As our dogs age, their needs change and so do the questions we ask about their care. One common concern we hear at IndiPetShop is: “Is Bravecto safe for my senior dog?” It’s a valid worry! Senior dogs often have delicate health, and choosing the right flea/tick treatment requires extra care. Let’s break down the facts, risks, and expert advice to help you decide what’s best for your furry elder.
What is Bravecto?
Bravecto is a popular oral flea and tick treatment that protects dogs for up to 12 weeks with a single dose. Its active ingredient, fluralaner, works by targeting the nervous systems of parasites, effectively killing fleas and ticks within hours.
While it’s widely used and FDA-approved, debates about its safety—especially for older dogs—persist online. Let’s separate myths from science.
Why Senior Dogs Need Special Consideration
Aging impacts dogs in ways that matter for medication safety:
Organ function: Liver/kidney efficiency declines, affecting how drugs are processed.
Weight loss: Muscle loss in seniors can lead to overdosing if dosage isn’t adjusted.
Immune systems: Weaker defenses mean side effects (if any) may hit harder.
Is Bravecto Safe for Senior Dogs? The Facts
According to veterinary studies and manufacturer guidelines:
✅ The Good News
No Age Restrictions: Bravecto is approved for dogs over 6 months old, with no upper age limit.
Studies on Seniors: Research on fluralaner (Bravecto’s active ingredient) shows it’s well-tolerated in older dogs when dosed correctly.
Efficiency: Long-lasting protection reduces stress from frequent applications—a perk for arthritic seniors who hate being handled.
⚠️ Cautions to Consider
Pre-Existing Conditions: Dogs with severe liver/kidney disease or epilepsy may need alternatives (consult your vet).
Side Effects: While rare, some dogs experience vomiting, diarrhea, or lethargy. Senior dogs may recover slower from these.
Weight Matters: Bravecto is dosed by weight, so ensure your dog’s current weight is accurate (muscle loss can skew this).
5 Steps to Safely Use Bravecto for Older Dogs
Vet Check-Up First: Bloodwork to assess liver/kidney health is ideal.
Weight Check: Use a recent vet weigh-in (not your bathroom scale!).
Monitor Closely: Watch for itching, vomiting, or lethargy in the first 72 hours.
Hydration: Ensure your dog drinks plenty of water to aid metabolism.
Report Reactions: Contact your vet immediately if symptoms arise.
Bravecto Alternatives for Senior Dogs
If Bravecto isn’t the right fit, consider:
Frontline Plus (Topical): Non-systemic, but lasts only 30 days. LINK
Seresto Collar: Low-dose, continuous protection for 8 months. LINK
Final Verdict
Bravecto can be safe for senior dogs if:
-
They’re otherwise healthy (no severe organ issues).
-
The dose matches their current weight.
-
You monitor them post-dose.
When in doubt, ask your vet to weigh risks vs. benefits. Fleas and ticks pose serious threats to older dogs (anemia, infections), so protection is still crucial.
