Flea treatment for 10-week-old Pomeranian

At 10 weeks old, your Pomeranian is right in that tricky window where the most effective prescription-strength treatments — NexGard, Bravecto, Seresto — are either not yet licensed for their age or require a minimum weight your pup probably hasn't hit. The good news is you do have a safe option right now. Before I point you to it, can you tell me roughly how much your puppy weighs, and are you seeing fleas already or is this purely preventative?

That's a really sensible position to be in — far easier to prevent than to treat an active infestation, especially with a cat in the house who can act as a relay. At 1.2kg and 10 weeks, the product I'd recommend is Johnsons Baby Flea Drops. They're specifically formulated for puppies from 8 weeks and very small dogs, use a gentler active ingredient (permethrin-free), and come in a spot-on format that's straightforward to apply to a tiny Pomeranian. They won't give you the same 12-week coverage you'd get from Bravecto down the line, but they're genuinely safe right now and will give you a working layer of protection while she grows into the heavier-duty options.

Every four weeks. At that interval they stay effective, and because she'll be growing quickly, it also means you're reassessing her weight regularly — which matters because dosing for small dogs is weight-sensitive. One other thing worth doing now: treat your home environment too. Fleas spend most of their life cycle off the animal, so with a cat already in the house, a household spray like Indorex or RIP Fleas will stop any eggs already in your carpets and soft furnishings from developing. That's not urgent if you're not seeing fleas, but worth doing before the warmer months.

NexGard Spectra is licensed from 8 weeks but requires a minimum weight of 2kg, so she'll likely be ready for it within the next month or two at her current growth rate. Once she hits 2kg, that's worth switching to — it covers fleas, ticks, and several internal parasites in one monthly chew, which is much more convenient and significantly more effective than the baby drops. Your vet can prescribe it, or you can get it through a licensed online vet pharmacy. For now though, the Johnsons Baby Flea Drops are the right call.

Good plan. You're in a much better position than most people who come to this having already spotted fleas. Get the drops applied now, grab Indorex for the house if you want to be thorough, and revisit NexGard Spectra once she's over 2kg — probably in a month or so. She'll be well protected.
