I read in my dog mag that there is a lot more lungworm around. Dogs can catch it by licking snails and slugs and toads - that kind of thing. I phoned the vet to ask about it and if it is preventable. Worming is SOOOO important, but she said that Drontal doesn't cut it for lungworm. There is another drug called Milbemax which can be helpful. I've only ever wormed with Drontal. Has anyone used Milbemax? The vet said very little about their experience of lungworm apart from a few dogs needing to stay on a drip for a while.
