Tick Protection for Flat-Coated Retrievers

So your vet flagged inadequate tick protection at the annual wellness visit — that's actually a really useful prompt to act on, especially for a 10-year-old dog whose immune system isn't quite as resilient as it once was. The most effective prevention depends on your dog's size and weight, the local tick risk in your area, and whether you prefer a spot-on, collar, or oral treatment — and it's worth knowing that some widely sold products are significantly less effective than others. Can you tell me roughly how much your Flat-Coated Retriever weighs, whether you're in a higher-risk tick area (countryside, woodland walks, that sort of thing), and whether your vet mentioned any preference for treatment type?

That makes complete sense. Supermarket spot-ons typically use permethrin or older pyrethroids, and they're genuinely inconsistent — they repel some ticks but don't kill them reliably or fast enough to prevent disease transmission. For a 30kg dog doing regular woodland walks in Surrey, you want something with a proven kill speed. A few quick questions before I point you at the right product: does he have any history of seizures or neurological issues, and is he currently on any other medications?

Good to know — that rules out any contraindications with the isoxazoline class of treatments, which are the current gold standard. For a healthy 10-year-old at 30kg with high tick exposure, I'd recommend Bravecto Spot-On for Large Dogs (10–40kg). It uses fluralaner, kills ticks within 12 hours of attachment — well within the window needed to prevent Lyme disease transmission — and a single application lasts 12 weeks. That's a big practical advantage over monthly treatments, and it's considerably more reliable than anything you'd pick up in a supermarket. It's prescription-only in the UK, so you'll need your vet to authorise it, but given they flagged the issue at the wellness visit they'll almost certainly support the switch. You can get it dispensed via your vet or through a registered online vet pharmacy once you have the prescription.

At 10, Flat-Coated Retrievers can be more prone to certain health issues, so it's worth keeping an eye out in the first few days — mild lethargy or a slight skin reaction at the application site are the most commonly reported side effects with Bravecto, and they're generally transient. Because his bloodwork is clean and he's not on other medications, the risk is low. The main thing is to apply it to an area he can't lick — part the fur at the back of the neck — and let it dry fully before he gets wet or has contact with other pets. Given the tick pressure in the Surrey Hills, the protection benefit clearly outweighs the small risk profile here. Your vet will be able to confirm that when you request the prescription.

That's exactly the right move. Mention that it's for a 30kg dog and that you want the large dog formulation — that gets you the correct dose band. With the Surrey Hills tick season running pretty much year-round now, the 12-week coverage will mean you're not having to remember monthly applications either, which is a genuine bonus. Hope he keeps doing well.
