At the AVMC, to our knowledge, we have met just one dog with this disease, which means it is NOT prevalent. However, we cannot say there is no risk.
If you are concerned about your dog, faeces and serum samples should be sent to a bona fide veterinary laboratory for testing for Angiostrongylus vasorum.
In cats, the disease is a little different. The parasite is Aelurostrongylus abstrusus, which is usually picked up by cats from mice, voles, frogs, lizards and other small creatures, which act as ‘paratenic’ hosts. Cats are much less likely to eat slugs and snails.
