Heartworm (Dirofilariosis) is a serious and potentially life-threatening disease in dogs, caused by a parasitic worm (Dirofilaria immitis). The larvae are transmitted through mosquito bites, and over time, the worms develop and live inside the heart, lungs, and blood vessels. This can lead to severe heart and respiratory problems if left untreated.
Here in the Algarve, the climate is warm and humid, creating the perfect environment for mosquitoes. This makes heartworm a real risk for dogs living in or visiting the region. The good news is that heartworm can be prevented. There are several effective options:
- Tablets or spot-on treatments – These stop larvae from developing into adult worms.
- Vaccination – Provides long-lasting protection against heartworm with a single dose, ideal for owners who prefer a simpler solution.
- Mosquito control – Reducing exposure to mosquitoes (especially at dawn and dusk) adds an extra layer of protection.
Regular prevention is much easier and safer than treating an established infection, which can be very difficult and risky. At Naturavet, we recommend discussing the best prevention plan for your dog based on their lifestyle and needs.
