April Pet Health Tips: Prevent Heartworms and Lyme Disease Early

2026-04-01

Spring is finally here, and with it comes longer walks, more time outdoors, and plenty of fresh air for you and your pet. But April also marks the return of two tiny threats that can cause serious harm: mosquitoes and ticks. These pests are more than just a nuisance. They carry diseases like heartworms and Lyme disease that can impact your pet’s long-term health.

The good news is that early prevention makes a big difference. Starting now can help your pet stay protected all season long.

Tip #1: Spring Brings Mosquitoes. Year-Round Prevention Brings Peace of Mind

Heartworms are mosquito-borne; one bite is all it takes to put your pet’s health at risk. Once inside the body, heartworms grow and live in the heart and lungs, leading to serious complications over time.

Year-round heartworm prevention helps ensure your pet is covered before mosquito activity increases. Preventive medications are effective and much less costly than treating an active infection.

Consistency matters. Missing even one dose can leave your pet vulnerable. Our veterinary team can help you choose a prevention plan that fits your pet’s lifestyle and health needs.

Tip #2: Protect Your Pet from Lyme Disease with Tick Prevention

Ticks become active as temperatures rise, and they are commonly found in wooded areas, tall grass, and even suburban backyards. Lyme disease is one of the most well-known illnesses ticks can transmit to dogs.

Preventing tick bites is the best way to reduce your pet’s risk. Monthly flea and tick preventatives are a reliable first step. In addition, checking your pet after outdoor activities can help you spot and remove ticks before they have time to transmit disease.

Focus on areas where ticks like to hide:

  • Around the ears

  • Between the toes

  • Under the collar

  • Around the tail base

If you find a tick, removing it promptly and correctly is important. Our veterinary team can guide you on safe removal and next steps if needed.

Tip #3: Know the Early Warning Signs of Infection

Even with prevention, it is important to recognize early signs of illness. Catching symptoms early allows for faster care and better outcomes.

Heartworm symptoms may include:

  • Persistent cough

  • Fatigue after mild activity

  • Decreased appetite

  • Weight loss

Lyme disease symptoms in dogs often look like:

  • Limping or shifting lameness

  • Fever

  • Swollen joints

  • Lethargy

These signs can be subtle at first. If you notice anything unusual, it is best to contact our veterinarian for guidance. Early attention can help prevent more serious complications.

Tip #4: Schedule Spring Wellness Testing

Spring is an ideal time to check in on your pet’s overall health. Annual heartworm testing is recommended, even for pets that are on prevention year-round. This ensures the medication is working effectively and that your pet remains protected.

During a wellness visit, our veterinary team can:

  • Perform a heartworm test

  • Recommend the best flea and tick prevention

  • Discuss lifestyle risks based on your pet’s routine

  • Answer any questions about parasite prevention and guide you on which products will work most effectively for your pet

These visits are also a great opportunity to stay current on vaccinations and other preventive care.

Tip #5: Reduce Parasites in Your Pet’s Environment

Prevention does not stop with medication. Managing your pet’s environment can lower the chances of exposure to mosquitoes and ticks.

Simple steps can make a big difference:

  • Keep grass trimmed and bushes maintained

  • Remove standing water where mosquitoes breed

  • Clear leaf litter and yard debris

  • Stick to well-maintained trails during walks

While it is impossible to eliminate every risk, these small changes can help reduce your pet’s exposure.

Healthy Habits Start This Spring

April is the perfect time to take a proactive approach to your pet’s health. Starting heartworm and tick prevention early helps protect against diseases that are far easier to prevent than to treat.

If your pet is due for testing or you have questions about the best prevention plan, schedule a visit with our veterinary team. A simple step today can help your pet enjoy a safer, healthier season ahead.
