Lungworm can be transmitted to dogs by slugs and snails.

Lungworm can be fatal to dogs

The lungworm, Angiostrongylus vasorum, is a parasite that can cause serious health problems in dogs, and can be fatal if not diagnosed and treated.

But it can be prevented

Preventative products are available, but can only be prescribed by a vet and must be given monthly. Always speak to your vet because not all wormers are effective against this parasite.
