Lungworm (Angiostrongylus Vasorum)

Lungworm Lifecycle

Midforest Veterinary Practice is warning dog owners to stay vigilant for signs of a potentially fatal disease which is affecting dogs across the country. Lungworm infection, caused by the parasite Angiostrongylus vasorum, is a condition which can be fatal if not recognised early and treated correctly.
Dogs become infected through eating slugs and snails which can carry the larvae of the parasite. Once seen as a problem in isolated areas, this parasite appears to be spreading. The veterinary community has worked hard over the past year to make owners aware of the danger. While more people seem to have heard of the condition and recognise that it can be fatal, there is still a lack of understanding as to how dogs catch the disease and what symptoms to look out for.
This particular lungworm is able to live in most species of slug and snail. While some dogs will eat these common garden visitors on purpose, the hidden danger arises from small slugs and snails which can be accidentally swallowed when dogs are drinking from outdoor water bowls, playing with toys left out in the garden, or rummaging through the undergrowth. Certain slug species appear to be more effectively surviving through the winter, meaning they become more abundant in certain areas, while our recent wet summers favour breeding conditions for slugs and snails. Experts believe these factors could be aiding the spread of the disease. Movement of foxes, which can also become infected with the parasite, may also play a role in spreading the disease to new areas.
Dogs which have picked up a lungworm infection can show a number of different symptoms. This lungworm often gives rise to breathing difficulties, ranging from a lack of energy to coughing. Dogs may also show general signs of being unwell including weight loss, reduced appetite and vomiting. Persistent bleeding, even from minor cuts is also a sign to watch out for. However, the symptoms can be varied so if owners are concerned about their dog’s health, they should contact their local veterinary practice for advice.
Thankfully treatment is available although conventional use of worming tablets is not effective. Vets can prescribe a specific spot-on treatment to deal with the infection. Owners are urged to look out for the signs of the disease and report them to their veterinary surgeon immediately as taking action early will improve the chance of recovery.
