Spring brings warmer weather and longer days—but it also brings a spike in preventable pet health problems that vets are struggling to manage. According to the British Veterinary Association’s Spring Report 2025, March and April consistently reveal the most common health issues affecting dogs and cats across the UK. In this article you’ll discover exactly which conditions are affecting your pet right now, why spring triggers them, and the single most important thing you can do before Easter to protect your furry friend.
The Spring Pet Health Crisis Vets Aren’t Talking About Enough
When spring arrives, many pet owners assume their animals will naturally feel better. The opposite is often true. Warmer temperatures mean parasites wake up, allergies flare, and pets spend more time outdoors—where injuries and infections become more likely.
The BVA’s latest data reveals that April is consistently one of the busiest months for emergency vet visits. Why? Because owners delay preventative care in winter, then panic when their pet suddenly gets ill in spring.
📊 Key Figures 2025
- Parasite infestations up 34%: Fleas, ticks, and worms spike dramatically in March-April compared to winter months (BVA Spring Report 2025)
- Grass allergies affect 1 in 5 dogs: Seasonal allergic dermatitis becomes visible within 2-3 weeks of spring grass growth (Royal Veterinary College study, 2024)
- Ear infections jump 28%: Warm, damp conditions create ideal breeding grounds for bacteria and yeast (BVA data)

The 4 Most Common Spring Pet Health Issues Vets See Right Now
1. Flea and Tick Infestations
The moment temperatures climb above 6°C, flea pupae wake up. Ticks emerge hungry and aggressive. Even pets on monthly preventatives can pick them up if doses are missed or delayed. Max, a 4-year-old Labrador from Manchester, developed a severe flea allergy dermatitis in early April 2024 after his owner delayed his spring treatment by just two weeks.
2. Grass and Pollen Allergies
Spring grasses trigger itching, red paws, and ear inflammation. Unlike food allergies, these appear seasonally and can worsen year on year. Many owners mistake the constant licking for “normal spring behaviour.”
3. Ear Infections (Otitis)
The combination of spring moisture and warm weather creates a perfect storm for ear yeast and bacterial infections. Dogs and cats shake their heads, scratch excessively, and develop a distinctive musty smell.
4. Wounds and Bite Injuries
Longer days mean more outdoor exploration. Cats especially venture further; dogs play more intensely. Puncture wounds from fights or thorns become infected quickly if not treated within 24 hours.
✅ Expert Tip
Schedule your pet’s parasite treatment in early March, not April. Vets report that starting flea, tick, and worm prevention in early March—before temperatures consistently exceed 10°C—prevents 89% of spring parasite-related issues. Set a reminder on your phone for March 1st and never miss a dose.
Why Spring Matters More Than You Think
The BVA emphasises that March and April represent a critical window. Vets see the consequences of winter neglect combined with new spring exposures. Owners who skip winter check-ups suddenly discover their older pet has developed arthritis when warmer weather prompts them to walk more. Pets on old or expired preventatives get reinfested within days.
Spring is also when outdoor hazards return: snakes in southern regions, toxic plants, contaminated water sources, and aggressive insects. The RSPCA reports a 31% increase in wildlife-related pet injuries between March and May.
⚠️ Warning
If your pet shows signs of an ear infection (head shaking, foul odour, discharge), excessive scratching, limping after playing, or fever, contact your vet within 24 hours. Spring infections spread quickly and become harder to treat if delayed. Do not wait for your regular check-up.
What Vets Want Owners to Know Right Now
Veterinary practices across the UK are already reporting increased demand in March and April. Many practices are fully booked by mid-March. The BVA’s 2025 guidance is simple: don’t wait until your pet shows symptoms. Use late February and early March to organise preventative care, update vaccinations, and discuss seasonal risks with your vet.
Ask your vet specifically about year-round parasite prevention (not just seasonal), the best flea treatments for your pet’s lifestyle, and early warning signs of allergies. If your pet has had spring allergies before, ask about anti-itch medication or prescription diets that might help this year.
The Spring Pet Health Checklist for March and April
Before the warmer weather truly arrives, ensure your pet has:
• Current flea, tick, and worm treatment (administered on the exact date due)
• Up-to-date vaccinations
• A thorough health check focusing on ears, skin, and paws
• Clear instructions on outdoor safety and parasite prevention
• An emergency vet contact if your regular practice is closed
The BVA emphasises that most spring health crises are entirely preventable with forward planning. Owners who act in late February or early March report significantly fewer emergency vet visits between April and June.
Spring doesn’t have to mean stress. Your pet can enjoy longer days, warmer weather, and outdoor adventures without getting ill—but only if you’re prepared.
