeks to maintain protection
- Monitor for exposure if you delay or miss a dose
Considerations and Safety
BRAVECTO is considered safe for:
- Dogs over 6 months old and weighing more than 4.4 lbs
- Pregnant and nursing dogs (consult your vet)
However, some dogs may experience mild side effects such as:
- Vomiting
- Diarrhea
- Lethargy
- Loss of appetite
As with any medication, discuss potential risks with your veterinarian, especially if your pet has a history of seizures or other neurological issues.
Comparing BRAVECTO with Other Treatments
Here’s how BRAVECTO compares to some other flea and tick treatments:
- Monthly chews or topicals: Require 12 doses per year vs. BRAVECTO’s 4
- Collars: May last longer but vary in effectiveness and require continuous wear
- Sprays/Shampoos: Shorter duration of protection and higher maintenance
Conclusion: Is BRAVECTO Right for Your Dog?
With up to 12 weeks of flea and tick protection per dose, BRAVECTO offers convenience, efficacy, and peace of mind for dog owners. It significantly reduces the worry of monthly treatments and ensures your dog stays protected throughout the seasons. Be sure to consult your vet to determine if this treatment is right for your pet, and keep track of dosing on a calendar to maintain consistent protection.
