Flea prevention for Bichon Frise puppy

Moving into a carpeted home with a young puppy is actually the perfect moment to get flea prevention sorted before any problem starts — carpets are exactly where flea eggs, larvae, and pupae like to hide, and once they're established they're a real pain to shift. Worth knowing: 95% of a flea infestation lives in the environment, not on the dog, so treating both the pet and the home matters from day one. Before I point you toward anything specific, a couple of quick questions — how old is your Bichon Frise exactly, and is the carpeted house a completely new build or has it had pets living in it before?

That's really useful to know — a house that had a dog in it recently is a genuine risk, even if it looks clean. Flea pupae can lie dormant in carpet fibres for months and hatch when they sense warmth and vibration, so your puppy moving in could actually trigger a hatch. At 4 months and Bichon Frise size, she'll be under 4kg, which is the key weight threshold for most products. Is she currently on any flea or worming treatment from the breeder or vet?

Right, so she's unprotected and moving into a potentially risky environment — let's fix that quickly. For a 4-month-old Bichon Frise under 4kg, I'd go with Advantage 40 spot-on for small dogs and puppies. It's licensed from 8 weeks, works on contact so fleas don't need to bite, and is very well tolerated by small breeds. It won't cover ticks, but at this stage flea prevention is your immediate priority and Advantage is about as gentle and reliable as it gets for a puppy this age. Apply it to the back of the neck, keep her dry for 48 hours, and reapply monthly. For the house itself — given the previous dog — I'd strongly suggest a household flea spray like Indorex at the same time. One can covers the whole house and protects for up to 12 months.

Yes, Advantage is available over the counter — no prescription needed, you can order it directly from Amazon UK or pick it up at a pet shop. For the house spray, do it before you move furniture in if you can, or at the very minimum before your puppy spends her first night there. Spray all the carpets, along skirting boards, under furniture edges, and any soft furnishings. Let it dry fully before she goes in — usually a couple of hours with good ventilation. Doing both on the same day is ideal: spray the house, let it air, apply Advantage to your puppy, job done.

You can apply Advantage now and book the vet for whenever suits — the two don't conflict. At her first appointment your vet will likely recommend moving to a prescription product like Bravecto or NexGard Spectra as she gets older, since those also cover ticks and lungworm. But for right now, Advantage does exactly what you need. You're in good shape — catching this before the infestation starts rather than after is the right call.
