The lungworm (Angiostrongylus vasorum) is a parasite that can cause serious health problems in dogs and can even be fatal if not diagnosed and treated.
Slugs and snails carry the lungworm larvae, and dogs can become infected when they accidentally (or purposefully) eat these common garden pests whilst rummaging through undergrowth, eating grass, drinking from puddles or outdoor water bowls, or pick them up from their toys.
The lungworm Angiostrongylus vasorum is now endemic throughout much of the UK.
