This is a specific conversation about Flea treatment for dogs — getting on top of it fast — ask about yours and get one honest answer for your exact situation.

Moving from a prescription flea treatment to an over-the-counter option is a smart thing to plan carefully — the gap in protection matters, and not all OTC products are equal. Before I point you to something specific, just worth mentioning: effective flea control means treating both your dog and your home. Around 95% of fleas live in carpets, bedding, and soft furnishings, not on the animal itself, so even a great spot-on won't solve things alone. Can you tell me roughly how heavy your Border Collie is, whether you're currently seeing any fleas on him or in the house, and what your vet had you using before?
He's about 22kg. We were on Bravecto for the past year — vet said he's healthy and we don't need the prescription strength anymore as we've got things under control. No live fleas at the moment, just want to keep it that way. We do treat the house with a spray every few months too.

That's a solid position to be switching from — Bravecto is effective and you've clearly been on top of it. At 22kg your Collie sits comfortably in the large dog range. The main thing to know is that Bravecto is a fluralaner oral treatment lasting 12 weeks, so timing your first OTC application to land before that window closes is important — you don't want even a week's gap. What did your vet suggest as a rough timeline for making the switch?
They said to apply the new treatment about a week before the Bravecto dose would have been due. So I've got around three weeks. They didn't recommend a specific product, just said something topical would be fine.

Good — three weeks gives you plenty of time to get set up. For a healthy adult Border Collie with no active infestation, I'd go with Frontline Plus for Large Dogs. It contains fipronil and S-methoprene, which kills adult fleas and also targets flea eggs and larvae — that second ingredient is what separates it from basic Frontline and makes it genuinely worth using for ongoing prevention rather than just reaction. It's widely available, well-tolerated in Collies, and a single pipette covers dogs 20–40kg, so the dose is right for him. Apply it to the back of the neck where he can't lick it, part the fur down to skin level, and let it dry for 24 hours before any bathing. One thing to keep doing: that home spray every three months is exactly right — pair it with Frontline Plus and you've got both fronts covered.
Is Frontline Plus as strong as Bravecto though? I don't want to feel like we're going backwards.

It's a fair question. Bravecto works systemically — it's in the bloodstream, so a flea has to bite to be affected. Frontline Plus works on contact through the coat and skin oils, so it can kill fleas before they bite. Neither is universally 'stronger' — they work differently. What Bravecto had over most OTC options was the 12-week duration and tick coverage. If tick exposure is a concern where you walk him, it's worth knowing Frontline Plus also covers ticks, though the reapplication is monthly rather than quarterly. For a dog that's already clear with consistent home treatment, Frontline Plus is genuinely sufficient — this is a sensible step down, not a compromise.
That makes sense. I'll go with Frontline Plus then. Should I get a multipack?
inparticular.ai
Yes — get the 6-pipette pack if you can find it, which covers six months. It's better value than buying singles and means you won't forget to reorder mid-cycle. Set a phone reminder for the same date each month. That's genuinely all you need alongside your home spray routine.
