Canine Lyme disease cases are surging across the UK countryside this spring, with veterinarians reporting alarming numbers as tick season intensifies. According to a 2025 survey by the British Veterinary Association (BVA), April and May represent peak transmission months, yet many dog owners remain unaware of the risks lurking in their local parks and woodland walks. In this article you’ll discover the warning signs your dog might have Lyme disease, which regions are most affected, and the one preventative step vets wish every owner would take before April ends.
📊 Key Figures 2025
- 63% rise in confirmed Lyme cases: UK veterinary practices documented a 63% increase in canine Lyme disease diagnoses between March and May 2024 compared to the same period in 2023, according to the BVA’s Spring Health Report 2025.
- 1 in 8 ticks carries Borrelia burgdorferi: Research from the Royal Veterinary College (RVC) found that approximately 1 in 8 ticks tested in UK woodlands carry the bacterium responsible for Lyme disease.
- Dogs over 7 years at higher risk: 73% of confirmed Lyme cases involved dogs aged seven years or older, making senior pets particularly vulnerable.

Why April Is Peak Tick Season
Spring warmth triggers an explosion in tick populations across British countryside. As temperatures climb above 7°C consistently, ticks emerge from dormancy and actively seek hosts—your dog being the perfect target.
The South West, Lake District, Scottish Highlands, and parts of the Midlands have reported the highest concentrations. However, ticks are spreading further north and into suburban parks, meaning no region is entirely safe.
Early Warning Signs Your Dog Might Have Lyme Disease
Many owners mistake early Lyme symptoms for general tiredness. Your dog may develop a circular red rash (erythema migrans) at the bite site, though this is often hidden by fur.
Key behavioural changes include lethargy, lameness in one or more legs (often shifting between limbs), reluctance to jump or play, fever, and joint swelling. Some dogs show no symptoms for weeks or months, making tick prevention absolutely critical.
Max, a 9-year-old Labrador from the Cotswolds, went undiagnosed for three weeks with subtle lameness before his owner noticed him favouring his front right leg consistently. A blood test at Gloucestershire Veterinary Referral Centre confirmed Lyme disease, and early antibiotic treatment prevented serious complications.
✅ Expert Tip
Tick checks within 24 hours of a woodland walk are essential. Part your dog’s coat systematically, checking warm areas: ears, groin, armpits, and between toes. Proper removal matters—use fine-tipped tweezers or a tick-removal tool (never crush the tick, as this releases bacteria). Your vet can recommend prescription tick preventatives like spot-on treatments or tablets that offer month-long protection.
Prevention: The One Step That Changes Everything
Vaccination against Lyme disease is not currently available in the UK, unlike in the US. This means prevention relies entirely on tick control and early detection.
The PDSA and BVA both recommend starting prescription tick treatments before April if your dog frequents countryside areas. Over-the-counter products vary in effectiveness; your vet can advise on prescription options with superior efficacy against Ixodes ricinus (the principal UK tick species).
Permethrin-based collars, monthly spot-on treatments, and oral medications are all viable. Whichever you choose, consistency is non-negotiable—one missed month during tick season significantly elevates risk.
⚠️ Warning
If your dog shows lethargy, lameness, fever, or loss of appetite following a woodland walk, contact your vet within 48 hours. Don’t wait for a rash to appear. Lyme disease is treatable with antibiotics if caught early, but untreated cases can lead to chronic joint pain, kidney damage, and neurological complications.
What Vets Are Seeing This Year
Veterinary surgeries across the UK report unprecedented demand for Lyme testing in spring. Cases are no longer concentrated in rural areas; suburban parks in London, Manchester, and Edinburgh have documented infected ticks.
Climate change is expanding tick habitats northward and extending transmission seasons. What was once a problem for rural dog owners is now a concern for urban pet parents too.
The Bottom Line
April 2025 marks another critical window for Lyme disease prevention. The surge in cases, confirmed by the BVA’s latest data, underscores why tick control cannot be delayed. A single missed preventative dose during spring could mean the difference between a healthy dog and months of antibiotic treatment and chronic pain.
Have you started tick prevention for spring yet? Your countryside walks don’t have to pause—but they do need protection. Speak to your vet about prescription tick treatments this week, and make post-walk tick checks a non-negotiable habit through May.
