Lungworm in dogs, caused by the parasite Angiostrongylus vasorum, is an emerging health issue that has spread across the UK, particularly in the southern regions but increasingly throughout the country. This parasite lives in the heart and blood vessels supplying the lungs, causing a wide range of symptoms. With changing weather patterns and increased rainfall, cases have become more frequent, and awareness among dog owners is essential to protect pets effectively.
Lungworm is a parasitic infection primarily contracted when dogs ingest infected intermediate hosts such as slugs, snails, or frogs. These creatures thrive in the moist British climate, making wet weather a key factor in lungworm spread. Dogs that enjoy sniffing and licking outdoors, especially in wooded or long grass areas where these hosts dwell, may accidentally consume them. The parasite migrates through the dog’s body and lodges in the heart and nearby blood vessels, causing serious health issues.

Lungworm can be challenging to diagnose because its signs often mimic other common ailments. Symptoms may vary from mild to severe depending on the disease’s progression and the individual dog. Crucial early detection can make all the difference, so vigilance is key.
If you notice any of these signs, consult your vet promptly. Diagnosis usually requires several stool (faeces) tests as the parasite larvae may not appear in every sample. Blood tests and sometimes chest X-rays may also be necessary to confirm the infection and assess lung damage.
The good news is that lungworm is treatable. Vets typically prescribe antiparasitic medications such as fenbendazole, ivermectin, or moxidectin combined with imidacloprid, often administered for several weeks. Anti-inflammatory corticosteroids may be given to reduce inflammation resulting from dying parasites.
Most dogs respond well to treatment if diagnosed early. However, severe cases can lead to lung damage, bleeding disorders, or even death if left untreated. In critical situations, hospitalisation for oxygen therapy and supportive care may be necessary. Some dogs might experience chronic respiratory issues or require ongoing management.
While no method offers complete protection, there are steps owners can take to reduce risk and keep their dogs safe:
Responsible ownership also means maintaining good parasite control and seeking veterinary advice promptly if you suspect illness.
Lungworm is a serious parasite that can be life-threatening if untreated. However, with increased awareness, early detection, and effective treatment options, the prognosis for most dogs is good.
Ultimately, understanding the risks and signs of lungworm empowers you to make informed decisions about your pet’s health - a responsible owner’s greatest gift.
Quick Answer: Lungworm is a dangerous parasitic infection caused by Angiostrongylus vasorum that affects dogs' lungs and heart, spread mainly by infected slugs, snails, and frogs.
This parasite lives in the heart and blood vessels around the lungs, causing respiratory and systemic illness. It often leads to coughing, breathing difficulties, bleeding disorders, and lethargy if untreated. Diagnosis requires veterinary testing, and treatment with antiparasitic drugs is effective if started early. Prevention focuses on avoiding exposure and regular worming. Lungworm is increasingly found across the UK, so staying alert to symptoms is vital for timely care.
