Tick Prevention for Dogs UK: What Actually Works

Ticks aren't just a summer problem in the UK. While numbers peak in spring and early autumn, adult ticks are active whenever the temperature stays above about 4°C - which, in most of the country, means they're present throughout most of the year.

The concern isn't the tick itself. It's what some ticks carry. Lyme disease (Borrelia burgdorferi) is the most significant tick-borne disease in UK dogs, and cases have been rising steadily. Other tick-borne diseases are present in the UK but less common. The practical upshot is that tick prevention has moved from "nice to have" to "standard care" for dogs with any outdoor access. According to the PDSA PAW Mini Report 2025, while 81% of UK dog owners treat their dogs for fleas, tick prevention is less consistently maintained - leaving a significant proportion of the UK's 11.1 million dogs inadequately protected in tick-endemic areas.

Where the risk is highest

Ticks in the UK are most prevalent in:

• Woodland and the edges of forests
• Heathland and moorland (Exmoor, Dartmoor, the New Forest, the Peak District, the Scottish Highlands, and others)
• Long grass and bracken
• Coastal grassland and clifftops

Urban parks with dense vegetation can also harbour ticks, particularly if deer or other wildlife move through the area. If you're unsure about tick risk near you, the Big Tick Project (run in partnership with Bristol Vet School) maintains regional risk data.

What prevention looks like

There are three main approaches, often used in combination:

Prescription treatments are the most effective. Options include spot-on products (such as Advocate plus a tick-specific add-on, or products like Seresto collar) and oral chewables (NexGard, Bravecto, Simparica). Many combination products cover both fleas and ticks. Your vet will advise on the most appropriate product for your dog's size, weight, age, and lifestyle.

Tick-repellent collars such as Seresto release active ingredients slowly over several months and provide combined flea and tick protection. They're particularly useful for dogs who are difficult to treat with spot-ons or chewables.

Post-walk checks should be part of the routine for any dog who walks in tick-risk areas, regardless of whether they're on preventive treatment. Run your hands slowly through the coat, paying particular attention to the head, ears, neck, armpits, groin, between toes, and under the tail. Ticks can be very small (the size of a poppy seed before feeding) and are easy to miss in thick coats.

No preventive product provides 100% protection - checks remain important even when treatment is current.

Removing a tick

If you find a tick, the removal technique matters:

1. Use a tick hook or fine-tipped tweezers - not your fingers
2. Grasp the tick as close to the skin as possible
3. Pull upward with steady, even pressure - don't twist or jerk
4. Clean the area with antiseptic after removal
5. Do not crush, squeeze, burn, or apply Vaseline to the tick - these methods can cause the tick to release stomach contents into the bite site, increasing infection risk

A tick hook (often sold as a "tick twister") is the most reliable removal tool and costs around £2–3. Keep one in your dog kit.

What to log

See our Lyme disease condition guide for a full monitoring checklist if your dog is regularly exposed to ticks.

When you find and remove a tick, note:

• The date and location on the body where you found it
• Whether it appeared attached or just walking on the coat
• Roughly how engorged it was (a flat tick has likely not fed; a swollen tick has been attached for some time)
• Your dog's current tick prevention treatment and when it was last applied

Ticks need to be attached for roughly 24–48 hours to transmit Lyme disease, so a tick found early during a check is significantly lower risk than one that has been feeding for some time. That context matters if signs of illness develop later. The PDSA notes that Lyme disease signs in dogs typically appear two to five months after a tick bite - making a dated log of tick findings genuinely valuable if unexplained lameness or lethargy develops weeks later.

Signs of tick-borne illness

Lyme disease in dogs doesn't always follow a predictable pattern, but the classic presentation includes:

• Lethargy and reduced energy
• Fever (which you may notice as warmth or shivering)
• Reduced appetite
• Shifting leg lameness (the dog may appear to limp on different legs at different times)
• Swollen lymph nodes

These signs typically appear two to five months after infection, which makes connecting them to a tick bite difficult without a log. If your dog develops unexplained lameness or fever and you're in a tick-risk area, mention it to your vet - a Lyme disease test is straightforward.

What about Lyme disease in humans?

Dogs can bring ticks into the home that then bite humans. If you're in a tick-risk area, check yourself after dog walks as well as checking your dog. Human Lyme disease is notifiable in the UK - if you develop a "bullseye" rash (erythema migrans) after a tick bite, contact your GP promptly.

Frequently Asked Questions

My dog is on NexGard - do I still need to check for ticks? Yes. Oral products like NexGard work by killing ticks after attachment - they don't repel ticks before they bite. The tick needs to attach and start feeding before the product takes effect. Regular checks allow you to find and remove ticks promptly, reducing transmission risk.

Is tick risk year-round or just in summer? In the UK, ticks are active whenever temperatures stay above approximately 4°C. This means risk continues into late autumn in most of England and Wales, and year-round in milder coastal areas. Peak activity is typically March–May and August–October.

My dog has a thick coat - can I really check effectively? It takes more time and attention but it's possible. Work systematically in sections, parting the coat down to the skin. Ticks on dogs are most commonly found around the head and ears, under the collar, in the armpits and groin, and between the toes. These areas are worth double-checking.

My dog found a tick and I removed it. Do I need to go to the vet? Not immediately, unless your dog is showing signs of illness. Monitor for the next few weeks - lethargy, fever, lameness, or appetite changes warrant a vet call. Let your vet know about the tick removal at the next routine visit.

Can I use a human tick remover on my dog? A fine-tipped tweezer or tick hook works the same way regardless of the species being de-ticked. The technique is what matters - grasp close to the skin, steady upward pull, no twisting or squeezing.
