This is a specific conversation about Flea and tick prevention — what works — ask about yours and get one honest answer for your exact situation.

A Cocker Spaniel with ongoing ear infections needs a bit of care here — spot-on treatments applied to the back of the neck can migrate, and wet or inflamed ear canals can complicate things further if you're using any product that gets near the head. The most effective prevention really does depend on size, local tick risk, and treatment type, and some popular products are notably weaker than others. To point you to the right option: is your dog a standard or working Cocker, roughly what do they weigh, and are you in an area with significant tick exposure — woodland walks, long grass, that sort of thing?
She's a standard Cocker, about 10kg. We're in the Surrey Hills so yes, ticks are definitely a problem. She gets walked in woodland most days.

Got it — 10kg, high tick pressure, and ear infections to work around. Before I give you a firm recommendation, one quick question: is she currently on any medication for the ear infections, particularly any systemic antibiotics or antifungals? And has your vet flagged any sensitivities or reactions to flea treatments in the past?
She's on ear drops at the moment, nothing systemic. No known reactions to flea treatments, we've just been using Frontline which I suspect isn't doing much.
inparticular.ai
Your suspicion is right — Frontline (fipronil) has well-documented resistance issues in the UK now, and for a dog doing daily woodland walks in Surrey it's genuinely not adequate for tick control. Given her ear situation, I'd steer you away from spot-ons entirely. The cleaner solution here is NexGard chewable tablets. It's a monthly oral chew containing afoxolaner — highly effective against both fleas and ticks including the main UK species, no topical application near the head or neck, and no interaction risk with ear drops. At 10kg she'd be in the small-to-medium dose band. It does require a prescription in the UK, so you'd need a quick vet conversation, but most vets will prescribe it readily and it's widely available online once you have one.
That sounds much more sensible. Is it safe to use while she's being treated for the ear infection?
inparticular.ai
Yes — because NexGard is systemic and the ear drops are topical, they work in completely separate compartments and there's no known interaction. The one thing worth mentioning to your vet when you ask for the prescription is that she has active ear disease, just so they can note it — but it won't change the recommendation. NexGard is actually one of the treatments vets reach for when they want reliable tick cover without the mess or migration risk of spot-ons. For a dog doing your kind of walks, it's the right call.
Great, I'll ask at our next appointment. Is there anything else I should be doing alongside it?
inparticular.ai
Two things worth adding: first, do a tick check after every woodland walk regardless — NexGard kills ticks after attachment rather than repelling them, so finding and removing them quickly still matters for reducing disease transmission risk. A fine-toothed tick hook kept by the door is useful. Second, Cocker Spaniels with ear infections can sometimes have an underlying allergy, and flea allergy dermatitis can drive ear inflammation — so if the ear infections are chronic and recurrent, it's worth asking your vet whether a flea allergy component could be involved. Consistent monthly NexGard cover will rule that out as a factor, which is useful diagnostic information in itself.
