Now for lung worms i will elaborate a little of what i know about them. lung worm can kill your frogs and toads simple as that and you will never even know they have lung worm. I am not aware of the treatments for it. But I do know that they are rare. They are carried in snails and slugs as well as fresh water crabs. Lung worm is said to be eradicated in the continental U.S. However lung worm is found in many Asian country's. Lung worm can effect pets such as dogs, cats, fish, frogs, toads and even us. I do know lung worm is very dangerous to humans and can be treated. Where we encounter lung worm is when we have frogs shipped from country's where lung worm is found. Now if you have a CB frog in the use or even the D.R. and you do feed your toads snails chances are they wont catch lung worm BUT there are plenty of other parasites to take its place.
