Understanding Lungworm (Angiostrongylus vasorum) in Dogs
Lungworm (Angiostrongylus vasorum) is a potentially deadly parasite that affects dogs, and if left untreated, it can have serious, even fatal consequences. Early diagnosis and treatment are essential to help ensure your dog’s recovery.
How Can My Dog Get Lungworm?
Lungworm larvae are primarily carried by slugs and snails. Dogs can become infected either deliberately or accidentally by coming into contact with these creatures. Activities such as rummaging through undergrowth, drinking from puddles, eating grass, or playing with toys that have been in contact with slugs and snails can all increase the risk of infection. The larvae are released into the environment via the molluscs’ slime, and when dogs ingest this slime, they can contract the parasite.
Once infected, a dog will pass lungworm larvae in its faeces, and slugs and snails can become infected when they come into contact with the contaminated faeces.
Is Your Dog at Risk?
Any dog, regardless of breed or age, can be affected by lungworm. However, younger dogs tend to be at higher risk due to their natural curiosity and tendency to explore. Dogs that have a habit of eating slugs, snails, or other creatures are also considered at greater risk.
How Is My Dog Infected?
When a dog consumes an infected slug or snail, the larvae are released in the intestines. From there, the larvae burrow through the gut wall and travel towards the heart, where they mature into adult worms and begin to reproduce. The larvae are then carried via the bloodstream to the lungs. Inside the lungs, new larvae hatch, burrow into the lung tissue, and are then coughed up by the dog. Once the dog swallows the larvae, they are eventually passed out in the faeces, continuing the cycle.
What Symptoms Should I Look Out For?
The earlier lungworm is detected and treated, the better the chances of recovery. Common symptoms of lungworm in dogs include:
- Breathing difficulties: Persistent coughing or tiring quickly during exercise.
- Poor blood clotting: Dogs with lungworm may have wounds that won’t stop bleeding, or they may experience nosebleeds.
- General sickness: Symptoms like vomiting, diarrhoea, weight loss, and a poor appetite are often seen.
- Behavioural changes: Dogs may become lethargic, depressed, or, in severe cases, may experience seizures.
If you notice any of these symptoms or are concerned about your pet’s health, we recommend contacting your vet as soon as possible for a check-up.
How Is Lungworm Treated?
Lungworm is treatable with medication, if diagnosed early enough.
Can Lungworm Be Prevented?
Yes! The best way to prevent lungworm in your dog is through regular, monthly preventative treatments, either in the form of tablets or spot-on treatments. Not all flea and worming treatments include protection against lungworm, so be sure to check with your vet that your dog’s treatment plan covers this parasite.
