As a dog owner living in a tick-heavy area with trails and woods nearby, I’ve tried several flea and tick preventatives over the years to keep my adventurous pups protected. Bravecto (the oral chew) and Seresto (the collar) stand out for their longer-lasting coverage compared to monthly options.
They differ significantly in how they work, duration, application, and real-life performance. In this article, my main intent is to share my personal experiences, compare key features analytically, detail pros and cons, and help you choose the best one for your dog’s needs and your lifestyle.

My Experience With Bravecto

I first switched to Bravecto chewables about four years ago when monthly treatments became a hassle with my busy schedule.
The flavored chew goes down easy—my dogs treat it like a snack, no hiding in peanut butter needed. Protection kicks in fast; I’ve noticed fleas dying off quickly if any hitch a ride home.
During peak tick season on hikes, it handled everything well. Ticks might attach briefly but die soon after, preventing disease transmission in most cases. No live ticks engorged on my dogs.
One spring, we had a flea outbreak from a foster dog—Bravecto cleared it rapidly without extra home treatments. Baths and lake swims didn’t diminish it.
I’ve dosed every three months reliably, and my vet appreciates the compliance. Side effects? Minimal—one dog had mild tummy upset once, resolved quickly.
For forgetful owners or those wanting strong systemic kill, Bravecto simplified everything. It fits seamlessly if you’re already giving quarterly doses.
My Experience With Seresto
I tried the Seresto collar last year wanting even less frequent intervention.
Fitting was straightforward—adjust, buckle, trim excess. My dogs adapted quickly, forgetting it was there.
The repelling action impressed me most. Ticks crawled near but dropped off dead without attaching during wood walks. Fewer worries about Lyme.
It lasted full eight months, even with regular grooming and occasional swims. No odor, no residue on furniture.
In a high-tick summer, it prevented attachments better than previous orals. My older dog tolerated it fine, no irritation after proper fit.
I bought authentic from my vet to avoid fakes. Monitoring the first week showed no issues.
Seresto gave true hands-off protection. Ideal for multi-dog homes or constant outdoor exposure.
