Can anyone with Lung Worm experience advise me please. My vet is wanting us to have our dog treated with Lung Worm medication because he says there is a lot of it around and because our dog is a bit of a scavenger he's concerned that he may be a carrier. Now, we're not in to putting medications in to our dog unless he's unwell and wondered if this is really necessary. We've been told very little about Lung Worm...only that the treatment is done via a spot on, on the back of the neck and has to be continued for a while...that it can cause a bald spot of hair that may not grow back and that there isn't a good enough test to predict whether a dog is a carrier or not. We're unsure what to do and really need help and advice. Thanks.
